Projector lamp replacement procedure

Projector lamp replacement procedure

Many of projector models contain lamp hour timer, which counts working hours of this component. Actually it counts working hours of projector. Lamp counter gives notification message when lamp life is going to end soon and it is displayed on screen soon after projector is switched. This message disappears after some minutes.

Lamp change is quit simple procedure what can be carried out by everybody who don’t want to spend extra money for installation guy visit and services.

Here are main steps of this procedure:
