If you have the access to a line monitor put it on for a few days. See what the voltages are doing.

Also, have you tried to reflash the firmware. I have seen firmware do many strange things.

You said that you changed the power control board, do you mean the Power Supply - PU1 (p/n 4037621102 - bizhub C351/C450/C450P).
