Quoted from Cycloneman:

The clock second hand is probably not going thru/breaking the optos,Try adding some electric tape around the small piece of plastic that goes thru the opto

If you replaced the boards, and the opto's are "acting" intermittent, then look at the hour and minute hands. The poor tolerance in the shaft, along with the plastic hands bending outward from the heat causes the plastic tab at the back of the hands to not pass through the optos. Once a hand misses one opto, the clock is marked broken....

You need to make sure the optos are being broken by the minute hand, and that when you put the clock back together it's not 30 minutes out of sync....

These are most likely your issues. Prove it by taking a credit card and breaking each opto by hand in clock test, if the break is rock solid with the credit card in the opto, then you know it's the hands. Use the test to move the clock slow and get the minute hand to each quarter hour, when it's in the opto, stop the motor, and wiggle the hand, I bet you find there's enough play that the opto flutters...
