RE: I said I wouldn't...

Andy,

You've no chance mate!

The LCD in an LCD projection system is a totally different beast to that
in an LCD screen. I've seen allsorts of guff in my time like ideas to
make a CRT into a projector, image enhancers and magnifiers but I have
never even heard of anyone attempting something like this simply because
it is not a viable proposition.

IMO, the picture if you could see it, would be so washed out it would be
un-watchable and that's if you could sort out the physical problems with
the original LCD screen.

The best advise I can give you is to start saving!

K.
