This is my friends Firepower but it been in my game room for the last 15 years. It has been working great for years without a problem but last year it developed a sound problem, sound would come and go. Not to long ago it blew the solenoid fuse so I finally got around to open it up and replaced the fuse. It also had a dirty switch in the ball hold lane. I cleaned all switches and the game fired up and played, even the sound was working but soon the sound crapped out again so it was time to figure it out. I took the sound board off and the pins for the AC voltage input had bad solder joints so I de soldered and re soldered the pins and put the sound board back in and turned the game on and the 2 fuses on the sound board lit up like a Christmas tree bulb. I pulled the sound board back out and checked the rectifier and 2 of the 4 internal diodes were shorted so I replaced it and wile I was at it I also replaced the 5 volt regulator. Put the sound board back in and Firepower fired up and was 100% working again. I played about 12 games in a row with no problem and I left it in attract mode wile I worked on other stuff in the game room. It had been on for about 2 hours every so often it would say Firepower or make some noise, sound effects, normal stuff then I heard a solenoid fire and started making sound effects. The game had kicked a ball in the shooter lane but it looked like it was still in attract mode, still flashing the hi score like normal. The flippers were energized and work but all the solenoid were dead and no targets score. I checked and the solenoid fuse F 2 had blown. Now Firepower blows the F 2 solenoid fuse on power up and kicks a ball in the shooter lane. The game appears to be in attract mode but the flippers are energized and work. I put a 2.5 amp circuit breaker in place of F 2 and if you reset it wile the game is on it kicks another ball into the shooter lane and at the same time it also fires the return lane kicker and all 3 out hole kickers. I am not sure where to start next, maybe its a bad interconnect between the MPU and solenoid board? I figured I would ask and see if this is a common problem. Here's a short video showing the problem.
Thanks.
