I'm experiencing intermittent video dropout problems to my projector, which seem to occur when some other items in the house kick in - e.g. I noticed it coincide once at the exact second that the fridge compressor kicked in, and I can also simulate it when turning on a lamp with an energy-saving bulb.
The reason I think this might cure the problem, is that if I connect my blu-ray player direct to the projector, and turn the lamp on/off repeatedly, the picture doesn't drop at all. But connect the receiver to the projector, and turn the lamp on/off, the picture drops more often than not when the lamp is turned on, and then re-appears a second or so later.
This makes me think that the blu-ray is outputting a stronger voltage (or maybe current?) than the receiver, and the signal is not affected by other appliances turning on. I'm using good quality cables from Rapalloav between the source and the display (at either end of an HDMI/Cat5 wall plate), and the fact that it works okay when the blu-ray is connected direct eliminates the cables as being the problem point.
I've tried a regular HDMI signal booster and that didn't make the slightest bit of difference.
Anyone got any thoughts / comments or other suggestions?
