LG OLED TV vertical line
Hi. My OLED LG TV just recently started flashing a green vertical line on the screen. I suspected water damage because I cleaned the TV screen 2 days ago with windex. I opened the back and reseated the ribbon cables from the tcon board and placed a heater on it. Now the green line is gone and there are black spots left in it's wake. They function normal on certain colors but are black on mainly light blue and green.
ANSWERS:
"Given the change in behavior after the re-seat, I would still suspect the ribbon cable or connectors. Try cleaning hte connectors with alcohol. just flood the connector a bit and let it dry. Wipe off the ends of the cables as well with alcohol. Re-attach the cables and try again. This MAY resolve the problem. It sounds like a connection issue at the moment and not a problem with either the T-con or panel. If the cleaning does not resolve the problem, I would start by replacing the cables. This is the cheapest option with which to start.
Dan"
