I would give Epson tech support a call. It is not typical of these models to have issues, but all manufacturers certainly run into some problems, and they can often be taken care of at a repair facility. No, not ideal to drop a few hundred bucks getting it fixed, but if the iris has gone bad, then that may be necessary. I know I recently had this repair done on a Panasonic AX200 projector. A few hundred bucks and it was back up and running just like new.
