Samsung Ln46b650t1fxza horizontal black and white lines vertical colored lines

[withalligators]

Hey folks,
I'm pretty rusty and I've never seen anything like this, not sure if it's a really far gone case of bad tab bonds or if it's a fixable tcon or main board issue. Screen turns on with a black screen and chime. Faint white horizontal lines appear at regular pixel intervals and fade in. Where the white lines are visible, there are multicolored vertical lines. Any ideas?
If I can get this working, it's a donation to a friend who's kid broke his last TV.



Thanks
Alex

Do the lines remain in the same position each time you switch on because if they do, it is probably a Tab fault.

Yeah, they do. I have been in the field for week, so haven't really been able to play with it, but i believe you're right.

Seems like panel to me. Try messing with the Tab bonds see if any of them ade causing this issue.

I suggest replacing the T-CON Board.
