They will not come back for classic gaming trust me. They will come back because they were a better made tv all around.
We will eventually get back to quality and repairing things as opposed to being a throw away society happy to replace the junk forced on us that we buy every 3-5 years.
It's cyclical . Electron tubes still are going strong, though there are no USA mfg.s that I am aware of. The same will be true for analog over digital, which has already made a big comeback in the musical instrument sector.
I have yet to see a flat screen that I like over any CRT I have owned or currently own.
I'll keep buying CRT's till I can no longer do so, which unfortunately will be soon as both of the brands that I like, Panasonic no longer carries its own parts, Sony the same from what I gather.
So repairing them, unless you are a TV repairman with oodles of new old stock parts on hand, will become a thing of the past in the next few years.
Sony auth repair will not even look at your CRT anymore.
