Hello ... I am based in Bristol, UK, and I recently tried to run my Indigo2 and GDM-20D11 SG monitor after apx 12 years in a box. At first I got a small region of the screen lit up, which tried to 'correct' itself, but after a couple of reboots the monitor is showing no sign of life at all (nothing glowing inside the casing). The power swich lights are ON, but otherwise seemingly dead. The power cable plug had a 5 amp fuse inside. Could I have blown the monitor? (I have seen references to 1.5amp fuses re the monitor!?) - does it contain any internal fuses? - Does anyone have any other suggestions I could try? Maybe the video cable could be the problem, if it had been bent too much? - but I guess the monitor would still show signs of life? Everything worked perfectly before I moved and boxed it all up!! - Thankyou, if you can help!?

If the fuse blew then I would be suspicious about what caused it. You might try the SGUG Discord chat (from our main website), I know we have some people there that have done CRT repair before. It will likely be a more in depth troubleshooting process with the case open.

@Elf I think the best advice we can give since monitors can be fatally dangerous for inexperienced people to work on, is to recommend the OP to take it to an experienced CRT service person in his area. No offense to the OP but I get the impression he is not electronically/technically experienced in this area.

Hi from Somerset, can’t help unfortunately but suggest you look up retro arcade repair specialists as they still often deal with crt displays, if they can’t help they may be able to recommend somebody who can.

Hope you can get it fixed!

I agree that CRTs can be dangerous to work on, which is worth mentioning, and rightfully so often the first thing that gets mentioned. My own personal view is usually to let people decide what level of risk they feel comfortable with, but it is definitely not a good entry point into electronics or repair.
