Do you know for sure if the replacement optics are good?  You can go into the self test mode (input/output tests) and test them.

Follow the directions here to get the SP chip number (unless you know for sure what is in there). This will help to give the right self test directions.

Here is the PSR for the SP1271. Go to the group 3 input tests. There you can test the coin A, B and C optics. Let us know what they show.

It sounds like you did it right.  While on each of the tests (10, 11, & 12) slide something in where a coin goes to break the beam (a strip of cardboard works well).  They should change from 1 to 0.

It looks like the coin in C optic is bad, as it shows 12 0 for you without something in there to break the beam.  It may just be dirty or have a dust bunny in there, but if you just changed them, probably not.

I would try the test with the original optics too.  It's not uncommon to have wiring problems cause this, as well.

Try it with your other optics for comparison. You may have two bad optics boards.
