When a power failure happen in a module, First watch the indication in the module like trip indications due to overload,earth fault etc. The indication shows the reason of the power failure, we can check through it. if there is no indication means total supply failure.

Check the fuse if it is there. Check any burned component or any carbon deposited component. Then take an ohm meter and see if any opened component is there.
