I have an Xubuntu setup with Freevo running to our TV.  I had to set
the following from the command line:

xset -dpms
xset s off

where to put that really depends on your setup.  In my case, I am
using ratposion for the GUI, so I put it in /etc/ratpoisonrc.

You can try by just running the commands from the command line first
and then if they seem to help, have them run at startup.

The first one turns of dpms (energy saving features) the second turns
screensavers off.
