I've had this problem with every receiver I've bought in the last 3 years. I've also sent them back for repair, only to have it happen again. I will use it for a few weeks with no problems. I get home from work and turn it on. It starts up, defaults to TV, then Linear PCM scrolls across the screen. There is no video or audio. Until tonight, resetting the receiver by turning off and holding down the power button solved the issue. When I tried to turn it on it showed linear pcm. I reset it. When it came back on it said linear pcm. There was audio, but no picture. I reset it again. It went back to linear pcm. I turned it off and let it sit for 10 minutes. Turned it back on and it worked. The first time this happened I was told to buy different HDMI cables. I replaced all of them with 4k compatable ones. That didn't make any difference.
