Got this one from a fellow Klover , and not quite sure where to start on it. Gave the board a look over, and found a bad cap, but that was it.

Game is very dark and only showing red. Game will coin up and the sounds work fine. Problem is the graphics don't move. Gfx freeze but the sound and play continues. Can play the game "blind". Rather odd.

Any suggestions on where to start?

Have you tried putting it into test mode? Sounds like it's some fundamental logic problem to be honest, but always worth trying test mode, just on the offchance.
 
Test mode will come up, but then it freezes before I can make any selection.
