I have a Sony NSZ- GT1 Google TV hooked up via HDMI to a Motorola dcx3400 cable box and a Onkyo HT-R380 5.1 A/V receiver. When hooked up HDMI from cable box to NSZGT1 to receiver to TV my picture changes from a green screen to hash (no signal) to picture without sound. This cycle just continues. All works fine if a bypass the Onkyo receiver. Any ideas? Sony claims that the cable company is the issue, but as I said it works fine through the cable box when I bypass the audio receiver.
