Your capacitors are bad in the TV. http://www.badcaps.net/forum/showthread.php?t=425 They are really easy to replace if you have any experience with soldering.

A local cable or satelite receiver or set top box or video may be causing interference - turn off all the other devices and see if the buzzing clears. Energy saving lamps can also cause this.

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.

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

If the sound isn't coming the speakers then its cabinet expansion. Specifically between the panel and the front cabinet.
I believe Panasonic has a fix for this.
