Why would you want to change just the CRT? You may as well just buy a new TV set. Afterall you'll need to buy the CRT anyway.
Arcade and SCART have nothing to do with it, all color CRT use RGB. Taking a tube from a new arcade monitor would just be blasphemous. If you pick up a new monitor just use that because I can't imagine this TV of yours having better performance. In fact an arcade monitor probably has TWICE the performance of your TV. Just pick up all the similarly sized TVs you come across in the gutter and you'll eventually get one that will fit your TV's chassis, and you'll beautify your neighborhood while you're at it. If they are about the same size and the donor tube is in good shape it will probably work out fine after calibration.
Dude Buy another CRT TV the parts to fix your TV may cost more then Replacement TV itself it ain't worth it trust me ! I had this TV at home and the cost to fix the thing was quoted ( Parts And Labor) at almost the price i payed for the TV :L so i just got a Replacement TV instead
today looking good CRT, only few option 1. SONY KX-32HV50 2. SONY PVM or BVM Boardcast monitor 3. SONY GDM F520 or FW900
Even if you did somehow procure a replacement CRT, it's not a DIY job and you won't be able to install it yourself, let alone set it all up correctly. The other option would be to maybe ring up your nearest TV repair shop and see if they can boost or rejuvenate the CRT for you. That'll usually give you a few more years out of the old tube, but often rejuvenated CRT's deteriorate pretty quickly. Again, all that messing around will probably cost a lot more than what the TV is worth. If you can get hold of an arcade (or even a PVM/ studio) monitor, you can always cobble together some sort of SCART to RGB/HV converter (depending on how flexible the monitor is), and run your consoles through that instead. If you're extremely lucky you might even be able to gut the old TV and use its cabinet as a housing for the arcade monitor!
No. With no disrespect, give up on the idea of servicing your television yourself. If you have to ask such a question, you don't have the knowledge necessary to service a television. There are tens of kilovolts in televisions - if you don't know what you're doing, you can kill yourself. Unless the screen is smashed, it's probably not the CRT, anyway. Get a qualified service engineer to fix it if you must have it fixed. Otherwise, buy a second hand CRT television, a broadcast monitor (if you don't need the tuner) or an LCD TV.
Well i did it when i was 7 years old. Built a colour TV from a kit. But assembly from scratch is a LOT easier than replacement and the tube was factory adjusted, so there was no need for a tiresome work of adjusting coil position and convergence with magnets. But i you don't have any experience with high voltage circuits you'll better not to do it, as you need to be extra careful with anode plug because CRT tube is a large capacitor which needs to be discharged, unless your TV/monitor was powered off for more than 2 months. And it's not the only high voltage part in TV, ~400v AC with higher current can kill too, actually it's a lot higher chance to die from it. I don't know anyone killed by anode discharge but i know one guy who got hurt quite seriously indirectly, he got his hand zapped while he was adjusting a working TV and fell from a chair, hitting a metal tool chest with his head with a concussion and a crack in the skull as a result. Also CRTs are fragile and can implode and though there's a lot of stuff to prevent serious damage there's always a chance of small glass fragment hitting the eye. So it will be better to buy a new set, or find a tv repair shop and let professionals do the job. It won't cost you a lot of money. Why not GDM-C520K aka Sony Artisan ? One of the best CRT displays with no adequate LCD replacement even in $10k price range. Hard to find though, especially in good condition for less than $500-700 though. Barco Reference CRTs are good too Only one problem when using PC displays for video games and such - it's not easy to find a good composite/s-video/scart/RGB to VGA converters with upscaling. 50/60Hz <720p picture won't look that good.
