Having a problem with the monitor on a 2000 VF3.

[Eric MFG]

After the machine is powered on for about three hours the graphics shift to one side and then the monitor goes blank. My thoughts are there is a bad compacitor somewhere if so where? Has anyone else experienced this problem. Also we have a 1994 VF3 with blown transmission would the video related parts fit in the 2000?

Thanks Eric!

Is the machine still fully functional just no screen? I take it you have the CRT style monitor?

[Eric MFG]

Yes it's the amber text CRT style. The machine runs fine and will run programs no problem.

It sounds like the monitor itself. Diagnosing it can be dangerous if you don't know what your doing. High voltage. The monitor itself uses a MDA signal. You say you have another machine that you can use parts from. That monitor will be a drop in replacement. It is very straight forward. Haas also sells new monitors as well but they are not cheap.

If both machines have the CRT monitor then they can be swapped with each other.

Hey Guys,

Thanks for the tips! The monitor transplant was a success and the machine purrs like a kitten. Would anyone have a schematic for the monitor PSU? Otherwise my plan is to reverse engineer as much as I can and replace all the electrolytic compacitors.

Thanks,
Eric

If your good with electronics you can troubleshoot it like a standard computer monitor. Replacing electrolytics isn't a bad idea as they dry up over time. It might be something else however. Sounds heat related to me. Maybe get it to act up again and try some cold spray to help isolate the problem area. Check solder joints as well. Here is a good link on repairing these types of things...
