I spent some time on this board and changed most of the bridge rectifiers and all of the large caps but I have a new problem now. The old one was the 5 volts was dead, now I get all of the optic switches flashing on and off in the test mode. Of course none of optic switches work right and they just switch off and on rapidly as soon as you flip the power switch on.

All of the test voltages test OK and all of the associated LED are lit up. What did I miss?

Is there a bench test system for the WPC driver board that someone is selling? So I can test it on my bench?
Thanks very much
Russ
