Wonder what the mean time between failure is. I see one out in there. I think it quite hard on an old crt TV to keep a full bright screen lit. This will put the maximum load on the CRT driver. Some cheaper TV pictures would increase in size slightly with a bright screen. This is an indication of the accelerating voltage sagging with the load. The slower electrons being deflected more by the scan coils. Always have a soft spot for CRTs, I been working on CRT equipment of one kind or another since the late 60s.

Interesting. Using lighting (of sorts) as art reminds me of the gallery of SOX lamps in London a few years ago. What was really annoying about that one was we were actually in London at the time it was on, but didn't know anything about it

You see that in anything other than a planned art exhibit and you'd take off running! Imagine seeing this scene in an abandoned building
It looks rather other-worldly as it is. It's quite a good effect.

That was certainly an interesting idea from the artist(s). I've never seen anything quite like this again.

Ria - I can imagine how you felt missing out on this exhibit given how much you like SOX lighting.

Tuopeek - Good point about the way those TVs are used, that cannot be good for their electronics. And good catch about that dead one at the back, that's an interesting detail that I did not notice back then.

@Tuopeek - Yeah, CRTs are good. Some game enthusiasts (I refuse to acknowledge 'gamer' as a word) swear by them. We recently saw a video on YouTube (see here) about the largest one ever made, 43 or 45 inches I believe, by Sony. The guy who made it managed to track one down in Japan and got it shipped to him in the US. It still just about worked, but did need a lot of work to get it in full working order.

@Max - Indeed, it was really annoying, not a lot we can do about it, though

There is a big CRT monitor following but funnily, I think it is because CRTs with their raster scanning soften the image of old games machines which look quite blocky on an LCD. A situation where high resolution is bad. I think National Air Traffic Services may have also used these large SONY CRTs. In the 1990s air traffic control used massive SONY monitors for radar displays that required to be moved by powered trolleys for maintenance. They were phases out for Barco LCD monitors and the Scottish control centre never used them so I didn't get to see them other than in pictures.
