I think that is beyond my capability.
Sounds like it's Time to do some checking before next power on. Maybe using a series test lamp jig or variac would be good to avoid further damage. Semiconductors are gonna be quicker at blowing than you getting to a switch.
A series test lamp jig takes about 10 minutes to make and costs about $5. A variac may be out of your price comfort zone though.
Google is your friend if you need details of how to make a test jig. Z
