It's not a LibreELEC issue because the bootloader diagnostic shows "EDID=none". That is a hardware issue.
It is either:
the hdmi display.
the hdmi cable (or adaptor if using one for full size to micro-hdmi)
the hdmi socket on pi
All tests should be done with no sdcard and using bootloader diagnostic display:
Try with other socket on pi. If hdmi1 also reports EDID=none then it's not the pi socket
Try connecting to another hdmi display. If you still get EDID=none then it's not the display but the cable.
If another display works then your display is not correctly reporting an edid.
If there's another hdmi socket, then try that. Otherwise report issue to you display manufacturer.
