All of the optos quit. This has been a constant problem. They all work for awhile then they all quit. I am just stumped. I have switched out the CPU Power board and opto board with boards that I know work and still nothing. Im just stumped.

all. even the trough optos? You've checked 12V power obviously since you swapped boards. make sure you are getting power to the opto board under the playfield consistently. Probably a pinched or bad jumper wire.
know for sure the crane optos the underground optos the car optos and the multiball/extra ball shot don't work. the trough ones must be working cause it knows how many balls are in there.

All that is controlled by the board listed above probably needs c1 replaced , that be a cheap fix to try
Quoted from joekiss:LED on the opto board and both trough opto boards are bright red.
Trough is fine as they are separate from your issues , but im guessing the 7 opto board cap is leaking or dried out .

Check all these connections alsoScreenshot_2015-05-26-01-19-49.png
CPU power and the opto under the PF. Actually put bthem in a different machine and they all work fine. Its GOT to be a bad connection somewhere that comes and goes. As I said It quit working then worked for awhile now its not working.
There are three small connectors (i believe 3 or 4 pins) at the bottom left of the driver board that power the optos. One could have come off. but again you need to use a DMM and check the regulated 12 volts at the driver board. If you don't know how to do this, you need to find someone that knows how to do it and show you with their meter.
I have a meter I just don't know how to see if a connection is complete. This machine has all of the crappy IDC connectors-about to just start repinning.
