It is doing the same clicking as you described above.
Replaced both and it came back to life. F47 The original owner said the monitor worked for about a year, then just quit.

Yes, the CRT heater voltage comes from the flyback. I’m pretty sure they’re not made any more. Can you describe your repair at all? In my case C, a 33uf v ‘lytic shorted and took out the HOT as well. I would love to have this be a simple fix as the monitor looks in very good condition.
The original owner said the monitor worked for about a year, then just quit. Ah, it all makes sense then. Q Thanks for playing and see you real soon the next time on Vision Pro HOT where is it?? The black box in your pic is a posistor which controls the degaussing coil.
It is labeled M on the top.
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: I also found a small bulge on the flyback, as if it cooked a little bit. I have this same chassis, with 2zc4769 same symptoms. I just purchased a used pac-man over the weekend and it came with one of these monitors.
It can be had from Mouser: There is a hot piece on the board, labeled W Any help is appreciated. Anyone know where I can get a replacement for this part? No neck glow and the HV is goes up 2cs4769 about v and then cycles as do the clicks.
D Does the CRT get heater voltage from the flyback? Most 2xc4769 Q, although I don’t have a manual or chassis handy to check.

Bringing this thread back to life since I was working on the same monitor with the same issue. Attached is a picture of what I am seeing get very hot. I am thinking about replacing the flyback. It’ll probably have a smaller transistor near it That’s funny because I just installed this monitor about a year ago as well Check around the flyback for a large 3-legged transistor mounted to either a metal wall or a large heat sink.

Good luck finding a replacement flyback, though. It’s Q on thethough. I tried searching for the datasheet, but not much is coming up! The part seems to work, I now get the high pitched sound datashset you would normally hear from a functional monitor, but there is no neck glow, no picture, and i think the flyback is cooking because an odd smell is coming from the board.
