Plasma TV with half screen white line


Standard Member
Hi everyone..I'm hoping someone can help me here. I have no experience on plasma TV's but recently inherited a "dead" one. Turned out (electronic engineer here!! that one of the 5V lines was down. Repaired it and the plasma sparked into life......well nearly......about 1/4 of the way from the right hand edge and going up to the centre of the screen, is a white line, about 1cm wide......almost like a section that's not being driven. Or is it a knackered screen? Please can someone tell me. I've attached a photo (I hope) so as you know what I' talking about.....any comments welcome. Thanx in advance.

Hi - The good news is that its definately not your panel, otherwise you would get a noisy bar from top to bottom. One of your driver boards has partially failed which controls the lower half of the screen.
