I have Infocus 5700 and I am having problems with flickering on the screen or noise it seems like. My installer came out to trouble shoot and instead of running the video thru the HK receiver to eliminate that as the problem, he ran it directly to the projector. It seem to make things better, but it didn't fix the problem. He then suspected noise from the power lines associated with lights and ran a cable directly from the DVD to the projector and it seemed to clear up the problem, but I still see problems from both the DVD and VCR when I power them on and off, the flickering will come back, if I turn them off again and on it will stop. All of this trouble shooting leads me to believe that it is not the HK receiver, DVD, or VCR causing this problem. I thought it was the cable, but he replaced the cables with quad cables and he stated that was the best and should protect the video from noise. Is there anyone who could suggest any other ways to trouble shoot this problem, I am down to the projector or the cables??? Has anyone else seen this before???? Any help on this would be greatly appreciated!!!!!
