Can you describe your repair at all? 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.

Yes, the CRT heater voltage comes from the flyback. I just purchased a used pac-man over the weekend and it came with one of these monitors. It is doing the same clicking as you described above.

It is labeled M on the top. Vision Pro HOT where is it??


Bringing this thread back to life since I was working on the same monitor with the same issue. Most likely Q, 2sc44769 I don’t have a manual or chassis handy to check. The original owner said the monitor worked for about a year, then just quit.

It’ll probably have a smaller transistor near it Any help is appreciated. Ah, it all makes sense then. D Does the CRT get heater voltage from the flyback? datashdet

I have this same chassis, with the same symptoms. No dafasheet glow and the HV is goes up to about v and then cycles as do the clicks. It’s Q on thethough. That’s funny because I just installed this monitor about a year ago as well There is a hot piece on the board, labeled W Q Thanks for playing and see you real soon the next time on I would love to have this be a simple fix as the monitor looks in very good condition.

Check around the flyback for a large 3-legged transistor mounted to either a metal wall or a large heat sink.

The part seems to work, I now get the high pitched sound that you would normally hear from a functional dayasheet, but there is no neck glow, no picture, and i think the datssheet is cooking because an odd smell is coming from the board. Anyone know where I can get a replacement for this part? Attached is a picture of what I am seeing get very hot.


Good luck finding a replacement flyback, though.

In my case C, a 33uf v ‘lytic shorted and took out the HOT as well. It can be had from Mouser: I am thinking about datashert the flyback. F47 The original owner said the monitor worked for about a year, then just quit.

The black box in your pic is a posistor which controls datasbeet degaussing coil. I’m pretty sure they’re not made any more.

I tried searching for the datasheet, but not much is coming up! Replaced both and it came back to life.
