The Technical Reference for the original IBM PC has schematics - "Logic 
Diagrams" in the appendices, including the monochrome monitor. That pre-dates 
the PS2s of course but they may be similar. Usual cautions about discharging 
the anode on the CRT before you poke around in there.

I think you are right.  Thanks Tony.  It might have to remain an ornament.

IBM service manuals (certainly for PCs, PS/2s etc) did not normally contain
schematics. They were for repairs at the FRU (Field Replaceable Unit) level,
which is probably the complete monitor!.

The PS/2 hardware technical reference manual (I have it) also does not
contain any schematics. Unlike the older PC family techrefs which did
(monitors, MDA and CGA, are in volume 1 of the Options & Adapters
TechRef).

I think I have seen at least one IBM VGA monitor 'service manual'. It
told you how to get the case off, and how to adjust those presets that
sensibly could be set up in the field. In other words not much use.

There may have been a 3rd party manual, like a Sams Photofact for
it though. I don't have anything AFAIK.

Service manual for IBM PS/2 Monochrome Display?

Hi Guys,

It's a long shot but I’m searching for a manual, which hopefully someone
has scanned somewhere.

In my latest “check-my-gear-works” audit, an IBM PS/2 monitor failed. It
worked initially although brightness and contrast needed to be almost fully
up to see anything. Then the raster suddenly went. I have a power light but
no raster and no sign of life (i.e. no glow) in the elements in the neck.

The monitor is a Personal System/2 Monochrome display. Model 8503. It’s VGA
but mono.

I found one manual on the web. It’s the “IBM Personal System/2 Display
Hardware Maintenance Manual - Vol. 1” January 1993. Document Number
SA38-0053-00. Part Number 68G2616. Unfortunately (1) It doesn’t cover the
8503 model and (2) there are no pictures (I need pictures!).

Does anyone have, or knows of a link to, a service manual (PDF) for the
8503 model? This monitor is in good condition externally. It would be a
shame to throw it away but I really need to know what I’m doing before
poking around with the innards, to ascertain if it’s salvageable.!

I see someone on VCF had a whole pallet of these NIB for sale for $50 bucks
each about a year and a half ago.  220V versions even!  I haven't asked
them if there is still one available as (even if they could be bothered)
shipping to New Zealand would be an eye-watering $200 or so I imagine!
