My 42'' LG Plasma TV (RU-42PZ71) recently started to malfunction. After a 3 second turn on time, the screen displays a vertical bar of multiple colored noise on the far right of the screen for 4 seconds, then the bar begins to move to various locations on the screen. This is repeatable as I change the video input. The TV tuner input behaves differently, the entire screen shows the multiple noise color. I can not display the menu or any other information on the screen.
I was told a ''power supply'' was the issue, not sure what board? Any help would be appreciated. Here is a list of boards in the TV:
Main PS: 3501V00182A
YSUS: 6871QYH029A
ZSUS: 6871QZH033A
All fuses checked out ok.
Thanks,
Alex
