Sorry...let me clarify things. When the game goes out, it's just a black screen with either one, or sometimes four or five flashing symbols that flicker in many different colors. I can't play the game, hear it, or put credits on it.
I couldn't play it at all yesterday, so i imagine it's fried for good. I turn on the machine and it just automatically goes to the black screen with the flickering symbols. They aren't numbers or anything, it's mainly the flashing fruit symbols. I was reading something that says there's a 'watchdog' chip in those Ms Pac games that will freeze the game if something's going wrong...could that be it?
The original guy i bought it from says it 'overheats' and that's why it glitches out after a while of playing and that it needs a new power supply. Is that possible? I'm thinking more on the lines of that a chip went bad and the guy just assumed it was overheating and never had any concrete proof. However, if i get the chip fixed, is there a chance it could overheat? The board got pretty warm when i was playing it the other day, but, since this is my first game, i'm not sure how hot the boards normally get. And is there supposed to be a fan inside? My cocktail game has a fan inside it, but my upright does not, could that be the problem? Thanks for the input guys.
