For about a week my Xbox no longer turns on my TV when saying "Xbox On" or even turning on the Xbox manually. The receiver turns on, the Xbox turns on, but not the actual TV. The TV will turn off when I say "Xbox Turn Off" so it's very strange. I've reset the TV settings and the "Mute" test it sends works perfect.
I recently cancelled my cable and removed the box around the same time as the 2/15 update so I'm not sure which actually caused the problems.
Any thoughts? I need to figure this out so my wife gets off my case. :)
