I purchased a working Funhouse with an MPU that had batteries leaking onto the MPU.
I removed the MPU, cleaned the board several times...replaced at least two small caps (470) and a few resistors. Put new batteries in the holder that is pretty much toast! It will not start a game.
I am assuming a broken trace or another component is the problem...however, being a newbie...can't locate on the schematics where this might be affected...
