Orange Pi PC: Losing video signal HDMI -> TV -> HDMI

I recently bought an Orange Pi PC as a cheap alternative to RPI3B but it seems it is not as nicely supported. In particular on the same TV set (Panasonic), I am loosing video signal simply switching to TV and back (remote control TV and then HDMI again). I never experienced this with RPI2B+ or RPI3B in the past.

Is this something known ?

Symptoms disapear with: LibreELEC-H3.arm-11.0-nightly-20230114-a4874b7-orangepi-pc.img.gz (sha256)

sorry for the noise

For complete reference, I am able to loose HDMI video signal if I switch to TV for a long time ~1minute. Do you want me to watch some event over ssh to report a complete bug report ?

The system will suspend now!

Even easier to reproduce: if I turn the TV off (using the remote), I can get back to kodi.
