All the heat inside the housing causes the sensor to fail. I changed out the sensor, and my set works great. Next step is to modify color wheel cover for better cooling. I can give you more details how to test this, but it is a bit of work.
*** I see that you were able to get inside and clean your color wheel or replace the sensor. I have tried to remove the light engine and clean the color wheel, but there is something holding it in near the back left of the light engine... I can't get this thing out to save my life. If I could do that, I could follow the steps to clean it and re-install it.... I really believe this is the fix I need... I just need assistance with how to remove the light engine.
I see it's been a while since this was posted... I hope you respond.
Thanks in advance!
