I took a can of compressed air and blew air into the larger openings. A nice cloud of dust and several puffs of air later, the tv turned on.

I solved this problem myself. You have to continue working with the housing until the connections meet just perfect. It was extremely frustrating but in the end I got it to work.

This unit does not have the usual lamp assembly that most do. On this unit the whole light engine has to be removed to replace the lamp assembly. Part number is LFS4000PA1 and cost is $1,351.95 @ www.partstore.com.

Check the fan that cools the bulb. It is directly behing the bulb. It should turn on when the power comes on. It apparently has a safety to protect your tv(and home). mine is in the process of going out. looking for online solutions as we speak.

fisrt, did you reset the lamp timer? if the projector turns on again, go into the menu settings and reset the lamp timer. 3 flashes also mean that the lamp is too hot. let the projector go through it's cooldown mode and shutdown before you unplug it. remove the filter case and vacuum or blow the dust out of the filter. you can also blow the dust out of the projector (if any) with canned air. lastly, be careful where you buy lamps from. you get what you pay for. cheaper isn't always better.
