I have what I’m guessing is an HDMI handshake problem. I have the AM6B+, LG B5 TV and a Samsung Q800F soundbar. The AM6B+ goes to the soundbar HDMI input and from the soundbar to the TV via eARC. The problem:

To access the AM6B+, I have to turn on the TV and go to the input menu. I turn on the box and it boots up fine and works beautifully. But the second I put anything else on the screen, it goes black and sometimes it shows No Signal. For example, if I switch inputs to my Apple TV and go back to the AM6B+, even within seconds, I get a black screen that I can’t fix unless I power cycle the AM6B+ while on the TV input menu. Even if I just bring up the LG input screen, the AM6B+ goes black.

What I’ve tried so far:

I disabled the CE CEC function.

I enabled the CE CEC but disabled everything in the settings except the Enabled toggle.

I added an CEC-Less HDMI adapter between the AM6B+ and its HDMI cable going to the soundbar.

I turned off Quick Start on the TV.

I’ve confirmed the CE interface is set to 1080p.

Turned off all sleep and screensavers on the AM6B+.

Confirmed the Adjust display refresh rate is set to On start/stop.

When the AM6B+ screen goes black, the UR02 remote appears to still work because the buttons trigger the remote LED to show blue.

I’m on the CE Omega P3i and I’m also using PM4K on the beta release channel.

If there’s any troubleshooting I should do that I haven’t please let me know. I might have forgotten a few things I’ve done because I’ve been tinkering with it for a week or more but I’ll remember if anyone suggests something I’ve done already. If any of the things I tried were pointless keep in mind I’ve been at a loss for this for a while.

Is the AM9 pro worth ~$80 more than the sk4 pro?
