BenQ W1080ST DLP Projector Cleaning / Service P2

Re-assembling and testing a BenQ W1080ST DLP Video Projector.
This had a lamp problem and some dust/smoke buildup. I ended up running this for almost 24 hours (8 per day) before shipping it. The Color Wheel sensor looked clean but had a light film of smoke/tar buildup from a nearby fireplace in the room it is used in. Not a bad projector. Thanks for watching.
