Hi,

Have you solved the buzzing issue for your TV. I have got PS50B650 for two days and the buzzing is not tolerable. I thought I will return plasma tv and will take led tv instead but just found your blog when googling. I found reports of this problem around the world, is it a common problem for bigger screens, as I found reports on other marks as well: panasonic, pioneer. I am from Slovakia and on one Poland forum I found quite a lot of users of PS50B650 reporting the same buzz issues.

Best regards
Stefan

I just began having the same problem with my UN40B6000.

I have the UN40B6000 LED also and am having the same issue. There is this odd noise that comes from the back top part and it’s not obnoxious – it’s noticeable. It is dependent on the amount of light being displayed on the tv. I.E. if its just credits running against a dark background the sound is low as opposed to a bright scene and the sound increases. I bought it at Best Buy, and it started 2 days after I got it – went back and returned it – got another and exactly 2 days later its doing it again. I am going to let it run for a day or two non-stop and see if maybe something does have to “burn” in as mentioned. I LOVE THIS TV and the picture is amazing! But for the price you shouldn’t have an issue like this. If anyone knows anything let me know! I want a solution to this!!!

So did it stop after you got this new one? I am still under my 30 days at Best Buy – Hell it hasn’t even been a full week! But this is my second new one. Don’t know what I would get or try after this. Series 7 or just go LCD…different brand? UGH!

@Pat, let us know if your replacement unit solves the problem.

@Markus, that’s one way to fix it! 🙂

Update: After a month, my replacement unit only exhibited the buzzing once. Satisfied that it’s probably OK now, I’m calling Samsung to request extending my original warranty from the date of the replacement unit installation. Also, a tip, a customer care rep said that if you register your TV online, they’ll add another 90 days to your warranty. I haven’t confirmed this but given the nature of these sets, I would urge everyone to do it.

Buzzes LOUD right out of the box. Samsung will not honor the warrantee, so far I have had no response. Tech came to house and agreed the buzz is there and loud and gets worse with altitude. There is no fix and from what I can tell, they are not taking them back. a class action law suit is really needed to stop this nonsense. The buzz is a design flaw and unacceptable. I have been trying for 5 weeks to resolve this, but Samsung has not given me any indication of resolution. DO NOT BUY A SAMSUNG PLASMA!!!! too bad, great picture, but nasty loud buzzing. At least above 5000 feet from what I have read, they just don’t work right.

I purchased a UN40B6000 (LED) and it worked flawlessly for over a year. Just recently thought the sound became distorted, almost like a speaker was blown, but it comes and goes (an hour at a time).

It appears to be related to a certain sound frequency (e.g. it happens more with women speaking than men), and when it happens it is difficult to understand dialog at all.

It does seem to be emanating from the left rear of the set, so I started to wonder if there was a vibration occurring triggered by a certain resonant frequency.

Haven’t called Samsung yet — I’m dreading the runaround, tech visits, and ultimate shoulder shrug I know is out there for me…but it looks like that may be the only option.

I purchased last week a UE32B6000VW and after 2 days of use it started to make the buzzing noise that everyone has stated, there just doesn’t seem to be any pattern with it whcih is what makes the problem even more annoying, it seems to get worse a night for me as I can go for hours in the day without a sound.
I also think I have a issue with HD picture as when watching movies via HDMI from laptop I get lines moving from the top to the bottom when there is any fast screen movement. I’m not sure what this could be down to the laptop is outputting at 1280 x 720, I haven’t tried a blu ray player as I don’t own one so can tell if this happen at full HD, but even so for the price you pay there shoudn’t be issues like this.
It’s a great picture so am reluctant to send it back but if it can’t do what it is designed to do then I may have to.

I am on my second unit because of this problem. It is strange (and annoying!!) because sometimes it will stop (or start) from just changing channels or if the next scene is significantly lighter.
Morgan, I will try leaving the TV on overnight to see if it resolves the problem but I am not convinced.
When I was looking into different TVs I thought I would go all out and get the best one and spend a bit more. Now I wish I just bought a normal LCD at a fraction of the cost.

I’m not sure whether this is the same sound referred to above.I have a new Samsung 55″ B6000 LED. The sound coming from my set is a very high pitched sound (I thought possibly power supply). It interacts with the audio and to me is quite irritating( causes ears to ring). My wife doesn’t notice it. I knew that with CRT sets this effect is quite common but hoped LCDs/LEDs would be OK. This shop I bought it from is very reputable and are prepared to exchange it but I am very worried the new one will be the same.

Guys, you are not alone and I am having the exactly same issue. I just purchased a Samsung PS50B850 TV from Ebay. The TV has an amzing picture quality but you can hear a notiable buzzing noise from the power supply unit at the back of the TV. If I turn on the volum size more than 10, the noise will be covered. I contacted the supplier and they told me that the buzzing noise is very normal. Because it’s a factory second unit, the supplier could provide the back to base warranty. I really don’t know what to do… any suggestion guys? Thanks heaps

I bought a samsung 46 6000 series on thanksgiving had soo many issues with it returned it 4 times fifth time i just upgraded to the 46 inch 8000 series, but im not getting a buzzing sound but when i change channels its making little cricket sounds..is this the sound you guys been hearing??

By the way, I have the 40B6000 model

Hi – Another update. The Samsung tech came by once again, changed the panel but no change. The unit still buzzed. I stressed that we’ve had the sockets checked but he said that it doesn’t matter, the problem is with the TV not the electricity in the house.He took the TV to Samsung.

Today he called and said they can’t do anything and that they will return the TV, the problem cannot be reproduced they said and it must be something with my wires/power in the house.

Sigh!!!!!!

I have no hope what so ever that this can be fixed now…
Model UE40B7070.Avoid like the plague.

Same deal… I’m on my second UN40B6000 led tv and it makes that annoying buzzing sound. I paid too much money for a tv with these sort of problems. The Samsung tech(s) that I spoke with both say they haven’t heard of this type of problem before. After reading this post, I’m not so convinced.

I’ve always heard great things about Samsungs, I know three people that own Samsungs and they are all in love with them. But unfortunately, I am not as in love with the TV as I thought I would be. So I guess I am going to try a new brand. Any suggestions?

I have the 40″ 6000 series for alittle over a month now and it makes the famous buzzing everyone is talking about…. bought it from best buy. Not really sure what I can do at this point, wish i would have seen this website sooner… I use external speakers but the screen itself is so loud… I wish i would have gotten a 240 hz but now I wish I would have gotten a different brand…

On our first un46b8000 a vertical pink line appeared on the right side after the tv was on for a few minutes, we sent it back and got a replacement. The second one started buzzing once in awhile, sometimes it’s perfect then it’ll be quite annoying. They’re picking it up tomorrow and I’m getting a refund.

At least Futureshop isn’t screwing around.

Hi,

Just a quick word to give my support to all people with buzzing problems on SAMSUNG TV sets.

I was thinking to buy a UE32B7020 appliance and after reading this blog and other web pages where the same buzzing problem is mentioned without an official answering from SAMSUNG I have decided to wait until a LED mature technology will come to the market. It is a pitty because yesterday and today there is a special offer in Madrid (Spain) through Media Markt supermakets, coming back to you the taxes (16% free of charge). I think it is much better for me wait for one-two years reviewing the LED (even OLED) technology

I have the same exact issue! I’m really dissappointed to have read this now. I didnt keep a reciept and I really regret this may be a big issue. I will still try to call it in and see what type of help they can provide me. I have a phillips tv as well and it has never given me any issues. i refuse to buy another samsung lcd tv, despite the fact that the picture quality is amazing, the annoying buzzing sound is too loud to block.

BTW – the buzz issue prompted me to register my product online. The confirmation email I received as a result of registering also confirmed the three month warranty extension mentioned earlier.

“This message confirms that your FREE 3-month warranty extension has been activated.”

Just made my complaint to BBC Watchdog!!! Everyone should do the same!!!

I have the same buzzing noise as well with my unit. been dealing with it for the past 2 months now. The buzzing comes and goes but I have been noticing it a lot more lately. I have done some research on this issue and may have found a solution. i found a website that states that, “The buzzing is not caused by the power supply, like first assumed, but from the plastic on the back of the screen that is too thin causing it to resonance. The buzzing can be resolved by adding a rubber washer in the back of the TV.” I have already called Samsung to arrange a tech to come to my house to have a look at it and to see if this could be the solution to this epidemic problem. I will keep you all updated once the tech comes and hopefully this will be the fix.

Hey everyone, me and my Samsung LED 6000 series just had our first experience with the buzzing noise from the top right of unit (looking at it from viewpoint). I usually use the power saving settings set to high. I had the power saving setting off when the buzz arrived. When I heard the buzzing noise I turned off the TV and turned it back on and even the startup noises were distorted with the buzz noise. It is not any of the speakers though all are fine. I thought it could of been some type of distortion from my Laptop hooked up through HDMI though it wasn’t. I lowered the volume on my T.V. to 0. Buzzing was still constant and only slightly lower. So I decided to give up since it was late and deal with it in the morning. I was going through the menu to set up how I wanted the picture, brightness, etc, etc and I notice my power saving was off, I turned it to high. The buzz disappeared. From what I can tell from the comments above it seems to be very sporatic. Will update my situation. TRY USING POWERSAVING ON HIGH. So far it has remedied my buzz. Good luck.

Bought my samsung 40″ series 8 led tv back at the end of feb. Right out of the box I had the buzzing noise. But here is the weird thing it only does it after 19:30 never in the morning or through the day. Tried the tv with everything in the house turned off. With no input the tv still makes the buzz.

After the third repair today (and every part being replaced) I’m beginning to loose hope on ever getting this problem sorted.

I had the buzzing sound on my LED model and it was really annoying… Sometimes giving me a headache so I would just switch the entire tv off and read instead!!!… or go to another room.

BUT thn I turned off the energy saving in the device and the sound went…. So I fiddled around for a little and found that if I turned down the backlight the buzzing sound returned…. And also during adverts or programmes if there’s a dark screen it comes back, only for the time the screen is dull.

So the answer is…. Bump up the electrical consumption… Check that ur energy saving is switched off and that the backlight is on full and brightness set to around 60 should work. It’s s little like a dimmer switch I guess… When it’s turned half way for dim lights, if you put your ear to the switch u can hear a buzzing sound. Hope this works for you guys x

Just as everyone who listed there issues and concerns. I purchased a Samsung UN55B8000 in late January. Two and half months later I heard a buzzing sound coming from the TV. The sound comes and goes. My wife called for service, they told her to call them back when the sound comes back on….. that’s bad business. Yesterday night I was pissed and called and asked if someone can come out and take care of this issue. Besides the buzzing noise, theirs a flashing white horizontal line appearing on the top of the screen every once in the while. I also have the light flashing 4 times. Samsung needs to resolve these issues. I want these issues resolved.. Does anyone else have these problems?

For those of you experiencing a hum or buzz on the Samsung LEDTV. IT MAY NOT BE THE TV. We discovered that the buzz-which was intermittent and appeared at night around dark and disappeared in the morning-was due to a burned bulb on a photo cell censored flood light on the outside of our home. This fixture is on the same electrical phase in our home The burned out bulb sent feedback or harmonics-back through the electrical/power supply and the sensitive LED picked it up thus causing the buzz,. When we replaced the bulb on the outdoor fixture, the buzz stopped immediately. What a revelation!!! So if you are having this buzzing problem, check all electrical fixtures and switches that could be causing the problem. We love our Samsung LED—the picture is just outstanding.

@Adam: Yours is a different problem related to the speakers. The buzzing that others here have experienced emanates from the panel itself or associated electronics. For buzzing from speakers, others have suggested checking your electrical connection to see if it is on the same circuit with a dimmer switch or lamp with a dimmer. Dimmers can generate a lot of RF interference that can backfeed into your audio. Good luck on your problem and let us know what the solution is for you.

I had the samsung 37″ LED full HD TV and this buzzed straight away at the top left rear corner looking from the back. I was so annoyed I took it back the next day and Currys gave me a full refund, no quibble, great service by Currys . I really liked the picture though and now Iam struggling to find an alternative LED 37″ or maybe 40″ unit, perhaps Sony is the next choice?

Can anyone advise please?

I’ve just had my UE46B7020 swapped out, and new one still buzzing intermittently, depending on day or night – mostly at night.

One night it wasn’t buzzing and my brother went downstairs, it started buzzing, I went to see what he was doing and he had turned the kitchen light on, but dimmed the lights using the dimmer.

It was this that was causing the Buzzing noise – possibly some electrical interference. So before you call out a Samsung Engineer check your electrics first.

First of all thank you so much for this website! Everybody’s experience and tips were extremely useful.

My parents bought a Samsung 46′ LCD HDTV and right from the start they could here buzzing from the set. They tried calling Best Buy (where they bought it) and Best Buy said it was a problem with the cable box. My parents had the cable company come to switch the box to a HD cable box and the cable guys could hear the humming/buzzing as well. They said to call Samsung. My parents called Samsung but didn’t get any real help. After searching the web I found this site. I told my mom that people were having the same problem with their TVs and there seem to be 3 different solutions. One was if there was a dimmer in the house it may be causing some sort of electrical interference. My mom said that she could hear the humming/buzzing all the time – day or night and that the only dimmer in the house was not on. Next was the Power Saver. She checked that (it was set on OFF) and turned it to HIGH and it stopped the humming/buzzing (YEAH!). The only problem was that the picture was now a more muted color. She then adjusted the Power Saver to LOW and the humming was gone and the picture quality looked fine. She didn’t try adjusting the Backlight that others have tried since the Power Saver adjustment seemed to solve the problem. I told her to let me know if the humming comes back so I can update this post but for now it looks like the problem has been solved. She was very distressed about the humming since they had spent almost $1000 on the TV and was greatly relieved to find a way to fix it herself.

Thanks again Morgan, Jake (for his solution) and everyone else who posted!

Good night from Spain,
I bought my Samsung LED 37 Series6 and after 5 months start buzzing. It does not follow any pattern, sometimes I switch it on and starts buzzing, and then stops and other times it starts buzzing and does not stop in a couple of days. I phoned the technicians and after 2 weeks they brought my tv back. 2 weeks later it started buzzing again and the buzz sound louder! This afternoon I went to the store where I bought the TV, a spanish famous giant El Corte Ingles and thwey told me I had to phone again the technician.
Tomorrow I will phone the technicians again. I will update asap

I believe there are two different problems described in these blogs. One is the resonating sound the tv makes and the other is a sound distortion that comes through no matter if you play sound through the tv speakers or run the tv’s sound to an external speaker system. Both problems come and go seemingly at the tv’s discretion, making the owner go crazy troubleshooting so far as to make an electrician come to your house to check wall outlets…lol. Anyway I figured out it was the tv because I could literally unplug the cords while the tv was making the distorting sound and plug them into another HD television and have perfect sound. Doing this back and forth to be absolutely sure of myself was not merrily enough. I would play the tv’s internally sourced sound test while the distortion ghost was having his way and it too would be distorted. Making my way to sears I traded in the four day old tv for what was thought to be a none broken one. After setting it up, to my dismay I realized the 55″ led had a design flaw. Same distortion coming and going whenever the tv chose. The sears people were so simple minded they couldn’t even understand what I was saying and how I came about figuring this out. They thought I was crazy and had a vendetta against samsung televisions. I tried explaining to them when they plugged it in and it had no sound distortion that it came and went and blahblah all the troubleshooting I did to figure out it was a design flaw.. There’s no way two tv’s in a row can b broken. That’s why it’s a Design Flaw!… you idiots! Looking dumb they just said I was crazy but they were obligated to let me pick out another.. I said if this Sony 55″ led does the same thing and it is indeed one of my electronics, I will come back kissing your feet begging for forgiveness. Two months later my beautiful non defective Sony is perfect with no sound distortion.. Thanks sears and shame on you samsung for not recalling your trash.. You caused me to gain many grey hairs and lose even more faith in humanity. De- evolution in it’s purest

There are just too many sets out there with the same problem! Seems to me to be an electronic design problem that Samsung does not want to deal with. My 55″ set is 18 months old, has a great picture but I am still bothered by the loud, intermittent buzz. Even with the sound muted and volume at 0, the buzz is still there. Most of the time, I can contend with it since the TV volume mostly overcomes the buzz. It sounds like a transformer that has a loose mounting but who knows. I have checked all the things in this blog but still to no avail. I will keep and eye out for anyone who may come up with another solutions.

So I recently noticed my Samsung LED buzzing also, so I googled it and got this blog. Upon finding this blog I came back out to the living room and turned on the TV…..no buzz, huh? Then I read Greg’s post about buzz problem solved about poor power filtering in the house. I thought to myself I started noticing the buzzing around the time I put up my christmas lights outside. Sure enough I flipped the switch on for the christmas lights outside and the buzzing started, turned them off, no buzzing! Go figure, problem solved and I can enjoy my tv again!

Thank you thank you thank you Kerry M !! I have the UN40B7000WF and just discovered the buzzing a couple of days ago. I thought “oh great, it’s going bad already” and I’ve only had the TV for about 9 months. I checked the wiring of the TV and all the home audio components, and I checked the TV and cable box settings, and figured what the heck I’ll google this.

Thanks to this web site and Kerry’s explanation I ran across the room to the light switches and discovered that the kitchen dimmer was set at about 80%… I turned it off and like magic the buzzing went away COMPLETELY!! It also doesn’t buzz at full power. Only when the lights are slightly dimmed does the TV buzz. Note that 2 out of the 5 bulbs are fluorescent, and 3 are incandescent. Not sure what will happen if they’re all the same, but I’m going to try it.

Thanks!!

Hey I have a UN40B000VFXZA recently I’ve noticed that my TV is making a buzzing sound so after reading all this question and answer I went to BESTBUY and bought me a Monster Flatscreen powercenter 350 for $59.99 so far so good no buzzing.

Unbelievable! I purchased my UN40B600 in November of 2009 and tonight I turned on the set and immediately noticed the infamous buzzing sound emanating from top back of the set. I guess I should feel lucky in that I got over a year’s worth of service before the buzzing started. Oh crap…. I guess that means my warranty has expired! Most likely I’ll just go find another brand to replace it with. From what everyone is saying, it takes at least 3 or more trips by a service tech to NOT get it fixed. I did call Samsung and they gave me the link to a document that tells me to check my cables and connections and if that doesn’t work then place a request for service call. It’s such a great picture. Unfortunately, only a deaf person could stand to watch it. Oh woe is me…

I got my UN55C7000 LED 3D in Oct 2010. I am disappointed that a year after Morgan’s issue they are still handing out units with the same flaw. Mine has an electronic squeal coming from the upper right (facing the front of the TV) and an intermittent cricket-like chirp. It was fine for several months.

This website Rocks!!! you guys totally found the solution to my problem.

I have a UN55B6000VF I have had it for over a year and love it. Suddenly it started the crazy buzzing noise. I called Samsung and they told me it was out of warranty and I would have to pay for a tech. I found your website and was able to determine the problem was a laptop power supply plugged in beside the tv was causing the buzzing. I am very happy that I can cancel the tech. It would be helpful to post something at the top of the page so the next guy doesnt have to read 100 angry posts 🙂

i had the same infamous buzzing issue. I’ve read most posts and started getting convinced that something was wrong with my unit. and then something crazy happened.
i turned off the ceiling lights in my room while the TV was on, and the buzzing disappeared. if you tun off some switches in the area where the TV is, maybe this could help reducing the noise coming from the power cord at the back of the TV. i know it worked for me

I guess I must be one of the few people to post on this web site who does not have a buzzing problem; in fact I do not even have a Samsung TV but I would like to thank everyone who has posted on this board as I was going to buy one tomorrow but will not now be doing so. It is clear that Samsung has not even acknowledged the problem let alone fixed it and I do not want to risk ending up with a buzzing Samsung. I am suprised that the company has not done something about this problem as I would have thought that “buzzing Samsungs” are now sufficiently prominent on the internet to be having an impact on the company’s sales.

hey guys ,,,,just do one thing,,,,,its not the problem of LED tv,,,,its an earthing problem,,,,,,do one thing that is ,,,,cover the earthing pin(the big one among the three pins)with insulator ,,,,and insert it in socket,,,,ur prob is solved,,,reply me @sagardhapatkar@gmail.com ,,,,if it works

FYI to you guys but Samsung isn’t the only one and there’s not much info on buzzing unless people are using the built in speakers which is blasphemy (I am not). My Sony KDL55EX720 is doing the same thing as Markus said earlier in this discussion; the buzz seems to go off based on the current picture displayed only my problem is even when the TV is completely off it still makes the noise. Only time it doesn’t is when you unplug it and I haven’t owned it for less than a month. Contacted Sony and they had me unplug the TV for 60 seconds then plug it from a power strip into the wall outlet which didn’t fix anything. Now they want me to contact customer service for repair so I’ll be holding on for that ride!

Wanted to also mention I got this TV after I just purchased a Panasonic Viera 55″ ST30 which developed a thin black line running horizontal about 4-6in from the bottom of the screen. Contacted Panasonic and they wanted to send out a tech but I was about to run out of my 30-day return policy so I just took it back and purchased this Sony but I guess that was a mistake. Supposedly both good companies and I’ve officially tried a plasma and now a edge lit LED both having nasty issues within 30-days. My old Sharp Aquos LCD never gave me this BS what the hell? Just a FYI since Panasonic is one of the top plasma companies for anyone thinking about converting.

Wow…seems there is certainly a problem with Samsung’s LED/LCD line, which is unfortunate because they are outstanding in just about every other category. I have a 46″ LED, B6500 series and I’ve had my set for just shy of a year now. The buzzing is quite annoying and is very intermittent, sometimes it will fade away, but has been rather consistently distracting me from viewing anything lately. Where to go from here?…Store?…Samsung?…Repair?…Replace?

Hello from Finland!

I have Samsung UE40C6905 LED-TV and it makes the same buzzing noise everyone is explaining. I get it to go away when I change source from i.e. HDMI1 -> TV ->HDMI1. But I have to say that it’s annoying to change sources in the middle of a movie when the buzzing starts.

Does Samsung recognize the issue at all? What could I do to make the issue go away other than send my TV away to maintenance for few weeks, ’cause thats what it takes over here when they ship it to importers repair. 🙁

Bummer.

just bought a new un40d6000 and hours after installation the buzzing began. It stopped for a day and a half after I plugged in my Ethernet cable and installing updates. And just now it began to buzz. I have taken notice to two variables , 1) I’m pretty sure during the day I can’t hear anything its only night time where I can hear it. 2 depending on the amount of color is being displayed the buzzing gets louder. When changing channels ( the one second of black) the buzzing stops. So I don’t know what the he’ll is going on but I’m doing to be another pain in the ass to Samsung untill I get a non buzzing led tv.

Thanks Morgan and all posters, having experienced the buzzing noise with a Samsung 40″ 6000 series, i have gone thru all the troubleshooting, having identified that is was the PSU board “buzzing”, i have started considering the replacement of the component, that would have probably been a waste of money!!. The reason is really noise in the AC socket (in Europe a 220V) and having gone around the house testing different socket i found that only the one the TV was connected gave the buzzing issue. I purchased a new power strip and rewire all my AV setup to the new socket and problem solved. TV has been running now for over a week and no buzzing noise.

Problem Solved (so far): I bought a Samsung LCD (LN32D450) and it was having buzzing issues until I put the power cable in an entire different socket, and buzzing gone! There is certainly a relation between the power socket you use and the buzzing noise, at least for some people here.

Try as many sockets as possible.

Good luck to everyone else

I am hearing buzzing sound from My samsung (UN55B8000). Tried calling samsung and they said that they are not aware of this problem. I am amazed that a bunch of Liars are sitting there and lying to customers. Dear Friends please suggest the solution.

My model is a samsung: UN40B6000VF, and I’ve had this buzzing for more than a year. It comes and goes, and it’s on the top right side of my tv. I paid $1,500 for this LED samsung tv and now I checked that to many people have the same problem with this samsung tv. I hope that it’s a good idea that all of us that has/had this samsung tv would have a re-call. This is because this tv i very expensive and it has a very cheap quality. I’m never buying from samsung again; only from sony. Thank you.

The buzzing began about a week ago and is intermittent. It is not too terribly loud sounding like a fly by your ear. The Samsung LED is about 2 years old so there is no warranty, We’ve already put $400 into it when it wouldn’t turn on. Reading all of these comments doesn’t make me too hopeful.

I was just watching a movie (via usb) and it would buzz randomly throughout the movie. I’ve heard it buzz a little before but didn’t think much of it and thought it was part of the sound coming from the actual commercials or tv program I was watching. It’s a 4oue6000 that I just got 2 weeks ago. And after reading all these comments it seems like a waste of time to try and repair/replace it. What a shame, the picture is excellent. Now if only I remembered where the receipt is…

Just bought 32 Samsung UE32 model get severe sound distortion on certain frequencies ITS GOING BACK Oct 2012

Bought a brand new Samsung UN55ES6100 – 55 inch LED Smart TV in July. I had it buzzing about 2 months ago…. It did seem some kind of cable interference since I am using a COAX without the digital box…and I thought it was a loose connection..I think it went away after I tightened the connection, but not sure if that was the problem. It is a very distinct buzzing sound which can be heard even after disconnecting all cables, and muting the sound. The buzzing stops when you are changing channels and thats why it is so easy to make out.
After reading through this blog…. the first thing I want to do is find my receipt and get this exchanged. I dont want to get it fixed and have it come back after 2 years !!
Never had a problem with my 6 year old sony 46inch LCD….

I bought the UN55EH6070. The default setting has the LED motion plus turned off. about 2 months later i decided to turn this feature on for better picture quality ,which it did , and then i began to notice a low humming noise eminating from the tv which would stop only when the screen went dark changing the channels.The speakers are set to off,( using a sound bar) so i knew it wasn’t that. I decided to turn the LED motion plus back to off for the hell of it and ta da da the humming noise is gone. Is this an actual defect of the tv? or is it normal? I still have a year on the limited warranty.

Hi:

It seems in some of these posts people are getting wise to the fact that’s not the TV itself per se. It’s that the TV needs “clean” power.

My TV buzzed, especially with a bright screen. When I attached it to a high quality computer battery back-up (UPC) that “conditions” the power it stopped completely.

What turned me onto this is I caught a connection between a panel of dimmers in my living room being on and the buzzing getting worse.

So, I’m at a half solution because having a big bulky UPC by my TV is a bummer. I bought a $100+ commercial quality powerstrip with “line conditioning” and it didn’t work. I’m kinda bummed because it was by far the best reviewed/recommended unit.

Does anyone have a recommendation for a solution short of the UPC that will truly provide “clean” power?

As an afterthought – Samsung must be insane. Rather than replace all these TV’s and incur the incredible expense and client dissatisfaction, why didn’t they figure it out and provide affected users with some type of “line conditioner”?

Oh well. Really great TV otherwise, too bad I’ve had to waste my time like this.

SOLVED!! My buzzing samsung 65″ led was solved by going into menu/mode and turning the backlight setting all the way down. The tv gets darker but playing with other settings makes it bright again without buzzing.

I have a Samsung 40 UE LED straight out of the box today.
When I mute the volume I hear a bizarre noise coming and going that sounds like the described “pack of crickets”. It´s not loud but I´m really sensitive about my tech stuff not emitting noises. Searching the web for this seem to imply that you just have to live with it.

What do you think I should do?
Get it back to the store or accept the crickets?

Hi, I’m from Bangalore, India. Got one Samsung UA40B7000 from Oct 2009 onwards. It makes not so irritating noise from back of the panel only when on my non sinusoid home UPS. Once the power is back, that noise is gone. Not from speakers as I use external speakers.

With UE55F8000 the problem for months has been that Samsung would not say what hard drive would be compatible.

Having found that WD My Book AV-TV 2TB, (and Buffalo HD-AVSU3 2TB USB 3.0 DriveStation Media) were said to work, with My Book attached came the *HUMMMM* which could be hear best at the other end of the cabinet.

Once it was traced to sound from the hdd being amplified by the cabinet, a strip of pvc foam packing under its rubber feet cured it!

hi reading most of these post seems like a lot of people have had a lot of issues with Samsung TV’s. but all could be slightly different.
I had a similar issue as well so I hope my post will help others.
I have just recently bought a new Samsung smart tv ue40fd6400, I was very pleased with the tv until 4 or 5 days since I bought it as I noticed a buzzing sound which was worrying and I didn’t noticed it before.
I tried using my separate digi Freeview box as I thought it may by the signal and it stopped making the buzzing sound. so at first thought right it must be the tuner in the tv. but then I realised earlier on in the week I started playing round with the picture settings. I went into the settings like as follows:- MENU,PICTURE SETTINGS,PICTURE OPTIONS, MOTION PLUS AND THE LAST I WENT TO LED CLEAR MOTION AND TURNED IT OFF, AND NOW MY TV IS WORKING.
So I hope this post has been usfull.

ue39f5000 suffers the back light hum. Brand new out the box only goes away if you set the screen to LED clear motion which isnt availble when using with a PC or PS4.

Sending it back and changing brand!

Even my cheap LED Chinese tv is silent.

I have the same buzzing issue with two different televisions. One is an LG HD Flat screen and the other is a Sylvania Plasma flat screen. The problem only happens in one room of the house. This room happens to have new wiring because it was a new addition (family room). I ended up moving the LG to the bedroom and it works fine, no buzzing. Interestingly enough, the bedrooms all have the original house wiring which is probably at least 40 years old.

After speaking to a friend of ours, he recommended a UPC filter. He thinks that when the wiring was done, there was no filter added to the wiring for electronic equipment interference. Supposedly, Best Buy carries this UPC filter for approximately 75.00. It plugs into the wall and then the tv plugs into the filter.

I’m going to pick one up tomorrow and see how it works. I do find it odd that the only rooms that affect the sound of both tv’s are the ones with the new wiring.

Bought a Samsung UA55HU8500WXRD: a Samsung 4k 55″ series 8 in Aug 2014.
Had this same buzz from purchase and has not gone away after a week.
Have requested a Service Call. Will see what happens.
I love the 4k picture with decent input, but the buzz is a nuisance; It persists with Muted speakers; also when only recording to external USB and no display.

I just had a UN65H7150 delivered from Howard’s TV. After the delivery Gus left, I settled in for some viewing and heard the “buzz of death”. My salesperson says he will come by tomorrow with a surge protector which will ameliorate the problem. I am unconvinced, but I’ll keep an opened mind. Will update anon.

I have a UN46B6000 I bought when it first came out about 6 years ago and I get a buzzing noise. I’ve tried going through all my settings and using the self diagnosed on the TV but still the noise persists. The interesting thing is if I leave the tv on it will stop eventually and be quite for months!

My TV has had 2 calibrations since I’ve had own it and I’ve ask the techs about it and they aren’t entirely sure to what causes it. I believe it is a Samsung trademark with their TVs.

Hi all ! I repaired a buzzy Samsung LED TV, model UE40D6200, by just changing a resistor on power suppy board. The noise was changing with the content of brightness of picture, and not from audio level.

Agree with F5RCT – the noise is loud and clear and changes with the brightness of the displaying content of the moment. Noise stops on darker scenes, comes back on brighter ones. But I am too chicken to monkey with the hardware in the back so I’ll have to live with it. Didn’t realize this is a common Samsung problem. Samsung got great picture quality comparing to the others I’ve seen. Got a cheap 40″ Element LED TV right next to this noisy Samsung 46″ LED. The Element is a couple years newer, no noise. But the same picture moving from Samsung to Element is like day and night – Samsung is better in every way. I watch movie with headphone, that helps a lot. The noise cancellation kind is even better.

At the tail end of December 2014 I bought a Samsung UN65HU8550 TV which is supposed to be a top line TV. It is now end of May 2015. I watched the TV last night till about midnight. Woke up this morning and switched on the TV – massive sound distortion whenever any sound comes from the TV i.e. music and voice. Whoever talks in a program or movie the voice comes out in a high pitched static-like voice. If you listen carefully you can understand what someone is saying but it is very unpleasant to the ear.

I called Samsung customer service. After troubleshooting for about 15-20 minutes I was told they would have to send a technician. What a drag. Now for coordinating the technician’s visit, taking time out of work etc. etc. I guess most people know the drill.

My biggest fear is that it might be a major problem (God forbid) which may require a lot wrangling with Samsung, now or as time goes by if the problem cannot be fixed. It really sucks that in five months a brand new TV starts giving trouble.

Well I am keeping my fingers crossed and hoping for the best. I will keep you posted.

@Wingnut: This is an interesting discovery and thank you for sharing this. I wonder if it’s the switching power supply vibrating against the back cover of the unit that causes this. (The more power needed by a brighter display setting causes the supply to vibrate more against the back?) Isolating that part from the cover, or sufficiently adding enough material between the cover and part to dampen out the vibration, could very well result in eliminating the true source of the noise. It would be easy enough to test by just applying some pressure against that rear cover in strategic places to see if the buzzing changes.

If that is the source of trouble, it would explain why going through so many part replacements for me eventually solved the buzzing. Sheer random changes in tolerances between components and cover might have done it.

Fortunately, my unit still is working great (see update from May 2015 at the end of the article). I’m happy to hang on to this until it either craps out or there is enough justification to move up to a larger 4K TV.

i bought a samsung 32″LCD series 3000 sometime in 2009, and it doesn’t have a buzzing sound from beginning until now 2017. and it still working flawlessly. however, i had a new samsung smart 3d LED UA55H7000AR very recently, upon setting up everything we play the tv mode with the local antennae connected on it, we heard an annoying buzzing sound. it was so loud which even competes with the sound from the tv program. can anybody help us to solve this issue?

My 2012 UN55F6400AF 55″ has buzzed on/off for 2 years, mostly not very loud, and turning the backlight down to 5/6 lowers it to the point where I can barely hear it. At other times it is so loud I can hear it from my seat 14′ away without problem. Not going to waste money getting it fixed (if it’s possible) and just put up with it until time for a new set, waiting for OLED’s to come down in price some more, and the new set will NOT be a Samsung.

I have a UN55D6000 from 2011. The buzzing started a little after warranty ended so it’s just sat there and now I don’t even use it. The buzzing is loud enough now where there’s no point in using it anymore. It’s probably not even worth spending money on at this point. I’ll probably throw this garbage away and buy a new tv.
