I found no service available for another make as well and we ended up replacing the unit. Similar life span!
We've been using a BenQ PB8263 DLP Projector for two years. The projector bulb has approximately 2500 out of 3000 hours. We are now running into issues where the projector is shutting down due to a thermal issue. We removed the face plate and blew whatever dust was inside. The air filters have been routinely cleaned monthly. I've seen an article on line for a different projector which suggested replacing a thermosensor. How would one do that? Any thoughts on solving the thermal issue?
