Did you ever find a matching schematic? Sony F520 (chassis CR1) maybe?

Unfortunately not.
I'v got the service manual for the SONY GDM-C520K. It's similar to this monitor in some ways, but it's not the same.

I currently have the monitor setup with my G3 Beige, as it's running OS9.2:

The Apple USB Display Service Utility only runs in OS9, and I now have it installed, allowing me to make fine adjustments to the screen when I get around to giving it a full tuneup in the future:

After running the monitor for quite a while, I have noticed that it will indeed need a Flyback transformer replacement, as every few hours I’m getting the notorious “click, pop, Zoom”, which is the symptom of a failing Flyback transformer!
Thank God I managed to get a new one!
This repair will have to wait until I have the correct tools to do the job myself.
I can live with it for now, knowing that I have the spare Flyback!
I will do an update on this in the future.
