Most likely cause is failure of the lower buffer pcb.

If picture only one side or only top or bottom set uses two boards to drive the screen, either one of them is bad or the actual display panel itself--it is the entire screen unit where the picture is displayed.

Maybe a tuner problem--considered hooking up whatever you use for signal to the rear av jacks? bypass the problem?

LG 50PC5D rigth screen colored lines 12''


LG 50PC5D-UL Plasma TV.... While playing XBox360 the screen just shrunk to the top 3" as though some one was holding a towel over the bottom portion of the screen. I have unplugged all inputs and the unit. I have let it cool down. Still it remains in this condition. I can't see the menu because it's in the portion of the screen that is "blacked out". What do I do?

Multi coloured vertical stripes on plasma screen


With half of the screen working, and with a Plasma tv. I will look at the driver board as being bad. Take the back cover off, the driver pcb will be at the top or bottom of the set. They are only about 2 inches tall and will cover most of the lenth of the set (2 boards that run end to end). The board that is on the side of the tv that is bad is the bad board. Replace that board or have a tech replace it.
