Wow, not even close. Since ajapel was getting a game screen (followed by bad console output), I believe the TV was catching the signal just fine. As already suggested by others, I suspect the power switch or its solder connections most strongly. This would be followed by: the power adapter, power jack or cartridge port. Finally, if all of those can be ruled out, it could be a bad chip in the console but IMO this is unlikely.
I've cleaned the power switch. It looks fine but I'll have to take it apart I'm guessing. When the game pops onto the screen, the sound also comes with but after the second, both usually disappear to black. I've never soldered but I'll find out what equp to get and give it a shot. I have a feeling it's something simple since it seems to intially work.
Thanks for all the help.
