Disassembly Lamp Module - ViewSonic Pro8400 Series VS13647 Service Manual

3.4 Disassembly Lamp Module

As the projector operates over time, the brightness of the projector lamp gra dually decreases
and the lamp becomes more susceptible to breakage. We recommend replacing the lamp if a
warning message is displayed.
Note:
The lamp is extremely hot right after turning off the projector. If you touch the lamp, you
may scald your finger. When you replace the lamp, wait for at least 45 minutes for the
lamp to cool down.
Wear protective gloves and eyeglasses when fixing or detaching the lamp.
Do not operate the lamp in proximity to paper, cloth, or other combustible material nor
cover it with such materials.
