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.

Fuses F5 & F7 blown. Replaced with circuit breakers. Both blow after a few seconds. Unplug J6 & J7 and they don't blow. Leave J-7 connected, F5 blows, but not F7. Same in reverse for J-6. What I've noticed different than originally is the GI now comes on for only a second or 2, then goes out, unlike when this happened a couple months ago(just getting to it, it hasn't been working these last couple months)when the GI stayed on. Also if I leave the machine on for 15/20 seconds, all the solenoids start to "vibrate", before locking on. Throw the off switch, GI & Display flash on.
