We have an entry level receiver: Sony STR-DH720, and an Optoma projector (i don't have model number handy but can chase down if necessary).
A few weeks ago we started to see a recurring issue where the image displayed on the screen would start getting distorted like all the red was missing or it would have a "saturated look" to it. We had a "protect" warning occur a couple of times too. I unhooked a couple of the speakers when that happened, cooled the receiver down and we haven't seen that since.. but the image "flip out" still occurs on DVD, Satellite TV and Xbox. The "cure" is what has me confused.. we turn the projector off.. wait a few moments and then turn the projector back on and the image is fine again.
I have suspected this is a receiver problem, and not the projector, but why would shutting the HDMI-connected projector off and restarting it fix the issue (temporarily)?
Something possibly related: We have long struggled with our setup for a variety of a reasons- but almost always it's surrounding HDMI connections either not carrying sound, not giving us the correct resolution, latency and "flippiing" between analog and digital audio. But we had a few months of stability before this lastest round of issues.
Also possibly related: a cable installer working on replacing the cable box upstairs (not part of this theatre setup) said something to my wife to the effect that he suspected (my term) "stray voltage" and possible improper grounding. Not sure if this was due to an appliance? or that outlet? or the house in general??
Thanks in advance for any consideration
