Hi

If you can hear any buzzing from more than a few feet then the TV is defective and needs to be replaced. Buzzing is a common defect among plasma TVs regardless of brand. It has nothing to do with the plasma cells working; usually it's a defective board or a power supply problem or something like that.

Also check this related article in the given link to get a detailed idea:-

SOURCE: sky 42 inch plasma tv

hi all .ive had the same problem,a thick black line down screen.sometimes it flickers from top to bottom and other permantly in view.but i have solved it.forget your ic boards and taking apart tv.have you got either a ps3 or wii connected to tv.if so unplug power lead from socket and relocate in seperate socket.make sure the lead is completely free of any other leads and you might just find this works.i think the power lead creates some sort of frequency that the tv picks up .good luck hope it works

You will take the video out and audio out from the tv, plug those into video in and audio in on the vcr, then put the channel on the vcr to line in, if your using the front, it will say front. Don't forget, DO NOT change the channel on the tv nor shut it off while recording this way or you won't have a recording.

Loud squeaking coming from left rear 98 Ford explorer

A squeek would indicate a sound that is not always present. A squeel would indicate a constant high pitch whine. If it is a squeek you need to check shocks and grommets. If it is a squeel you need to check the brake system and the bearings

Panasonic th-42px600u high pitch sound

likely a coil or small transformer in the set is vibrating hard enough to make it squeel, it would have to be located with back off by listening to see where it comes from.

cure would be to replace the entire board it is on or hot glue the part that is causing this to dampen the sound.

If it is coming from the front screen unit that is a more serious issue.

I have a 42 inch Hitachi plasma tv that is making a very loud static noice coming from the internal speakers. It stays at a contstant very loud volume unless I completly mute the tv or turn the volum

Based on what you have tried if a buzz or loud static via the speakers you have something wrong in the audio output circuit of the set--problem here is that circuit may be part of the Main board that processes all signal---a look inside---following the speaker leads back would lead you to that board.

A simple thing to do to narrow it a little (you may have done this) is with sound all the way off put your ear to the internal speaker--hear anything at all like a deep hum?

Depending on age of set and cost of the board likely bad it may or may not be a do it yourself repair.

High Pitch Noise on 42" PLasma Gateway TV

how old is your plasma TV? try check the switch / volume of the sound settings.. Sometimes, when you always increase the volume, it will tend to alter the limit of sound and causing the sound to provide sound undesiredness. I suggest to check it with a liscensed technician.

Loud buzzing

check your connections again, if you have the audio and video reversed you will get this exact problem no video/ fuzzy video, and squealy noise out of only one speaker (other will likely sound correct) You're watching the sound channel, and listening to the video channel basically... hehe
