Please tell me my trusty 8700UB didn’t die. I was watching a movie, paused to do something, came back to Source: HDMI1 No Signal

Swapped out the disk player to a spare
Tried a different cable
Tried HDMI2 on the projector
Checked all connections
Switched inputs and came back to BD on receiver

Getting audio from the disk but no video
Normally I hear a lens sound switching sources and don’t now
Projector auto shuts off after sitting on no signal

Can you see the projector menu?

Unplug it for around 30 min.

So the audio is routed through the projector?

Try another display of you have to check the source is not the problem.

Or reset the projector's settings to defaults.

Where there any electrical storms in the area when the failure occurred? This is the #1 reason for HDMI chip failure, ESD (electrostatic discharge) very common during thunder storms or very low humidity. Long HDMI cables are way more likely to generate a pulse.

I never circled back but appreciate the help!
No storms, I do run a Monster power block. HDMI is 50’.

I switched to out2 (Non ARC) on the Denon receiver and everything working again. It was the AVR not the FP
