I dont think so. I think the last plant that was open was in Singapore and they closed their doors a couple years back.
the last CRT rebuilder here in the country was Hawkeye and they closed their doors several years ago.
so once the CRT is gone, it's gone... no coming back for it.
this is a huge problem we are encountering in the vintage TV restoration world. if the CRT is a dud or has weak emissions you can't replace unless you find a used one somewhere which is getting worse and worse each day.
these computer monitors aren't quite old enough to have this problem but another 10 to 15 years in the future it's going to start happening. especially if they are still used a lot today as a tinkering machine.
they will start getting weak in emissions and on a color CRT you can tell this by looking at the colors if they are bleeding like sideways fire.
usually the first thing that happens though, is you start to lose focus on the corners, that cant be adjusted. and then the color starts to bleed like fire. when it happens to this point that means the CRT electron gun is weak in emissions and that the CRT has to be replaced.
