Hi All,
I just joined a few weeks ago with a Count-Down. It's given me nothing but trouble!
Starting with no key for the back box. Had to break in....that was fun! Then I replaced the lock, but with the head locked, the nut on the back of the cam fell off, so I had to break in a second time! Oh, yes, the third time was when the door closed and the bottom hook dropped on it's own.... I'm getting pretty good at fishing with a wire hanger.
I've re-pinned the connectors, fixed an issue with the power supply, re-faced the drop targets, cleaned acid damage to the MPU and replaced a few IC's, even though I think they were good, cleaned switches, pf, cabinet etc., rebuilt flippers and probably some other stuff that escapes me now.
The main issue(s) right now is(are) that the blue drop target reset coil locks on, while the other drop target banks won't reset. I've checked transistors, they appear fine. I even bought a replacement MPU, but that didn't fix the problem.
Any thoughts where to look next? and does anyone need a replacement MPU? If my original is actually good, I'll either keep it and sell the new replacement, or keep the replacement and sell the original, not sure yet. 1st have to get this beast working.
Oh, does anyone have a Count-Down back glass to sell?
