black screen when connected to TV via HDMI

daviddoji · February 12, 2021 at 8:22 PM

I freshly installed the last version (LibreELEC (official): 9.2.6 (RPi2.arm)) using

LibreELEC.USB-SD.Creator.Linux-64bit.bin under Linux and set it up using an HDMI cable in a pc monitor. Everything works out-of-the-box. I even mounted my nfs shares and all looked fine. I switched it off and plug it in my TV.

When I turned the rpi on, I got a black screen. I tried two different HDMI cables and two different HDMI inputs on the TV with the same result, a black screen.

The rpi is reachable through ssh, so please ask for logs if needed. Here it is the dmesg:

Any help would be appreciated.

On the other hand, connected to the pc monitor, output is OK, those are the values:

raspikodi:/ # tvservice -s
