Think we might be both arrogant or curious instead, I also attempted a fix of my original VCRIt was a nightmare, with five heads for a perfect freeze frame, whatever I did beyond checking connections and looking for connector breaks it worked. Taking it apart and putting it back together fixed the problem. Whatever it was.
Found it funny that you wrote about this today, as I had just taken apart my car's remote starter as it wasn't working and my spouse had a meltdownLikely because he'd broken the last two, and the dealership charges $150.00 an hour to repair them. The remote still isn't working to start the car, but I've fixed it before, more of a programming issue maybe.
Good to hear more of people like us.
Curious, arrogant and just plain stubborn.

Forgot to mention. Have you ever put together a Heathkit product? I once built one of their shortwave radios from scratch as a kid. It was fun! Yoda would have probably told me that "The Geek in me is strong!"

I guess being a Baby-Boomer keeps us from adopting the notion that everything has a short shelf life and is disposable. We just weren't raised to accept such things.
