This is inceredibly annnoying. Every time i change a channel in DirecTV the screen goes blank and the volume goes out but comes back on but the TV stays blank. I have the DirecTV and BluRay running through the VSX then out to a Sharp Aquos 70" 3D. All of the sudden this started happenning. If I undo the HDMI going into the TV and re-plug it, a little box comes up on the top right of the TV and the screen turns back on after about 10 seconds. when I watch something on the DVR it transfers over fine. I tried replacing the HDMI cables, twice. What's even weirder is went away for a week and came back and for 2 days everything worked fine. I think it's a setting with the Receiver, but it might be something with the DirecTV receiver or even the TV. Any suggestions before I call a A/V guy and waste $100????? Thanks.
