More testing done ...
The solenoid test goes through most of the solenoids in the test cycle (Click 3) - but doesn't do the flippers and the ball eject (start of play). Strangely, when the machine has been newly switched on after standing, it works fine, but then seems to keep on resetting the drop targets and doesn't eject the ball on about the second game. I have tested the switch for the "ball start eject" solenoid and that was newly replaced and seems to be working fine.
Lastly - there are no sound effects (the no 8 dip switch is set to on). It was making weird sounds after transporting it to my house and I shook it a bit which caused the weirs sounds to go away - now seems to taken everything with it. I have fiddled with the speaker volume in the main box and that seems to be OK. Are there perhaps some know issues with CP sound?
Any suggestions as to what to check now GREATLY appreciated - I'm stuck (just like the continuous drop target reset and no ball start eject) ................. TIA
The flippers are not part of the solenoid test. The ball kick is part of the test and I find it strange that it does not work during the test, but does work for the first game. It almost suggests that there is a dry joint on the Solenoid Driver board, or a connecter problem to the solenoid Driver board. Can you remove the SD board and reflow the solder joints on the connectors ?
The sound problem - I have not worked on this game for a long time - does it have the ribbon connector from the sound board to the MPU board ? Reseat the connectors to the sound board as a start.
