Alright, another projector fixed! The new lamp from Projectorlamps.com slid right into the Optoma TX665UST-3D like it was made for it, which, of course, it was. Seriously, couldn't have been an easier install, and the picture is bright and clear again, so the teachers are happy. No more squinting in the back row!
