Verticle lines on Samsung PN42A400 Plasma TV

[xNOTx]

Hello 👋 I have a tv with these red lines. I've tried cleaning and re-seating the ribbon cables but no luck! Tried all 4 on the LJ92-01485 board and on the bottom of the panel. Do you guys think it's the board?|

It's not a board. Generally unfixable thing as far as I'm aware. Sometimes you can push on a cof cable and it'll make it disappear

Yup I've tried touching them, moving them, re-seating and cleaning. I'm thinking there is another cause, and not an issue with the screen. But I could be wrong.
Weird thing is that it looks like they are both at the same distance from the side of the screen. Also they look like they are between pixels.

Oh, is it possible to swap boards with different revisions? IE: LJ92-01485A <-- B, C etc

I'm telling you, swapping a board isn't going to fix this. This is a panel defect. But who knows

spray freezing air on the bottom ribbon cable next to the bad line.. you can.also try hot air.. not.a.fix, its a test...
