I tried to connect Xbox using the HDMI cable and the TV screen stays blue as if it not receiving any signal from the Xbox console. I called Mitsubishi and they said that the problem was in the CEC setting on the Xbox console and that once I switched it then the signal would be picked up by the TV and all would be fine. The obvious problem is that you can't access the settings on an Xbox console without a TV . . . Catch 22? So, what do I do to make the Xbox send a signal to the Mitsu 92"?
