Looking to correct the "No signal" without changing the capicitors. Does it help to run the video switching through the TV and then just run a single Optical audio into the 606? Perhaps I need to do that anyways, since the TV is newer? I'm fairly new at all this - the receiver has been running fine with cable, Blu-ray, Xbox 360 running into it via HDMI and a single output to projector, also via HDMI. I recently got the Vizio M70-D3, and I fear the 4K signal may be messing with the 606.?
I'm happy to scrap the receiver and get a modern one, unless moving all the HDMI signals to the TV might help?
