Just picked up a Marios Brothers pcb non working, when the game is turned on all you get is a blue line down the side of the screen and a sound that sounds like a squeaking door opening. The sound sometimes will just keep repeating itself and other times just make the sound once. Doesn't coin up and pushing the test button doesn't do a thing. tried to reseat all the chips but no luck. Anyone ideas?
