My 54G20 buzzes like mad. Called Panasonic. They put in two new boards (X and Y power boards) the two to the sides in the picture.

Still buzzing like crazy on basically all content. Super happy. I'm gonna call them again tomorrow.

Jamor? What made your buzzing go away?

I'm happy it worked out for you !

Thanks..

I'm not sure how! The only thing I did yesterday was replace really old speakers with new ones. I can't imagine that this would be the issue and only coincidence.

The only thing I can think of is that my new speakers are magnetically shielded and the old ones were causing some sort of interference.

Either that or I watched it enough that the rumor is true that the buzzing decreases as you watch it.

Not really sure.

It's not perfectly silent - if you put your ear behind it you can still hear the normal minor buzz that most Plasmas have.

Certainly much quieter than it was before.

Before when I'd play Madden or watch certain TV (even on THX mode) it was an extremely obnoxious buzz.. It's just not like that anymore.

My build is October 2010 and firmware version is (TV) 0100-0330 and (Status) 01000-40200.


I'm going to do some more testing when I get home later today and make sure it doesn't come back before I cancel any exchange.

I will be dealing w it. Thank you sir, may I have another.

Speaking of the PQ that will blow the doors of the LED alternative, I did a little test while I was juggling what should I do with the G25...


This is not a scientific test in any way. I am not a specialist and I did not use any calibration tools... Just the ootb cinema/thx settings.

The video quality is not super clean (specially on the G25 that had very low lighting) but I can assure you that the G25 was displaying an even black image across the whole screen. In the video, it does not seem even because of the ambient low lighting of the room.

I don't know if LED tvs will ever get the same uniformity and black level as a plasma will but I sure was way disapointed with LED tvs... The G25 busted those LED tvs in that regard...

But man... that stupid buzzing noise...

Jamor...is there any way for you to estimate your usage? Is there a runtime in the service menu or something? How many months have you used it? Did you do 100 hour burn in?

Thinking it also might my speakers I tried removing my speakers to about 20 feet from the TV, but it didn't help. I'll try remove all speakers to another room including my sub tomorrow. The change should be instant i'd assume.
Mine is ALSO an OCT 2010! Also (TV) 0100-0330 and (Status) 01000-40200. Did you too get the Power X/Y boards replaced? Was your noise directional like mine I described below?

This is the SECOND person who has gotten rid of the buzzing through usage. There was another fellow in the owner's thread which ran the burn in slides for approx 8 hours to be surprised the buzzing was now gone. I'll try find it and quote it. However there are other users who have been running for ~3 months and still have the buzzing, so this might not work either.

I'm going to keep burning mine in with D-Nice's settings and the slides provided. Maybe I can burn out this buzzing. I *think* i've read more success with usage than with replacement....but I could be imagining that too.

Below is some findings I wrote up in the Owners thread...thought I'd post em here too.

If we could pinpoint EXACTLY what happened Jamor, this could solve alot of peoples problems including mine. You are sure there is nothing else that happened to the TV or its surroundings. Would you be up to putting your old speakers back and seeing if the buzzing comes back? <3?

Using my ears the buzzing is many times worse in a line projecting straight out from the middle of the tv. Get off to any 1/9 of the TV that is not the middle ninth (think tick tac toe?), the buzzing drops off exponentially. The buzzing also gets worse when you stick your head behind the television and listen to the back at ~ 1 foot. However at that position it still is not as bad as the projection directly out the middle of the tv. The buzzing also does not decrease with distance from the projection that emanates from the middle of the TV.

I tried putting absorptive towels behind the TV to try and get rid of reverberations thinking that might be whats going on, but that didn't help. The sound is coming directly out the front of the TV or so my ears tell me. Stand up or lie down in front of the TV and the sound drops off to what I'd expect to be "normal buzzing". Sit directly in front anywhere from 1-15" and the buzzing is enormous. I believe viewers outside the direct front of the screen pick up on the back buzzing and its reverb off the wall, but its not as bad. They might be picking up on the front buzz too somehow. (I don't know the physics of sound.)

So SO strange. You think the buzzing of the power circuitry would not pass through the TV, but it seems as if the main power board in the middle of the TV is passing a bad bad buzzing right through the front of the TV.

Gonna pick up a new one either tomorrow or Monday. Right now I'm running the burn in slides trying to get the buzzing to maybe go away.

I also tried a UPS power protector thinking that might clean up the power. It didn't. At ~ 24hours burn in + 1.5 months usage, the buzzing has not changed characteristic. It ramped up to a level within the first week and stayed there. The power boards didn't change the characteristic at all! However from my best bet, its the main central power board where the plug goes in (and not the X/Y power boards) that is producing this sound.

My best bet would be the middle power board, but its the front of the board not the back and through the TV.

Camster can you try find out if yours is directional like mine?

Hi Marie!

I received my TV on the 23rd of December and use it on average about 7 hours a day so I believe I am passed the 100 hours but not 200 hours.

I'm not home right now so I don't know if there is a run time setting but I can check.

I did not replace anything on the TV. No new power board.

I don't know about the directional part - I was always in the middle and my TV sits about 2 feet away from the wall (square against/flat) so it most likely was reflecting off of the wall.

The buzzing was really loud in the middle and the upper left of the TV (when looking from the back). Upper right when looking at the TV.

I'm still trying to figure out what could have happened to reduce the buzzing so drastically. I did not change power sources, I did not change (or unplug for that matter) the power strip that it is connected to.

The only thing changed were the speakers. If I can find the time I will try and hook the old speaker back up and see if it does the loud buzzing again.

Sorry I couldn't be of more help and I hope you get as lucky as me.

I don't believe I'm in the clear yet. There is no way of telling if it could flare up again.

If I put my ear behind the TV, I can hear the buzz but it's not loud enough to hear even when my volume is low.

Before it was really obnoxious even with the volume on medium.

I did not use any break in slides or anything technical.

So is it perfectly silent? Definitely not. But it is no longer a disturbance and I have very sensitive ears.

Thanks Jamor.

I'm home now with a brand new 54G20 replacement from Costco. Another October 2010 build. .

Gonna start the testing I suppose. Watch a movie in the bad spot....see what happens. I'll move on to slides later I guess.

Whats troubling about the buzzing is it seemed to have gotten alot worse with time. At first I only got bad buzzing on white screens. Soon it was everything, even totally black screen.

EDIT:

Still buzzing. Just as bad as before. Same exact frequency and characteristic as before. Same combination of back and front buzzing, and changes due to content and power. It buzzes all the time too. On black screens. Louder on white screens. SD card screen. Luckily I've got some horizontal banding I noticed right away on this try, which I don't believe I had last time. (ThanYOU! Panasonic)

Running burn in slides again. If there was just SOME way to get rid of this buzzing. I don't want to go LCD. If its not buzzing its not being able to see the TV off angle.
It is SO directional. I put in almost 75 hours of burn in trying to get rid of the buzzing on the first one, going of Jamor's success. I'm back at 3 hours run time.

Despite my 1-yr warranty having just run out they were still able to provide some help. They had some local technicians come out to take a look and they diagnosed that one of the boards (the one in the upper-left when facing the front of the TV) needed to be replaced.

The techs came over and replaced the board yesterday morning and things seemed to be ok -- that is until I got home last night. The buzzing was not only back but was louder and this time seemed to come from the right side of the TV. I had paid the technicians $220 for parts and labor so rather than go back down that road again I identified where the buzzing was coming from by pressing down lightly on the case. Once I had a good idea I took the case off. I cut a kitchen towel in half and folded each piece and placed it over the board in the middle and over the board on the right. I screwed the case back on and voila - no more buzzing sound. Problem completely solved.

I'm not too worried about overheating as the towels aren't that thick and there are four fans in my TV but I definitely share jamor's concerns about having cloth near the electronics.

My question for the AVS community: Is this solution acceptable or is my tele going to go up in flames? Can anyone propose an alternative approach that's less risky?

Yeti. Can you keep us appraised on your fix? If the buzzing stays away. There are parts on those boards....you just laid the towel over the board?

Like others the replacement boards did nothing for me. Now a full replacement TV did nothing for me.

Okay, now that I found this thread, maybe I should share the stuff I think I've learned from my g20 and it's buzzing. I've got an 42" european g20 model, which does buzz so loudly that it can be heard to a normal viewing distance (2-5 m). The buzzing noise comes from two circuits inside the tv. Those circuits on my set are on top left and right middle spots in when facing the frontside of the tv.

Now that Panasonic has left out one layer of glass from their 2010 sets the buzzing of those circuits does come through the panel. You can hear it by muting your tv volume and putting your ear really close to the panel in a spot where you know there is a buzzing circuit on other side. My theory is that the intensity maximum (the poin or area where the buzzing is most loud) is in the middle line of the tv. By middle line I mean that you watch the tv in such way that your head is horizontally centered with tvs center spot and vertically in center or below that line. In that way I hear pretty loud buzzing with my g20 (and with the other g20 I've had, and with vt20, and v20 I've listened in stores). All these high end 2010 models have one glass layer less than the older Panasonic plasmas. I've tested this glass layer theory by covering the front of the tv so that this directional buzzing that comes through the panel cannot be heard anymore. Also, I've had s20, which has one extra layer of glass, and the s20 didn't have the same directional buzzing that g20,vt20, and v20 that I've listened did.

The other buzzing that can be heard to my viewing spot is the one that is reflected from ceiling and hard wall behind my tv. This buzzing can be eliminated by surrounding the tv from behind with materials that do not reflect sound so well. Though, it's pretty lame because then you cannot change the place of the tv and anyway, if you pay a lot for a tv you would expect not to need to do stuff like this :< This is my second g20 and both of them buzzed less in first few hours, but then started to buzz equally loud. I've ran the break-in slides with both tvs but the buzzing didn't get any less louder by time. Now I've got over 450 hrs in my tv and the buzzing has not been getting any quieter. I think that the only way to fix this would be to tamper the parts that are vibrating because of current generated magnetic fields or by calling Panasonic support and demanding that someone comes to do it for you. Or maybe if there is a possibility of getting these two boards replaced with ones that do have higher quality components that are insulated in a way that they do not cause buzzing sound even when vibrating because of magnetic field.

Awesome. I will completely agree with your directional center buzz at center and vertically below that point and the reverb off the back. Before reading your findings, I had come to the same conclusions about where the sounds were positionally the worst for me. As for the glass idea....I didn't know 2010's came w/ less glass. Interesting. As for replacement boards, the ones Panasonic put in my first G20, buzzing wasn't effected in any way. It was identical before and after. The boards appeared identical except for silicone applied to a couple coils on each board. Its also interesting that the boards you identify in your post are also the exact boards that Panasonic USA replaces. I believe there is no way out of this problem. People who have this television and buzzing are simply stuck. Others should simply stay away, unless they like buzzing or have a history of not hearing electrical noise. Of course there are those who don't have buzzing sets. I've tried two, they both buzz identically. I personally feel however, that some people are also immune to some frequency ranges of noise that is certainly marring some results.

Oh. I also feel exactly the same about the buzzing ramping up and holding. My first G20 did exactly that. My second G20 hasn't enough time yet to tell.

would like to chime in. october 2010 bulid 42g25. buzzing from components on back of tv. just bought the tv 3 days ago from 6ave through amazon ($782). called panasonic. they set up a drop off with a local repair shop. should i even bother? i love the pq. best i have ever seen. i can still return the tv. i dont want to, but the buzzing is pretty ******.

here is what i was thinking:

since sound bounces around (especially high freq), one should be able to glue a layer of some sort of soft foamy and porous material on the back cover panel inside the tv. not on to the components themselves (risk overheating), but on to the panel directly in front of the noisy component. this material should absorb much of the sound waves emanating from the component, thus reducing its chances of escape from the tv and into your ears. this will not eliminate the problem entirely, but i should be ok with a 50% reduction in the buzz.

i understand that we all shelled lots of dough for a product and it should work fine without us tinkering, but the tv is unmatched in many ways (especially for $782). i have removed the back panel and the my "solution" should not be difficult to implement.

what do you think???

It all depends. I don't know. If there was sufficient room this may be the fix. I know that you can buy PC Case sound dampening material that would probably work very well, but you'd have to find the right thickness to still allow airflow.

the rear panel is perforated up and down. on my tv i have no fans so it uses convection cooling (the heat rises through the tv and out the holes that are on top while drawing cooler air in through the bottom holes). the holes that are in the middle of the pannel are not as important as the ones that are on the top and bottom. i am thinking that a layer of sound absorbing material like acoustipack directly over the components glued to the back pannel on the inside should not cause much of a heat issue since none of the crucial holes (top and bottom) are covered. these products are engineered to work in extremely high temps. think of all the folks that mount the tvs inside their walls and cabinets. a little sound insulating material that is 8mm thick wont even come close to the temps that these tvs were designed to work in. besides, plasmas run much hotter than an other flat pannel technology.

You guys are nuts to do this to your plasmas. Risk of fire, overheating, lower life span, and not to mention complete voided warranty. O_o

I still have a loud buzz again.

I hate this TV.

I am so pissed off. I do so much god damn research on this piece of **** and only a very small percentage of reviews say anything about a buzz.

Why wouldn't any reviews have this noted? Why is this TV so popular? Who in their right mind would want a TV that buzzes like this and why aren't any reviews (especially the professional ones) talking about this?

I'm returning it and going LCD. Plasma technology is GARBAGE. Can't believe I got conned into buying this junk.

I thought I was sly and ahead of the curve. "Oh plasmas are cheaper because people think they burn in and have short life spans".. I must have found a hidden gem! 600 HZ how can you go wrong?!

WRONG. Plasmas are still cheap and no one buys them because they are still garbage.

The "plasmas are a hidden gem with a bad wrap" is such BS I can't believe I bought into it.

I am a sucker. Good thing I purchased through amazon. This piece of garbage is going back.

Samsung LCD here I come.

(BTW I'm probably so pissed off because as I write this the buzzing is annoying the **** outa me).

But how loud?

It seems some people can only hear the buzz if they go behind their tv and stick their ear next to the vent holes.

I'm utterly amazed that people buy these TVs.

Either I have a louder than usual buzz or I have amazing ears.

Nonetheless, I want to put a hole through it every time I turn it on now.

BZZZZZZZZZZZZZZZZZZZZZzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzz zzzzzzzBZZZZZZZZZZZZZZZZZZZZZ annoyed yet? BZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZ ZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZ ZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZ ZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZ


when I turn off the TV my ears are like "thank you james, thank you thank you thank you!!!"

I received a G25 a few weeks ago, and had loud buzzing as described in this forum. A tech replaced one of the boards, but the buzzing was unchanged. The tech also mentioned that the spray-on foam doesn't seem to be terribly effective, and that a lot of people have the issue.

So, I returned the G25 to Amazon and ordered the GT25 instead. The picture quality is amazing so I wanted to give Panasonic another chance. The GT25 buzzes much less loudly than the G25, enough that I'm not really bothered by it anymore. However, it still buzzes in a similar way. (Also, the picture quality is about the same). Whereas the G25 was loud enough that the buzzing was audible everywhere, the loudness of the GT25 buzz seems to depend on where I'm sitting and how I'm oriented. I can turn my head and have the buzzing go from audible to inaudible. I'm not sure what this means, although I speculate it could have something to do with the buzzing reflecting off the wall behind the TV. Moving the TV an extra foot away from the wall didn't seem to change anything though, so go figure.

Anyway, I've been reading this forum a lot over the past month, so I wanted to contribute my own experience.

Well I can hear mine on bright scenes from about 8ft-9ft away.... other than that your can't really hear it. Again, I have the 54G25 so I may be sitting a little to close than recommended sitting distance... but honestly once I tune out and focus on the movie it's almost a non-issue. I took the back off last night and the most buzzing comes from the board on the right hand side if you're facing the back of the TV.

jamor.

I'm so sorry. But i feel exactly the same way as you do. there are days i'd rather just put a baseball bat through the television than use it.

what are you replacing with? what model?

when you do replace could you either post in the G25 thread or this one (or PM me) a writeup of your comparison. what problems you traded? or maybe the Samsung LCD is perfect. thanks. problem with me is I really can't afford LCD/LED right now. going from a 54 to a 55 LED/LCD looks to cost me at least 800$ over what I paid for the Panasonic.

UPDATE: talked to the repair shop today. they said that there is a service bulletin out for this tv. the "fix" at this point is a sound insulating foam that they apply to the component/circuit card that will lessen the buzzing. the shop also said that if that does not fix it then step 2 is panasonic will send them a new component/board. i really dont care which method they use. like i said before, if they reduce the buzzing my a 1/4 then i will be happy. hope this helps some of you.

Hey goose - any idea on when the repair guys might be done with your set? I'm interested in how this might turn out. Also, when talking with the repair guys do you think there's anyway they'd give you a copy of said service bulletin, or at least give you the bulletin number#?

just got the call today that the set is ready for pickup. i will ask them to print out the service bulletin for me for "my records". i am not sure if that info is something that they can divulge. if i get it i will pass it on. i will be picking it up tomorrow.

*stares at thread*

O_____O maybe a plasma tv in my bedroom is not a good idea since i have really sensitive hearing....at least i'll wait to see what people say about the ST30 before deciding to get an LED or LCD. It sounds like a lot of people having buzzing problems isn't just normal plasma buzz but design flaws.
