Hitachi 42" Plasma HDTV

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.

Vertical lines on screen ?? 3. If yes ..?

Sounds like a bad component on the video board. These days, TV techs just swap out boards for whole new ones.

I think you have problems with the digital main PWB.

If the power PWB failed, turn off and change the pilot ligth to red.

vertical red line on screen - I have a Hitachi plasma 42HDs69

somewhere in the tv menu there is a place to make video adjustments. one should be for aligning the color guns. one is for red and the other two are green and blue. it will give you a cross in the center of the screen. it should also give you prompts to adjust the lines for centering and to save changes. this happens eventually on all rear projection tv sets.

1. Check D725
2. D707
3. CK03

I had recently noticed the same thing happening with mine.Then the left half of the screen turned black and has various red, green, and blue vertical lines. The right half of the screen shows has the picture just fine. It's exactly right down the middle of the screen.

IF THE LINE IS ABOUT 1INCH WIDE THE CHANCES ARE IT WILLBE YOUR PLASMA DISPLY THAT HAS GONE . WOULD BR CHEAPER TO BUY A NEW UNIT . HOWEVER TRY RINGING HITACHI EXPLAIN THE FAULT COMPLAIN THAT IT SHOULD OF LASTED LONGER THAN THE WARANTY AND SEE WHAT THEY WILL DO ABOUT IT
