Look at this.


What are they talking about? At first I though this was like the E Homes that have the CRT's factory alligned and project out of one lense, you know the ones I mean.


But they say there throwing in a new bulb. WHAT?

Me thinks the seller isn't sure what he's got. It is obviously a bulb based unit and maybe he threw the word CRT in there to garnish a little more interest. Worked huh? Course he says that you'll have to align the 3 colors. Or maybe they were using it like one of out forum members was a few months ago...a generated convergence grid to align their CRT to!

me thinks it's a 3 chip LCD projector ...(one LCD panel for each color)

Good luck!

in short, it uses a CRT to create the image and then project it onto an Amorphous LCD (also called the Image Light Amplifier) and using a polarization scheme, it then becomes a type of reflective LCD with no matrix. SO it is an early version of what is now D-ILA. I cannot recall the model number though. if it works and you can figure out how to set it up, it should look killer.

I believe this JVC system is an ILA system - the forerunner to the D-ILA.


Whereas the D-ILA uses a pixelated mirror that is driven directly by the control electronics - hence the "D" for

"direct-drive" in the acronym - the ILA uses a CRT to write on a layer of amorphous silicon. The voltage thus produced

is applied to the non-pixelated mirror, and hence the liquid crystal chip; and is used to control the state of the liquid

crystal chip.


Light from a Xenon lamp is modulated by the 3 ILA chips - one for each color - recombined, and then projected.


The JVC ILAs have 3 CRTs, 3 ILA chips and one Xenon lamp.

Very interesting.................


Im not bidding though..................

When set up correctly, that thing looks better than alot of the really high end machines. It would give a great result, especially if treated as a project. (and you don't invest too much in it.)
