This site is extremely messy, but it has many schematics of monitors.
http://www.eserviceinfo.com/The ones that I have tried are electrical diagrams of the PCB, which might take an electrician to sort out, but if someone has a model in their hands they might be able to glean something useful from it.
There was one Hitachi service manual I tried that showed the whole construction in a breakout, but no measurements or dimensions...

If someone knows a more useful site of schematics, maybe more up-to-date and organized, that'd be great.
