I have one booth with changeovers, both Cinemeccanica Victoria 5 with 1600W xenon @55A screen is 8m wide in scope, when running without motor light is great and no flicker, when running with motor there is flicker in screen, not big, but still noticeable...was thinking on diodes, but than it would be fading in/out and not so fast, and is same on booth projectors, shutters are perfectly in sync as there is no stretching over picture or so. Rectifiers are 3phase with choke on output to reduce AC ripple, and I doubt is anything with them as they did work in one house before and it was okay, even i could check ac ripple.
So was think of shutter on V5 is maybe made with small open or something, as I head from friend he did have some problem with shutter on V5's?

When projector is not running there is no flicker, just white light on screen, when is running there is flicker, also when is running with film, but then you can see it only on white sceens. I don't think brightness is too high, as there is 55A on 8m wide screen. This machine were used allready, even don't know did this was before.....now it is, and same on both, even I don't think is soem phase or diode failure as there is same on both, and rectifiers are okay. Shutter is 2 blade type here.
