Projector keeps shutting off

I start my 3M Digital Media System-projector, and for a couple of seconds, the screen appears as it should. Then it switches to black, but doesn't turn off. I recently replaced the lamp. Any ideas?

SOURCE: Shutting down after 2 min

call panasonic-- they have extended the warranty on this issue up to 18 months, as it is a known problem with the sealant for the iris. If the sealant is not moving, the iris sticks and the projector goes into lockdown. Call this number and they will take care of your problem: 1-800-211-PANA (7262)
