Some lines can have no influence, the lines to be blocked are the clock lines usually are 8 but can be less, check on the screen's small boards if there are test points named CKVxxx you can also discover to which pins are connected by using multimeter..

Dude ! I have found the test points, called TESTa12 TESTb12 . How can I test them? Can you please guide me ? Thanks

LE: unfortunately these are not called CKVxx

And how can I find them? I mean, there are no markings on the small boards, just the capacitor numbers C- etc

no you' ve not understood, the faulty part of the screen is the right part, so you have to put tape only on right half and not so, you start from far of side and shift 1 pin per time only not 8.. but only 8 pins covered..

Ok, I will try. But can you have a look at this video and maybe explain why he has covered like 15 pins at once please?

I am afraid I have only removed the u ribbon from right side as I ran out of time to do so for the left side aswell

I will try this tomorrow. So patch 8, then another 8, only from on side of the u ribbon, until it gets fixed? Please look at picture.

show us clear photo of the left side panel puffer boards when u look on it from back side

First two pics are from the left side of the tv as you look from the back ( right side front)

Last two are from the right side of the back( left side front)

I hope when you said puffer boards, you meant this.

No it's not you Gbb, it's that goofy guy that keeps crying panels shorted every time he sees a line or two, which it could be a bad panel but could also be a LOT of other things as well, we all know his name.

I completely agree with you, but there's nothing else I can do but try things. So far, the only thing that worked was changing the MB, now I got back to having an image. I would also change the caps on the lower boards where the the flex ribbon connects, but honestly I don't see which caps are they or the name, so I can order some.

Like the one in the pic

Despite what one member says, lines on the screen even lots close together doesn't instantly mean a bad panel, it could be as simple as a bad cap on panel driver boards which technically is a bad panel, or cap on mainboard or cap on powerboard or something else on one of the boards, those who jump to conclusions quickly, NEVER make good troubleshooters.
