When i power up my Xbox my tv says hdmi signal recieved and it turns on fine but there is a completely black screen. I have an Xbpx series x and i can hear it startup through headphones and my tv works well with pther stuff such as netflix. Ive unplugged and plugged in hdmi on both xbox and tv and switched the hdmi in on my tv. I tried to reset the display settings on my xbox by holding in the disc and power button but my xbox immediatley turns off again after the second chime.
Edit: I tried my xbox on a different tv and it worked then and i can hear my xbox through the original tv so its connected via hdmi so idk what the problem is with my tv.
