Yes, the CRT heater voltage comes from the flyback. The black box in your pic is a posistor which controls the degaussing coil. It’s Q on thethough.
No neck glow and the HV is goes up to about v and then cycles as do the clicks. I have this same chassis, with the same symptoms. I think I found the schematic, though its mislabeled as MTGCN alot of the parts on the board seem to match up with the schematic http: Good luck finding a replacement flyback, though. I’m pretty sure they’re not made any more.
The part seems to work, I now get the high pitched sound that you would normally hear from a functional monitor, but there is no neck glow, no picture, and i think the flyback is cooking because datasheet odd smell is coming from the board. Any help is appreciated.

It is labeled M on the top. Can you describe your repair at all? There is a hot piece on the board, labeled W It can be had from Mouser: It is 2s4c769 the same clicking as you described above. I just purchased a used pac-man over the weekend and it came with one of these monitors.
I datssheet found a small bulge on the flyback, as if it cooked a little bit. F47 The original owner said the monitor worked for about a year, then just quit.
I tried searching for the datasheet, but not much is coming up! In my case C, a 33uf v ‘lytic shorted and took out the HOT as well.
Most likely Q, although I don’t have a manual or chassis handy to check. Vision Pro HOT where is it?? Anyone know where I can get a replacement for this part? Attached is a picture of what I am seeing get very hot. Darasheet would love to have this be a simple fix as the monitor looks in very good condition. I am thinking about replacing the flyback.
Replaced both and it came back to life.
The original owner said the monitor worked for about a year, then just quit. Ah, it all makes sense then. D Does the CRT get heater voltage from the flyback? Q Thanks for playing and see you real soon the next time on Bringing this thread back to life since I was working on the same monitor with the same issue. Check around the flyback for a large 3-legged transistor mounted to either a metal wall or a large heat sink.
It’ll probably have a smaller transistor near it That’s funny because I just installed this monitor about a year ago as well
