The listed specifications are here:

You
might be able to use the component (Y/Pr/Pb) video inputs to display a U.K. 625-line picture from a suitable source, as this bypasses the NTSC/PAL encoding.
It would all depend upon whether the set will synchronize to the slightly different scanning rate. Given that the TV can also be used as a multi-scanning rate computer monitor, the chances are that it may well do so, but it can't be guaranteed.
We were just wondering if the projection screens were easier to adapt unlike regular CRT screens.
Not especially. It depends upon the circuitry which drives the display, and that can vary with CRT, LCD, and plasma TVs.
