I had been working for a garage door installation place. And have had to replace the main board in the operator A LOT of times because of lightning damage. But being old school I was curious about what common components get wrecked because of the lightning strike. Currently I have a powered speaker system, 2 speakers and a sub. and after a storm the sub no longer works but the two speakers work fine. I am somewhat electronically inclined and I'm curious what is the most common component is that gets blown up
Typically the power supply. Sometimes as simple as a blown fuse, other times it can wreck the transformer, bridge, regulation circuits and of course resistors etc. Check fuses first.
