What does your Xorg.conf look like? It sounds to me like your LCD TV
only accepts certain resolutions, and although you have set it correctly
within Gnome (or whatever window manager you use), the main Xorg.conf
file has a different default resolution, which is causing you problems.

If you know for sure what resolution it should be, I'd recommend
dropping into recovery mode (or simply stopping X and dropping into a
terminal), and then running sudo dpkg-reconfigure xserver-xorg - this
will walk you through setting up your Xorg.conf file correctly.
Alternatively you could edit it yourself (having made a backup of
course).

Cheers, Tom
