hiding under your bed

Hey guys, I've got a DMG with a few issues and I'm currently away from home for a couple days without tools, so I figured I'd ask you guys if you've experienced any of this crap so I might be able to get it fixed sooner when I do go back to my apartment.
First thing I noticed was that the contrast was a little... off. I can't get the screen to go completely black, and if I turn the contrast the other way, everything fades out before I've turned it all the way.
Second, the system seems to be registering that the A button is being held down. (ie: I boot up lsdj, try to start navigating the song screen, but it just changes the number of the currently highlighted chain because the A button is permanently being held.)
And third, if I press in any direction on the dpad, the screen fades out until I let go of the button.
Does anybody have any idea what would be causing these issues?

Sounds like your ribbon cable is damaged. Try a new one or change the front PCB altogether.

Damn, I was really hoping that wouldn't be the case.
