I still remember support for life.

TV, refrigerator, recorder, whatever electronics, broke down and I or my parents would take it to one of several repair locations around town.

Software coming in eproms or disks meant QA was actually a thing to get right, not as online updates that eventually stop.

I think that's kinda different - these repair shops could repair anything because things were repairable and because people had the skill to do so, and because the financial reality meant that repairing something almost always made more sense than buying new. I still know these people who are happy to do soldering on modern TV motherboards to fix them, but it's just very hard to justify financially in Western economies. I once shipped an entire HiFi system to a repair shop in Poland because a guy there could fix it for equivalent of €50, even with shipping the thing there and back it was worth it. Meanwhile my local repair shop wanted €100 just to diagnose the issue.

How well do those TVs pick up HD digital TV signals?

You can get HDMI to analog converters for pretty cheap for use with streaming devices. You can also get devices that will receive digital OTA signals directly and output them to analog signals.
