I take in what I can albeit space is limited. They are worth a lot to me - not in a monetary sense of course.
All screens are "screened"(brightness/color/sharpness) and then rated in a tier system which means that burnt out ones get used first and then discarded - given the phosphor or the electron gun(s) is/are dying. Even putting these ones away hurts a bit as sometimes it's a tasty model, for example, a 22" Iiyama or similar.
Worthier ones are being stored for "service" and some gusto-usage.
Where are you situated - Europe or US? I heard that in some parts of the west Crts are getting scarce... it may be useful to connect the CRT collector's hobby with an official outlet. Something like cooperating with a department for technology or art - this way funds could be raised to keep the screens working.
I'm from Germany. Here I still see CRTs being offered from time to time, but mostly they are too far away to pick them up. But from my observations over the last 3-4 years they are getting rarer. And yet there doesn't seem to be much interest in them because if an ad shows up it doesn't disappear very quickly. (Right now I see a 17" and a 15" being offered since 2 months)
I know that not only Retro-PC-user look for them but also collectors of arcade machines.
I'm not an expert on CRT technology, but what I know is that Sony-tubes become brighter just by sitting unused for years. But that can be fixed by software. The same might apply to the Mitsubishi Diamontron (Iiyama). So maybe you shouldn't throw away the 22" too early. I have one such a problem with a Dell (with Sony tube inside) that I plan to try to repair 'some day'..
Germany is one of the better countries for retro things - big(ger) nation were some people are neat and keep things tidy. I'm in Austria, which is similar but the "market" is way smaller and often less interesting. Yes, Crts still do not get too much love... fortunately or one would have to pay a Lot (more) for them
The IIyama was shot as one of the emitters seemed failing - the picture always had a red tint which did not stem from a bad solder joint. I encountered "brightening" of Sony tubes in an IBM P260 - with the right tools it's just a small service routine. Nonetheless a pesky issue.
Hello, I looked everywhere for your reply, I read it and then totally forgot in which thread it was in!
I even created a new thread to try and obtain the answer, here: Sony CRT TVs and Monitors "breathing" and brightness problem - which caps/parts to replace to fix it?
But I can just delete it and ask here: could you please elaborate on the procedure to solve the "breathing" and brightness issue on Sony CRTs? I have that same problem with a small 1999 Black Trinitron, I adjusted the brightness to mitigate the issue of distorted geometry and it worked, but I assume it will only get worse with age, and that servicing it is inevitable. How did you proceed to do the service? What parts/capacitors did you replace, if that's the case, and if it's the same between Trinitron Monitors and TVs? Many thanks for your help, glad I could finally find your reply!
