I had that same problem a couple of years ago. IIRC, when you turn off
the TV, X decides to switch to another video port and turning on the TV
doesn't switch back to the HDMI port. I'm pretty sure that adding the
ConnectedMonitor and UseDisplayDevice options to the Device section of
your xorg.conf file will fix this. I've attached my working xorg.conf
file as a reference.
