Don’t you still see this when using an OTA ATSC tuner on a newer LCD display? I thought this was a function of the signal generation and not the display technologies.
Cheap led tvs were like 1/5 the cost of Analog TVs. The digital switch over really finished them off too.
Really it’s the size/price that did it though. My buddy paid I think $3k for a maybe 40” Trinitron in 99-2000. It probably weighed 200lbs. Looked amazing at the time but it was probably only months before big leds came out. Plasma might have been a thing then but we’re like $10k+
I think they're more likely to have been scrapped than other old tech.
They're bulky, and mine was too heavy to get out in the attic. I still have my ZX Spectrum and Amiga, but the CRT needed for lightgun games is long gone.
