PSone Screen Problem!

[Trollman]

I hooked up my PSone screen to my Gamecube, and it worked great if I didn't have a disk inserted and was just playing with the console settings. However, if I put a game in it the screen will dim and shut off after 30 seconds. I still have sound and control, but no video. I know the composite video wire works fine, but still can't find the problem. I am using a 7808 regulator, if that helps at all. I believe it may be the graphics card overheating; does that sound accurate?

Can a moderator lock this? I fixed the problem.
