No intent on skimping details. When I was posting the previous response it notified me the name of the vendor was a banned word in the forum for some reason. I was in a hurry and omitted that portion instead of editing or obfuscating.

There are issues with projectors if they are overheating, then they shut down after such kind of period. It looks to me that this happens on your setup. Maybe an firmware issue of the projector or AVR with a specific frame rate or possibly a real hardware issue. Do you have an OSD with information about current input signal on your projector to compare the incoming signal with the working ones of Roku/NUC
Which projector and AVR do you use?
Not an overheating thing. Again, can run it for hours with other devices attached and it plays fine. Ex. Just ran a NUC yesterday for around 11 hours without issue.
I'm going to dig more into the signal/frame rate/etc side of things.

Right. One of the first reasons I disabled CEC is because the power-off timing WAS consistent. I probably should get a timer out next time to gather the empirical data.
Highly improbable that it's a hardware fault with the projector. No comparable behavior with other devices attached (Roku, NUC).
I may swap out all the cables as well to verify signaling.

No. The projector just turns off. Shuts down exactly as if I were to hit the standby/power button on the projector's remote. I need to hit the power button on the remote to turn the projector back on to re-display the picture. The Pi 5 and receiver continue playback through the process. However, I do notice a brief blip in the audio when this happens.
Resolution is 1080p with 60hz refresh.
I will need to test with a different screen and for straight-to-projector. I have verified the behavior is not occurring with a Roku device or Kodi (Windows) on a NUC plugged into the same AVR (port).

Bit of an odd issue I'm looking to troubleshoot and looking for suggestions on where to start. I have LibreElec 12.0.1 installed on a Raspberry Pi 5. It's a new deployment/set-up. Through testing over a few weeks I am getting a behavior where my projector is shutting off at a consistent interval during video playback. I need to check exacts again but it's in the 25-30 minute timeframe. Example: 25ish minutes into a longer movie, projector will shut off but my receiver and Pi 5 will continue to play. The playback may stutter a second or two after this happens as well but resumes. There are occasions, maybe once every 5 or 6 times I try, where this does not occur. But it is consistently happening every time outside of that.
At first I thought it may be an issue with CEC and my receiver and projector. However, I have disabled CEC (peripherals) from the input settings in Kodi. CEC is NOT a requirement for my set-up. The behavior persists even after disabling CEC.
I have ruled out the projector itself. The behavior does NOT occur with a Roku I have attached to it nor does it with a Windows-based system running Kodi (Intel NUC).
Let me know if anyone has any suggestions on where to begin or what to do next.
