The power was turned off and on at the CU numerous times while I was
doing a job.

If off for a reasonable length of time, it shouldn't matter. It was
'cycle' I wondered about. As in switching on and off rapidly.

I've had the back off the TV, there's an IC on the power board with a

When I had a not that old TV PS fail. I bought a used board for it from
Ebay. Given that it's not easy to get schematics these days.
