Thomson 46FT5453 LED TV vertical / horizontal dashed lines

[dicky96]

Hi guys
I have this Thomson TV here

Strangely there is no model number or any other numbers on the back of it but 46FT5453 could be the model number from a sticker on the main board

It has two wide bands of broken vertical lines on it.

Disconnecting the TCON cables just makes that side of the screen go blank (no lines) and does not affect the other side

Is there a way to determine if this is a panel fault or some other problem, without having to order another TCON or main board just to find out?

It has tab bonding boards on the bottom edge of the panel, so more likely the boards may have been damaged by cleaning liquid, you need to inspect the tab bonding boards.

Try the "Tape cut-off" method, you just tape a bit of the ribbon cable on the bad side, blocking the bad signals, if it clears up, confirms panel fault, most get a good picture, sometimes you have to play with how wide to make the tape.
