Complete noob to working on TVs. What I'd like to do here is simply figure out what board to replace as I don't think I'm up for replacing individual components. My son has a Sanyo DP26649 I bought used and I liked it because it has a lot of different inputs for game consoles, PC, etc.
Randomly, the TV screen will glitch for a brief second as well as repeat the last bit of audio that was playing. It just lasts for a second, then the TV will "restart." It never loses power, but simply goes black and a few seconds later will return to normal. On a rarer occasion the TV screen will stay black and not react to the power button being pressed, meaning it has to be unplugged and turned back on to resume use.
This started as a rare occurrence but now it can happen pretty regularly every 10 minutes of use. This happens independent of what inputs are being used (HDMI, Component).
As a sidenote I notice my son had the extra yellow video cable from his Xbox 360 (not used for component video) wrongly plugged into an audio output. No idea if that could cause damage or not.
I'd love to figure out if I need to just replace the main board or something else so that I could get it ordered and here before Christmas. Any help / directions would be greatly appreciated.

I don't know what to test for voltage or what a linear regulator is, but I'll be glad to pop this thing open and post some pictures or follow any other directions.
