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.

A buzzing noise coming from inside the tv but still buzzes when on mute but doesnt buzz when tv guide is up on the screen or when a channel is showing what time it starts


plasma tvs buzz a lot, depending on screen brightness. its probably normal but if you can hear loudly over your volume, may be a bad board or plasma panel. from behind tv, left side = y board, right side = z board, middle = power board ---- bad panel can buzz from anywhere... if you hear all parts buzzing, its probably normal plasma noise

Humming sound


Samsung states - A buzzing sound from your plasma TV is normal. It is caused by the electrical charges used to create the images on the screen. The buzzing, however, should not be so loud that you can hear it when the volume on the TV is set at normal levels.It is also important to determine the type of buzzing sound. A sound like a ground hum is completely normal. This buzzing can originate near the power cord connection or from the SMPS board position on the upper back of the TV. The buzz will be more audible as contrast increases on the screen, most notably when displaying an all white screen. If the buzzing sound is loud, you may have the Contrast set too high. Lower the contrast to reduce or eliminate the buzzing.You may also have loud buzzing if the rear of your Plasma TV is too close to a wall or other hard surface. Try moving your TV away from the wall until the buzzing is minimized. [1]
If the buzzing is at a higher frequency and resembles a crackling sound (like the sound of Velcro being pulled apart), and originates from the upper middle back of the TV, you likely have a failing SMPS board. Place a support call with Samsung to have the SMPS board replaced.FP-T5084 Have a known buzzing problem with a very simple fix.If the buzzing is coming from the left or right sides of the rear and the volume can be changed by pressing lightly on those locations, you are probably hearing the vibration of the grounding springs on the back panel. Call Samsung (or whoever) and have a technician confirm the problem. The easiest fix is to insulate the offending spring by applying some felt tape.

There clearly is a fault in the sub's amp section. It's probably the main part that does most of the work. It will need to be replaced.

Polaroid FLM-323B HDTV Loud Buzzing


Hi.

If your happy to remove the back casing of the the TV set.

Lay set face down on table with several towells laid out flat under it.
Undo all screws holding back on & lift it off you may need to remove tv stand to remove back.

Once back is off either locate speakers & unplug the leads from them remember to insulate the loose wires & tie them up out of the way.

Or trace wires from speakers to there plugs & sockets on main Pcb & unplug them & thats it.
Screw rear of set back on & ensure volume is set low or at zero.
