Re: Commodore 1084-D2 Monitor Repair
Another left field suggestion - whatever it is is:-
-Periodic, but not synced to any other frequency in the monitor
-Of very short duration
-Powerful enough to disrupt the operation of indirectly related signal paths
Could this be something arcing - fault within the LOPT perhaps, or insulation breaking down across some other component or PCB path? Try getting the unit into a place of complete darkness, let your eyes adjust and see if you can actually see anything flashing over.
