cool cool that seems pretty straight forward.
didn't work for me
/edit
ok tried it again, it works, sort of, the projector is functioning (if I put my flashlight where the LD's were and look through the lens I can see my desktop) BUT, the red LED will not light... any suggestions?

What color was your desktop while looking through the lens with a flashlight? im curious to see if the LCD is responsible for any color adding in this system ,if it is them perhaps we can still use a white HP led. i know the single LCD systems are rather easy to get a projection out of..take for example the virtually un-findable Citizens Mini projector circa 1990-1991...a single LCD with like a hardware store lightbulb behind it..or the Phillips LCP 5200 circa 1990-94 both very straight forward projectors with a single LCD and much like a hardware store flood lamp behind them. Im almost certain this can be done with the casio XJ-a...
there is definitely some stuff going on with the dichros/filters...
theres no LCD as this is a DLP projector
I used a 3W LED flashlight pointed into the LD mirror and while looking into the lens to see the output I had shades of white/blue/green
I was running a test pattern (google testpat.exe, its from IBM, thats what I was using)
Wow no LCD?.
then cany anyone idtenitf this peice..its from a this websight which shows acomplete tear down of the projector

DLP chip with PCB.

Ok but light still passes through it to create the projection correct?
Nope, it's actually a mirror, a controlled array of 800.000 of mirrors.

i was wondering since it uses a Phatlight Led for the red...would it be possible to run a blue phatlight led (and hope the phosphor wheel makes some green light) or just run a phatlight blue and phatlight green to complete the RGB color "gamut" i think is the word. Im exploring all avenues of LED light at this moment.from Phatlight LEDS to Luxeon Rebels,to the HiPow Chinese cartridge style LED's... Also does the wavelength of the Blue Lasers have an important bearing on it? like will the phosphor wheel only do its job when a 445nm Blue/IR/UV laser hits it? or will any blue light source suffice as long as it get through the lens gauntlet and into the DLP chip?
