Hello guys,

I'm pretty confident that I have a bad mainboard ([URL="https://www.badcaps.net/forum/showthread.php?t=41584"]https://www.badcaps.net/forum/showthread.php?t=41584[/URL]).

Not at home right now, but I can. The TV has like 4 HDMI ports (3 on the back and 1 on the side) and the particular port used made no difference in terms of this problem. Does that change your opinion as to what my first step for troubleshooting should be?...

Hello. First time poster (2nd if you include the introduction post) here. Mechanical Engineer by trade, with a very basic/general electrical background. When it comes to TVs/Displays, I'd consider myself a layman but I learn quickly and understand the basic concepts.

We currently have an HTPC connected to an LG42LD550 via HDMI. The other day the TV lost the signal from the HTPC. Thought the computer just needed to be woken up or restarted. When I restarted, I'd get through the BIOS screen (there were a few pixels that should have been black that were flashing green along with some...
