No, the HDMI cable and TV inputs are not the issue, I tested 2 other devices using the same cable and hdmi input and had no issues
The closest I got to making it work was resetting the V6 box, I THOUGHT this worked because the “welcome” message in several languages was shown on my TV, followed by “starting up” for a couple of minutes. Then ... Nothing, no input detected even though the box indicates a white light signal. I don’t understand why the welcome and loading screen worked, and my other devices worked, but this just stops once it’s turned on.

I tried disconnecting the hdmi multiple times at both ends and I tried using a different hdmi port on my tv multiple times. Also tried restarting the box and the tv multiple times, does not work
edit: I changed the hdmi input type on my tv from 2.0 to 1.4 and that fixed it
