Hi!
I recently picked up an AT&T PC 6300 (A.K.A. Olivetti M24) with keyboard, monochrome and color monitors.
The monochrome monitor works, the color monitor doesn't. So far I found a bad thermal fuse. Upon replacement I still don't have an image on the screen, but I do have more voltages showing up on the power supply board and hear the faint sound of something similar to High Voltage. The caps on the monitor are all within proper ESR range and I've done a quick once-over looking for other obviously/not-so-obviously bad components. I'd like to dig further but can't seem to figure out what this monitor actually is.
I've gotten as far as figuring out that it's made by Hitachi based on the FCC ID. https://fccid.io/ABL9678503CD
My ultimate goal is to find one of a few things... I really want a technical resource of some sort for this monitor, schematics or a service manual. Even a non-AT&T model number would help things, as the AT&T model number (CRT318H) isn't helping me find technical information on this monitor.
I've been Googling my heart out on this. I have gone down a few pathways to figure out what monitor I have here, but my Google-Fu is failing. I was hoping someone else here might have some knowledge they can drop to assist.
Here are two horrible-quality images I found online in case that helps anyone:
Thanks!!
