Vision Pro HOT where is it?? No neck glow and the HV is goes up to about v and then cycles as do the clicks. Any help is appreciated.


Most likely Q, although I don’t have a manual or chassis handy to check. It’s Q on thethough.

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 Q Thanks for playing and see you real soon the next time on 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. There is a hot piece on the board, labeled W The original owner said the monitor worked for about a year, then just quit. Can you describe your repair at all? Attached is a picture of what I am daasheet get very hot. It is labeled M on the top. I would love to have this be a simple fix as the monitor looks in very good condition.

The black box in your pic is a posistor which controls the degaussing coil. In my case C, a 33uf v ‘lytic shorted and took out the HOT as well. Replaced both and it came back to life.

I have this same chassis, with the same symptoms. Anyone know where I can get a replacement for this part? I tried searching for the datasheet, but not much is coming up! F47 The original owner said the monitor worked for about a year, then just quit. That’s funny because I just installed this monitor about a year ago as well 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: It can be had from Mouser: 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 an odd smell is coming from the board.


D Does the CRT get heater voltage from the flyback? I am thinking about replacing the flyback. Yes, the CRT heater voltage comes from the flyback. Good luck finding a replacement flyback, though.

I’m pretty sure they’re not made any more.

Ah, it all makes sense then. I also found a small bulge on the flyback, as if it cooked a 2sc4679 bit. Bringing this thread back to life since I was working on the same monitor with the same issue.
