You could probably use xrandr or xset from Ctrl-Alt-F1 to unblank it.
Something like:

xrandr -d :0 --output DFP-0 --auto

or

xset -display :0 dpms on

I am guessing this is why I have these in my /etc/X11/xorg.conf:

Section "Monitor"
        Identifier "Sony TV"
        Option "DPMS"   "true"
EndSection

Section "ServerFlags"
        Option "BlankTime"              "0"
        Option "StandbyTime"    "0"
        Option "SuspendTime"    "0"
        Option "OffTime"                "0"
EndSection

I have had them there for many years, but recently I was scratching my
head wondering why.  I can see why I had the times set to 0, but just
why I still had DPMS enabled was bothering me.
