Hi, My Stellar Wars plays fine for about 4-6 games. then the S and R drop targets will quit registering. If I shut down the game for 15 to 20 minutes, and restart, it will play fine for some time and start not registering those two drops again.

The only thing I did to the game before this was replace the diode to the outhole switch. Somehow this diode broke on one end of the plastic towards the non-contact side of the switch, so I assumed this is where the band was because I replaced the diode with the band towards the non-contact side of the switch.

I do not know if the diode would happen to be in the wrong direction if that would cause this problem?

Any ideas where to look would be greatly appreciated.

Anyone?

Thanks for helping out. The S&R you are referring to are the roll overs. The S & R I am referring to are drop targets S is in the lower left bank . R is in the upper right bank.

I'll check out the row 1 switches and let you know thanks

Still can not figure it out the two drop targets in question are 16 and 32, but the diode I installed is on 9

Mine is not scoring any points or making any sounds when hit, and like I said, if I turn the machine off for 15 or so minutes and start it back up it works, I don't know what or if something would be over heating for some reason.

That's my next check I rebuilt the center ones guess it's time to do the other two

I have not had time to clean the drop targets yet. Bad weekend for working on it. another thing going on now is it Tilts for no reason, never on first ball, but the remaining two will tilt before the ball is shot. I work on it this week and report back.

I put in the rest of my replacement boards for my drop targets that I purchased over a year ago, played a few games and it appears to be working correctly.

Not sure about oiling contacts, I leave mine dry.....
