We have had to replace the screens on our mid nineties vintage, HAAS VF-2 and VF-3. We did notice on the new screens an "extra" plug.
Nice having a screen you can see, HOWEVER, now when the spindle rotates
you get squiggles and such across the screen(s). (kind of like a TV screen with static if it's in the same room as a microwave when it's running)
These are the monochrome screens.
How can we(I) isolate the screen from the feedback? To eliminate this
problem.
Any insights would be appreciated.
