Right you are; this one's a PVM-8043MD. Looks like it lacks the 16:9 mode, manual degauss and tally light. I believe MD signifies "medical"; removed the cover and there is some shielding around the deflection yoke.
Thank you for mentioning that model number. That page has some good troubleshooting info relevant to the white balance problem I'm seeing with this one. Will post something nice if I can fix it!
Pretty sure it's a closed loop surveillance CRT TV used in security rooms of yesteryear. You can even see a small handle at the front meant to fit inside a rack for an array of them.
Very nice! My brother pulled something similar out of some old news van in a junkyard. He was there looking for taillights and came across it and pooped his pants
The monitor had two obvious problems at first: yellow tint and rainbow patterning. Quick pass with a degaussing coil took care of the latter. Hooked up a composite lead and threw on my low-quality DVD-R copy of my VHS copy of my NTSC Reference Laserdisc and made some quick adjustments to the monitor; results below:
monoscope
SMPTE bars

The colors in the game look different in these pictures; hard to make them accurate. But it looks good in person. (edit: better camera settings, more colorful game)
Was reaching for my blue filter to set Color/Tint when I remembered this monitor has a "Blue Only" feature; pretty neat! Surprisingly, adjusting the Screen control on the flyback transformer seems to have more effect on the white balance than on the contrast. Still, had to maximize the Blue Gain control on the PCB and on the front panel to get the white balance close as possible for the time being. Heck, I might not actually bother with it much further; it looks pretty good. Will have to try the RGB inputs.
Dude. You ripped him off!!! The price tag clearly says double what you paid! You're basically stealing from this shop owner. Pawn shop profit margins are razor thin!
