Looking for some help here. Was watching TV, then screen showed vertical lines...then wen to black screen. The sound works, it connects to the internet, and the back lights are on. The TV seems to be attempting to show picture because I can see the screen lighten and darken to respond to whatever's playing . Just no picture and black/gray screen.
I have tried to replace the TCON board. It didn't work. I even tried to replace the main board, but it showed the same issue. Anybody had an issue like this or have suggestions?
