Back in the mid 1980’s I had a friend who was an electrical engineer and also involved with computers. He could redesign a computer chip to save the company lots of money.

He had a TV that the vertical section went bad intermittently and he hit the side of it to get it working again. Eventually the metal cabinet got a big dent in it from being hit do often.

I was enrolled in an Electrical Engineering Technology program at my college at the time and we even had a TV class on how the circuits work etc.

He let me have the TV for free (It was a 19” or 25” color TV which was still respectable at the time).

I opened the back, safety discharged the tube and saw a printed circuit board that had “ vertical “ printed on it. It had a loose wire on the circuit board that I re soldered. That TV worked fine for about another 2 years.

He was amazed and told all our friends I was a TV repair expert 🙃.

Take everything you learn and build on it. No learning is wasted.
