For the first 10 or 20 years of my repair "career", starting about age

The good thing is that everyone thinks you're a genius! I fixed my
father-in-law's TV by taking the back off and putting it back on. I
suspected a bad relay for the on-off switch, as I've seen this before,
but whatever was wrong it's been working for about five years now.
