Hi Ian,
You need to test your number 1, 2 and popular swithes, with the CCC Playmaker mode switch, switched off.
If the switches meter out ok pressed then you will have a fault more than likely on the CCC.
If you were in Europe you could send us your boards for testing/repair.
We normally ask for the CCC, Mechanism Control Board & Pricing Board, but in your case we would also ask for the button bank.
Regards
Alan
