ViewSonic  PJ750

To order a new lamp unit (Lamp Part # PRJ-RLC-001), contact ViewSonic or your dealer. For the 

lamp part number, see the Optional Parts in the Specifications in this guide. For contact information, 

see the Customer Support table in this guide. Before replacing the lamp, turn the Power Switch OFF, 

remove the power cord from the power outlet, then wait approximately 45 minutes until the lamp has 

cooled.

CAUTION: The lamp may explode if handled at high temperatures.

WARNINGS:

• Dispose of the used lamp according to local regu-

lations.

• Since the lamp is made of glass, do not drop the 

unit and do not scratch the glass.

• Do not reuse the old lamp. This could cause the 

lamp to explode.

• If it is probable that the lamp has exploded (you 

have heard an explosive sound), disconnect the 

power plug from the power outlet and ask your 

dealer to replace the lamp. The lamp is protected 

by a cover glass, but in rare cases the reflector 

and the inside of the projector could be damaged 

by broken or shattered glass. Broken pieces of 

glass could cause injury.

• Do not use the projector with the lamp’s front 

glass covering removed.

Projector lamps have a finite life. The projected images will become darker and hues will become 

weaker after a lamp has been used for a long period of time.

The LAMP indicator also becomes red when the lamp unit reaches a high temperature. Before 

replacing the lamp, switch the POWER OFF, wait approximately 20 minutes, then switch the 

POWER ON again. If the LAMP indicator still displays red, replace the lamp.
