TVs made to soviet design famously caught fire, this was before this all printed circuit board deal was perfected. they just used cardboard-like material for that, it was flammable, absorbed water over time, and there were too closely spaced traces with high voltage on them
People just don’t remember shit that broke down quickly

TVs were hugely dangerous in the early days. People used to get electrocuted all the time. They had hugely high voltage and exploded sometimes.
fr4? that’s still the cheapest pcb material around. great for prototyping.
tvs were made before fr4 was a thing
true, but fr4 is also a nema-designation and the material existed before that.
