Yup. Funny story...sort of.
I drove to Toronto and back 8hrs round trip to swap them out. I hooked up the replacement and guess what...same issue.
I had put the Integra back into the system with no issues at all with any source. When I put the Pioneer in, it was simply pull the wires from one and into the other. Everything should work, no? I knew it was wired correctly because I could see my PVR screen when the image flashed for a second every 10 seconds. So now I'm like WTF?! The Integra has worked and continued to work in the same system with the same sources and the same wires in the same configuration but the Pioneer won't work.
So I started swapping out cables. First from the receiver to the wall...no joy. The I wired the Pioneer directly to the TV and it works. So here's the part I don't understand, the wire in the wall is the same Monoprice model that came in the same shipment as the wire that works.
So what is it about the Pioneer that it won't function through my in-wall wiring (like the Integra). The receiver sits directly under the TV. No long cable run. The only significant difference (wires being the same brand/model) is the wall plates and extra cables from the receiver to the wall and wall to display (two extra 3ft HDMI). Is that really enough to fault out the Pioneer's video transmission capability?
Now I've got to call back the store in Toronto and tell them that the first unit is not really faulty, just that the receiver won't play nice in my existing system.
