I saw alot of these banners about turning a 19" tv into a 100" projection TV this can not be done at least I don't think so if any of you have seen or talked to any one that has seen this please let me know. how it can work.

Elf, as far as I know, this "trick" involves using a large lens to project a TV's image at a screen.

I can't imagine that the picture is very bright, as the amount of light that is emitted by a 19" TV would have to be spread out to a 100" size.

They usually forget to mention that you have to go inside the TV and re-wire the coils on the neck of the CRT to reverse the horizontal scanning direction.

Yes the trick does work.. Does it work well? Of course
it does not..

Basicly for your 10 or 12 dollars you get a Freshnell
(Sp?) Lens and plans to build some ugly looking wooden
frame to set your TV into (upside down) and it also
holds the lens..

This type of thing might be okay for parties but not
for critical movie watching where quality is a concern.

Larry,

They mount the TV upside down I beleive.. Do the chokes
still have to be reversed?

I thought so i could not see a possible way to do this and keep the picture good unless you had a super bright and super sharp hdtv that you would like to try it on.

Brett, if the projected picture were to be viewed through a translucent screen, like a rear-projection TV, the upside-down position would be right. The Fresnel lens reverses the horizontal and vertical orientation of the image.

However, when used in the more-typical front-projection mode, the horizontal scan would, because of the lens, produce the picture reversed. This is the reason that the leads to the deflection coils that control 'raster' have to be reversed.
