Re: LG Flatron 47" Turns on for 10-15 seconds then screen goes black

I tested the video board to see if it had power, that was good. Decided to turn it on, and it was working while the monitor was leaned forward. Moving it made the picture cut out, started jiggling cables and the port on the T-con board is janky. But I got it to work and keep a stable clear picture for the time being. Otherwise a new board will be in my near future I suppose.
Thanks for the suggestions

**Edit**
Sorry for not using the proper picture etiquette.
Took a vid of the monitor turning on, ignore the background chit chat w/ my drunk roomate.

Here's a short clip in the dark showing the backlights being on

That's all it'll do, turn on, backlight turns on, but the menu won't display...

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....
