Replacing the Projection Lamp

The lamp hour counter in the menus counts the number of hours the lamp has been in use. The LP 740 uses a metal halide bulb. These types of bulbs deteriorate over time. Replace the lamp when the brightness is no longer acceptable. The lamp LED blinks slowly after 950 hours; it blinks more rapidly after 1000 hours. You can order new lamp modules from your In Focus dealer. See “Accessories” on page 34 for information.

Follow these steps to replace the projection lamp:

1Turn off the projector and unplug the power cord.

2Wait 30 minutes to allow it to cool thoroughly.

3Place the projector on its side, then remove the 2 screws on the lamp module door (Figure 16).

4Pull the lamp door up and remove it.
