OEM Power Supply Answered

I have an unregulated power supply, with a bridge rectifier. I suspect that the rectifier is damaged. I measured the components and the voltage on the rectifier, every connection past that measures 0 volts. Shall I replace the 4 diodes?

I am assuming you measured the voltage immediately before the bridge? If that is at the proper voltage/amperage, then yeah, the bridge is probably at fault. But if there isn't anything coming out of the secondary of the transformer, you have a bad one of those.
