As bad as it is to reply to one's own emails, I've done some testing and found: - The AC inlet fuse (2.5A 20mm ceramic cartridge fuse) is blown. And by blown I mean completely open - infinite ohms. I can't use the "is the fuse melted (soft blow) or metal coated inside (severe overload)" trick because it's a ceramic-body fuse...
- All the rectifier diodes in the PSU section appear to be functional -
0.5V forward drop, "infinite" reverse drop, according to my DMM.
- The thing is absolutely full of "Luxon" electrolytic capacitors. Best guess about 20 of them. That and the fact this thing has an mfg date of 2001 puts it square in the "counterfeit capacitors" time frame and makes me bloody suspicious. No signs of cap leakage or bulging caps, but I'm still suspicious.
- The case is really easy to open up. No latches or hidden screws at all. Put the CRT face down on a towel (unless you WANT to scratch the CRT that is), remove all the screws on the back (4 around the front edge + 3 on the back panel) and lift the back away from the front section, shaking it gently if it gets stuck. Reassembly is just as easy - put the cover back on, then refit the screws.
- All the PCBs are marked with a logo that looks like "JEAN" - i.e. these guys: . So 99.9% chance it's a Viewsonic rebrand of a JEAN monitor. Why am I not surprised? Service info appears to be available, but only to those with a username and password, and no hint on how to apply for access. Yay.
I've found a few of the part numbers too: Monitor P/N: VCDTS22475-1E CRT: Chunghwa M41AJR53X76 / CP5440BNAC1S-TC / No. B 1163581016 Mainboard: G73FM 2202116700 VER:1.06 2001.04.20 Audio riser card: 2202117200 Barcode sticker on mainboard: 7562-00191-01050-0.0-A15025
