First post here. So I found this 47" monitor with the intention to fix it. The screen turns on, then after a few moments it'll have lines appear in the screen and then go out. Once it goes out, not even the menu screen will appear. So that rules out the external device malfunctioning or the cable (xbox/hdmi).
I've examined all the boards for blown caps, didn't see any(or anything blown).
I'm leaning towards it being bad inverter board(s) after reading the symptons. I just don't want to buy $80 worth of boards without somehow testing them to be sure that's the problem. So that's my mian question, how would i go about testing these specific boards? I couldn't find a wiring diagram online about them to know the pin outs and specs
The picture I first got, looked clean and crisp.
Model number

Power board

T? board

that one board...

Master inverter

Slave inverter

Thanks for the help,
Joe
