I was at my parent’s for the weekend and I used the time to setup OSMC on my new RPi 4.
They have an older (~10 years) Samsung TV and everything worked fine (including CEC or whatever it’s called on Samsung).
I came home today and excitedly tried to connect the RPi to my LG TV (bought it almost 2 years ago) and i was disappointed seeing No Signal on it. I tried all the ports combinations (both tv and RPi).
I also have some very very cheap generic TV (~5 years old) and on it everything works fine too! Same device, same cable, etc.
I also have an older RPi 3 with the latest OSMC on it. Tried it on the LG TV and everything works fine. The only difference is the cable. On the RPi 3, I have a regular HDMI cable, not the smaller one as it is on RPi 4.
Next, I did a backup of my SD card and tried putting a fresh copy of OSMC on it, but with no luck. Still “No signal”.
I moved the device to the older tv and (as everything works there) i finished the installation and connected the device to the wifi.
Then i connected it to the LG TV again. Still nothing.
Here’s my log after I connected it to the LG: https://paste.osmc.tv/uvefojineg
I tried many things i could find here, on Reddit and where not, but couldn’t achieve anything.
