The light engine slides into a preset position. I had to remove the lamp power supply to get to the color wheel housing to take it off. Where would the light engine screw be located?
The wheels are identical. There is a board that had to be removed which the wheel, RPM sensor and data cable plug into. Is this the DMD board or is it on the light engine itself? I didn't open the light engine itself, only removed and replaced the wheel. The wheel is centered on the light pipe (square fiber optic).
I am at a loss, where are these screws physically located?
That is the one with the big heat sink. No it remained in the set, but I do recall it has three (maybe four) allen screws. are these the ones you are referring to, maybe for X, Y and Z adjustment?
I will try that tonight. Maybe that heat sink got bumped re-installing the light engine. If I am correct, then the top screw will move the picture down and the bottom will move it up (reversed as it is a reverse mirror image). I will let you know.
