Sanyo TV FW55C46F with white vetical lines same place and image exists

[pharmadrahmed]

I've those vertical lines in fixed spots ( don't move or flicker or change)
tcon board by Lg looks working, voltages are normal. cleaned all flat cables and sockets.
even withe t con board disconnected I still get those lines on the white backlight background. is it a defect of the panel itself? can it be fixed?

try squeezing the bezel, NOT the screen, where the lines are, see if they change any, seems like a bad panel.

Find the bad spots on cof and get something like surgical tubing to apply pressure to the bad areas.

I tried squeezed the cable at the connection with the board, No change at all in the picture also tried all the 4 connections on the 2 boards. all connections look good. It's not a connection problem between the panel and the board. it looks like the panel had liquid pour because I found few residues inside at the back of the cof. Is there any hint?

ah, ok, another case of people putting liquids on the screen in excess, you really should never need to do more than dust the screen with a feather duster twice a week or so.

If you can't make it work by applying pressure, your screwed.
