Viewsonic PJ501 Manual De Usuario

To order a new lamp unit see page 26 for contact information and see Table 15 for part numbers. The 

estimated lamp life is 2000 hours. Before replacing the lamp, turn the Power Switch OFF, remove 

the power cord from the power outlet, and wait approximately 45 minutes until the lamp has cooled. 

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

   

Projector lamps have a finite life. The image will become darker and hues will become weaker after 

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

Replace the lamp if the LAMP indicator is red or the “CHANGE THE LAMP” message appears 

when the projector is switched on. See Table 10: "OSD Messages" on page 21 and Table 

11: "Indicator Messages" on page 21.

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

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

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

  

  

• Dispose of the used lamp according to local regulations.
• 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.
