Hi guys as you can see on the picture I have problem with this tv there are some vertical lines on the display, so the problem is t-con board or some short on the board of the panel but I don't know where to start. Thank you for the answer! Ah I never doing some tests for this problem, any help is welcome Thank you again

Hi thank you, but it doesn't explain anything about t-con board but only power supply board.

Oh I'm sorry for misunderstanding and thank you for your reply, in the meantime I checked some things and with a temperature laser gun (I don't have a termal camera) I found a side (marked with white colour)with the temperature growing up about 60/70-75
Maybe is that component the problem?thank you again.

Maybe try cleaning the 2 tcon ribbon cable pins with ipa, some use pencil eraser, not too vigorously they can be fragile, inspect and make sure none of the pins are damaged and make sure the lvds cable is clean and secure at the tcon, maybe try a replacement tcon, they usually aren't too expensive.
