Vizio SV420M green vertical lines

[tibimakai]

It's been a while, since I have posted here.
I have got this TV, from a coworker for free and I'm trying to repair it.
I have replaced the T-Con board, since it was a couple of bucks, but nothing changed.
I'm measuring the voltages and they are all there.
Removed ribbon cables, re-inserted them again, with no change.
Any ideas, what else can I try?

I'd change the main board.

I suspect the mainboard as well, but it is not available, or it is over $100 which is not worth it.
Do you think, that it would be a bad/old capacitor?

have you tried different sources ?

Re: Vizio SV420M green vertical lines

i doubt it, but you could easily find out by heating up the caps. just for heck... flex or squeeze the frame a little

Didn't try different sources. You are thinking analog source?

I have tried only HDMI 4. The menu has the same issue as well.
