Rpi1 480 resolution and no CEC at boot

Sometimes rpi1 boots to an non fully functional state. It shows the screen at 480 resolution and CEC mode is no responding. I can connect to it via SSH and do a restart but kodi.log and dmesg logs show nothing at normal log level.

Any indication about that error?

Thank you!

osmc is fully updated, acts as a osmc mysql client of another osmc rpi3

Thanks for your understanding. We hope that we can help you get up and running again shortly.

Also make sure you are powering on your Pi AFTER your TV is both switched on and set to right input for the Pi.

Are you powering on TV (and receiver if used) before powering pi?
See: http://kodi.wiki/view/Raspberry_Pi_FAQ#TV_is_not_detected_unless_powered_on_first

Pi is always on!
I’ve enabled logging and I’ll post more info whenever happen again.

If you ever power on the Pi (including doing a reboot) without the TV (including AVR if used) being powered,
it may result in the EDID being unable to be read, resulting in incorrect resolution and no CEC until the next boot.

Ok, I followed your instructions from the wiki. When I’ve new results I’ll post them here.

After a few days, some reboots with the tv turned off, it works!
I used Raspberry Pi EDID locker
