Polaroid TLX-04243B Horizontal Lines/Bars

[kevinm34232]

TV functions but with screen split in half horizontally and then to 4 horizontal quadrants, with black lines racing through. Reseated ribbon cables no change. Trying to determine if a main board, t-con, or panel problem..

T-Con: AUO 55.42T02.C02
Panel: T420HW01 V2

Ordered a T-Con board because not very expensive, just wondering if you guys have any guesses, have you seen a main board cause this?

Replaced T-Con board, problem persists. Ready to part out TV just not sure if it's main board or LCD panel causing issue... If I disconnect 1 ribbon on the T-Con board going to panel, half the screen vertically does same thing, the other half is steady white with some vertical colored lines. Not sure if that indicates anything..

Anyone know how I can determine?

That does not sound too promising.
Can you include pics of it?

To be on the safe side, check voltages and regs on the main.

What's the panel model?

Oh sorry about the panel number but I meant pics of the half screen with white on one side.

If you care to, I have found the panel for 150 (not including shipping).
