Line, faults & possible causes to LCD & Plasma screen are given with illustrations. You can get an idea about the fault to an extent.

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.

You are proberbly using RGB leads, wich is red green blue, each colour runs through each cable, have a look at your cables maybe one is loose, or damaged. check on both ends, but the cables MAY NOT be red green and blue, but the terminals that the plug into will be.

1. Frist on the BURN MODE.
2. Check whether same
Vertical lines on screen ?? 3. If yes ..?

I had the same problem with my Hitachi 42edt41. It was the Y sustain pcb. Large board on the left as you are looking at it from the back. Costs about $750. for the part.

color syncronization problem...

Convergence Amp IC issue....originals are STK392-110..replace
W / upgrade Stk394-160E Hitachi part # CZ 01341 and check nearby resistors for overheating............................T.

I have had this problem in some models of plasma sets before. In most cases the power supply and main drive boards had to be replaced. In a small number of cases the failure was the screen itself.

In all cases, the cost of the repair was expensive. For the screen failure, the set was scrapped.

use the advanced options page and reset the factor blue and red convergence defaults then do re apply the auto color defaults color at first it seemed very red (which is good because red was the missing factor in the green picture) but after reseting all the color and tints to the normal ranges I then reset the color auto correct again and all seems fine.
