Unfortunately I was in the same boat as you and I had to resort to hooking
up my TV to a Windows computer and run PowerStrip over a DVI connection to
the TV. I you have a windows computer to do this it is fairly simple and
only takes about 15 minutes. I checked the Modeline Database and nothing
comes close to your TV
http://www.mythtv.org/wiki/index.php/Modeline_Database
So you have to either use Powerstrip or you can check out your X11 logs and
post them here. I don't know what flavor of linux you are running but mine
are at
/var/log/Xorg.0.log
Sorry I wasn't more helpful but if you need more help from either route post
away and we can go from there.
