I think if you turn it on and then hold down the power button (for 5 seconds), it'll beep a few times and "reset" itself back to defaults.
Worth a shot to see if you can get the video back.
I've had that happen with mine, for the opposite way (I have HDMI for video, but not audio) and it'll come up asking me if I want to output everything with HDMI. If I choose "Yes" then I get no sound and have to reset the audio. (of course if I say "no" then I don't get any video). My guess is my wife holds down the power button and resets the stupid thing, so when I power it back up it recognizes that an HDMI cable is plugged in and assume I want to output everything with HDMI.
So that's probably what happened....except your wife probably said "yes" and now it's outputting video through the HDMI (and thus you can't see it). Reset it again.
A minor annoyance, but having to hold down Power for 2 seconds to turn it off, yet 5 seconds resets the whole thing is pretty stupid. Shouldn't be a problem for most people...but my wife is not "most people"
