Damm, thought for sure that would help you. Sorry I, personally couldn't help more.
I informed him of your suggestion today with regards to the indexing of the color wheel. He said he was not aware of that and he would need to speak to NEC about it and would get back to me.....
said he will not change part until he looks into color wheel indexing...

I purchased my projector about a year ago "Used".
used very frequently. I recently changed the bulb and about a month later i began to get some flickering along with some picture quality loss. the video quality would at times resemble a computer screen in safe mode "best way I could describe it" I located an authorized nec shop in my area. Initialy they said it was my formator board. a week later when i went to pick it up they said it was a color sensor and my color wheel was dirty......
about three months later i am having the same problem. I am considering buying the HT1100 "new" but wanted to see if there is anyone can help or anything i could do....

Sorry for the long post here -- but this question requires a bit of background ...
I purchased a used HT1000 and installed into my home theater around Jan of 2004. I've been really pleased with the overall performance, and it ran smoothly for a little over a year, but then it started to develope two major visual problems:
1) a solarizing, or clipping of the highlights that got progressively worse over time. I could improve it by recalibrating the video settings, but it eventually became unsolvable.
2) after the projector warmed up the image would start to flicker and bounce. Frames would flash on that would be offset by a full half of a screen height, or cut into various banded chunks, and other nasty visual aritfacts that made it impossible to watch. This problem was at first only noticable in ECO mode, and would go away when I put the projector into full power mode. I presumed that it was related to heat, and that the higher fan speed in full power mode was helping to resolve it. Eventually however, even full speed mode deteriorated to an unwatchable state. This problem appeared when using any input of the projector.
Since it was without warranty, I ended up paying to get the projector repaired at an NEC authorized repair shop at a cost of around $800. I also replaced the lamp at this time as it was getting close to due. After the repair, both problems were solved completely, and the unit worked great -- until now, almost one year after the repair.
I'm not having any reoccurance of the first problem (clipping and solarization), but the flickering problem is coming back. My guess is that within 2-4 weeks the projector will be unusable again. This is beyond the warranty of the repair, and I expect that I'm looking at another several hundred dollars to fix it -- or drop a bigger chunk of cash to by a new one.
So .... my question is - has anyone else had any similar kinds of problems with their HT1000 or HT1100? (I'm considering the HT1100 as a replacement). I'm very happy with the projector other than this problem - and it still seems the best bang for the buck at it's price point (HT1100 MSRP being $1,995). What I would really hate to do, is buy a new HT1100, and have this problem again in 1-2 years.
PS - Ambient operating temperature in the home theater room is between 68-75 degrees typically. It sometimes gets warmer (i.e. 78), but I would hope that this would not be a problem for the projectors operating environment.
