I have an LG plasma that after reading through a bunch of posts and doing some testing I believe has a bad YSUS board. The problem is that that doesn't make sense to me for some of the symptoms. The problem started yesterday. While watching a movie the TV just shut down like I pressed power. I have it hooked to a PC and use RS232 to turn it off and on so I thought maybe something had glitched there. I turned it back on and finished the movie with no problems. The same thing happened today so I checked logs to see if something in the control glitched and sent an off command but it didn't, After... -

ZSUS was replaced: 15v missing.
Any help will be appreciated... -

If I remove both tabs from ZSUS to screen but keep all other connectors to ZSUS on then TV boots properly but screen very dark without ZSUS output, no ticking from ZSUS. So it only shuts down when under load from screen.
If it is ZSUS then how to fault find, I already looked for shorts. No transistors shorted or caps and its...12-13-2017, 01:18 PM -
