I was unable to get a picture through my AV amp (Marantz SR7011), so connected directly to my TV (LG OLED55B7V), finally got a stable picture, applied the latest updates, shutdown and tried connecting through the amp again.
Just got a blank screen, retried a direct connection, but same result.
Tried different TV’s and my 4k Samsung monitor, all lock on to a signal, but it is just a blank screen,
It doesn’t boot fully by the looks of things so is not available on the network.
I have tried using power via the USB socket, the optical output lights up and there is activity on the ethernet port, so power looks OK, but get nothing other than the blank screen.
I’ve also tried creating recovery media and forcing it to boot from those, but no luck, just the same result.
