16.001 My display is sharp but it seems to be unstable. Is there a quick, easy fix for this?
Monitor RepairMini-Manual (Q&A 001-014) 4/98 version
This mini-manual describes Repairs & Adjustments which usually involve
removing the case. Before removing the case, check to see that the your
problems are not due to a poorly connected monitor cable or misadjusted monitor
controls.

Maybe. First, check your cable connections to make sure they are solid.
Also, try diddling the side and back controls. Sometimes, these become dirty or
develop bad spots.
If diddling a control seems to cure or nearly cure an unstable, jumping,
etc. display, you can be fairly sure that a squirt of Control Cleaner will
help. The cleaner needs to reach the control's resistance element-- the place
where the wiper touches the carbon track in a potentiometer-- and you should
turn the control back and forth after squirting the cleaner. Probably, you will
need to remove the case to get a good shot at the dirty control.
