Thanks for your quick response.
I have fixed it. The resolution set itself to 2160 which made the TV seize up.
I managed to access the receiver via OpenWebIf from a nearby laptop and made it show UI screenshots that updated every second. That way I could navigate to
Main Menu/Setup/Audio & Video/Settings Mode and set this to 1080i, then Save that setting with the green button. Now I'm back in business.
