I’m running OSMC on Raspberry Pi 3. RPi is connected to an AV receiver, which in turn is connected to a video projector. The setup has worked flawlessly for a couple of years, but now I have a strange problem.
An example: I watch today something with OSMC, leave RPi on but power off both the receiver and projector. Tomorrow I turn on receiver and projector, but the screen will stay blue (i.e. no signal). Sometimes OSMC screen will suddenly come up in a couple of minutes, sometimes I will see just “white noise”, sometimes the screen stays blue no matter how long I wait.
If I log onto OSMC console and do sudo shutdown -r now, I will see the OSMC logo before the screen goes blue again. Again, after the reboot, the OSMC may work after a while.
Also, if I switch off power plug from OSMC, the screen will be blue after showing OSMC load logo, but typically OSMC will be work in a minute or so.
Once the OSMC GUI is displayed, it works flawlessly.
