I've been in contact with someone with a solid Ms. Pac cab non-working for $100. I just thought I'd check here to make sure it's not a super expensive fix. He says it got random garbage on the screen and then he messed with the coin mechs and it got white dotted horizontal lines onscreen. He then reset the game and it got letters and numbers, then reset it then dotted lines again. Anyone have a clue what is wrong?
