Oh sorry, The TV is working fine. The screen I'm referring to above is the 1070 screen, not the TV.
The TV works unless I run the signal through the 1070. In other words, it's not just that the screen on the 1070 isn't displaying. The audio and video isn't working as well.

When I say I turned on my TV, I should have said turned on my HT.

The problem is that the 1070 screen is blank. It is unresponsive to the buttons or to changing inputs. The standby light changes from orange to green, but thats it.
