My LG50PY2DR lost video, but the audio is OK
While watching the TV I heard a pop then the picture went out, but the audio was fine. I was told by a friend that either ZSUS or the YSUS board needs to be replaced, how can I figure out which one needs to be replaced.

There are fuses on each board, they're ceramic, so you will not be able to see if they are blown physically, you will need a multimeter. Only one is normally blown, that will be the board you will need to replace
You need to check the Y-Sustain (Looking from the back, its the board on the left, connected to the upper/lower scan PCB's), the fuse should be close to where the power supply is plugged into.
