Quoted from AntennaMan:Have what I thought was an immaculate Tommy, never a problem, then suddenly when I turn it on the propellers constantly spin, can't start a game and the DMD is out along with some of the lighting. When I turn the machine off, all the "dead" things, momentarily flash on, so I know they're not really dead. This happened when I played a couple of games, went to the office for a while, then was heading upstairs and decided to play one more game. Anything specific to look for when the propellers constantly propel?
Rebuilt the power supply, because the +5v was only +2.2v. I replaced all caps, the voltage regulator, bridge rectifier & power transistor. On restart all solenoids except the left kick out were out. Replaced the blown fuses tied to them. All appeared to be well. Played a few games, no blinders. After the rebuild I ran through the tests, but didn't know what the Arch Test was, but now I do, still no blinders. Before the rebuild, when the +5v was running about +2.2v, the propellers, mirror and sometimes blinders were operating on their own. Blinders have never been a problem. Am I possibly missing the fuse controlling them, which I can't see any specifically listed in the manual or is it a transistor or something else?
