can i have an opinion on something i have checked so far to see if i am going about this the right way?
The "flickering" is evident on brighter areas of the image, such as white walls and sky, but not on the darker areas. It is a high frequency flickering, at around 30hz or so frequency i would say. not majorly noticeable, but i can see it and i am a perfectionsit.
so in my search of the problem, i have tried:
1) 10 seconds of white screen, with no film in the machine at all. flicker still present. most likely not intermittent or film path / gate.
2) swapped power supplies going to the projectors. both machines still had symptoms.
3) swapped out lamps and tried my brand new spare, same problem both machines
4) fitted new PVC arc cables (old ones insulation had broken dows and cracked), cleand all lamphouse con nectors i could find
5) have now tried "rotating" the arcs. same problem
still, pics will be uploaded tomorrow or tuesday if i can
