My Emerson LC320EM8A blows fuse as soon as surge protector turns on.
Isolated main board and still blows. A visual of board couldn't find anything. Where do I look next? Bad doide on bridge rect or zener diode.
Just which one to start with and can I test on board?
Thanks,
Mitch

Just one of many possible: Dead set no lights, D633 on center module shorted.

You could consult with a psychic Smile or you could grab a DVM and check the semiconductors on the main board. If checks bad in circuit, float one end and test again.
