I installed 2 NEC PA500 projectors in a church. This is installed using a local area network and the projectors both use wireless and wired LAN. One of the projectors is having a problem when switched on, it does not throw the picture up on the screen. When I logged onto the projector through its IP address, a fault report appeared which mentions that the iris is not working. Please help ASAP.
