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.

SOON AS I TURN MY TV ON IT SHUTS RIGHT BACK OFF


It sounds like a repair is required, but to confirm:

With this model, you can try unplugging from the wall for at least thirty seconds, then plug in and switch on. (That's if you haven't already).

If that doesn't work, there is a fault causing the power supply to self protect and shut down again. Repair will be needed.

Hitachi P42H401 turns on then shuts off seconds later


its most likely the common hitachi fault....its a little resistor that burns out, it happened mainly on the old crt tv's. any tv repair shop should be able to sort it for you.

Remove base from television


Remove 2 screws on the back bottom by the stand.

Remove 4 screws, two on each side about 3/4 of the way toward each edge.

Pull TV up to remove from stand. Put plate and 2 screws back.

Can see this if you download the manual from the hitachi site. Just do a search for the model no. on their site's search engine.
