Toshiba DLP help

It sounds so easy... Open up the unit, gently twist off the color wheel segments, take out the UV filter, put it back together.

After about 50 screws I think I may have found the color wheel, but I don't see a lot of colors. Is there another type of wheel? OH wait, that is the color wheel.

Is that a UV filter before the color wheel? I think it is, I see a purple'ish coating on it. I took it out.

This is going to be interesting.

Update: back together, no light from the bulb. I'm wondering what I did wrong.

I'm getting a flashing orange lamp light. I'm guessing my bulb is out. Is there anything else I can check?

Make sure all your cables are plugged back in correctly. My Infocus projector had a switch that detected when the cover was removed. Also make sure you lamp is plugged back in.

my sympathies with the toshiba, I have one, it took ages just to get to the inards, I decided not to use it for sla, but a structured light scanner instead.
old HP6120 type dlp are a dream to work on, bigger, older, and maybe lower resolution, but excellent for hacking, I bought 3 at £5 each plus shipping, 2 had working bulbs, the one with the brocken bulb is the one I am hacking. the circuit boards are benQ, so maybe they are good also.

After a lot of tinkering, I got the projector to come back on. It wasn't the lamp door switch.

From the best I can tell it was a hidden board connector. On the bottom of the Toshiba main board, there was a connector that needed seated to the DLP below. at least I think it is a connection to the DLP. I couldn't find anything else that was wrong. I was even careful and took pictures as I dissembled, I totally missed it.

With the color wheel out, I know I'll only get a black and white image, but right now it just looks like fuzz.

One step closer.
