There are only two brackets that hold the LE tray in place the L-Bracket on the left with two screws on each surface and then the other L-Bracket just to the right of the Lamp with four little screws. The LE tray can only be removed if you completly remove the bracket on the right.
This seems to be the problem.
Right now it seems like if you leave the TV off for an extened period of time it will turn back on for a short while.
Shows a thermal related problem.
I thought about bench testing as well, but could not think of a way to do it. If I can get power to it and it spins then one assumes it is a controler issue?
Can you find the connector to that fan? If so, disconnect it and see if you can apply separate power to it. If the fan does work/turn, is it a three wire connector or two? if three, then it might be a return signal issue, or as you said, a control circuit problem.
Any idea where I could get the alignment pattern?

I am not sure exactly what you would call this but it is the relfector mirror on the last projector housing before it is projected onto the Ferenzial Lens.
You had that in your hand, it's just a mirror.
