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,

WARNINGS  
• 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.

Lamp Life  
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. SeeTable 1 0 :"OSD Messages" on page 21 and Table  
11: "Indicator Messages" on page 21.  
NOTE: 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.  
ViewSonic PJ501/PJ551

Replacing the Lamp  
When the indicator shows that there is zero (0) hours of lamp life remaining, the unit will  
automatically shut off within 10 minutes. If you see this message you should replace the lamp.  
However, you may replace the lamp anytime after the first warning message appears at  
approximately 300 hours of remaining lamp life.  
1 Switch the projector OFF, remove the power cord from the  
power outlet, and wait at least 45 minutes for the unit to  
cool.  
2 Prepare a new lamp.  
3 Check that the projector has cooled sufficiently, and gently  
turn it upside down.  
4 Loosen the two screws as shown in the diagram, and remove  
the lamp cover.  
5 Loosen the one screw, and gently remove the lamp while  
holding the grips. Touching the inside of the lamp case may  
result in uneven coloring.  
6 Install the new lamp and tighten the one screw firmly. Make  
sure that the lamp assembly is seated properly before  
replacing the other screw.  
7 Replace the lamp cover in position and tighten the two  
screws firmly.  
8 Gently turn the projector right-side up.  
CAUTION  
• Ensure that screws are tightened properly. Screws not tightened fully may  
result in injury or accidents.  
• Do not use the projector with the lamp cover removed.  
Figure 11: Lamp Replacement

replaced after the "THE POWER WILL TURN OFF AFTER 0hr." message is displayed, complete  
the following steps within 10 minutes of switching power ON. The power will be turned off  
automatically after 10 minutes.  
1 Switch POWER ON.  
2 From the OPTION menu select LAMP TIME with the description of "Adjusting the Projected  
Image".  
3 Press the RESET button and hold for approximately 3 seconds. The DEFAULT and CANCEL

Maintenance Inside the Equipment  
For safety reasons, ensure that the equipment is cleaned and checked by the dealer once every two  
years. Maintaining the equipment by yourself is dangerous.  
Cleaning the Lens  
Gently wipe the lens with lens cleaning paper. Do not touch the lens with your hands.  
Cleaning the Cabinet and Remote Control  
Gently wipe with a soft cloth. If dirt and stains are not easily removed, use a soft cloth dampened  
with water, or water and a neutral detergent, and wipe dry with a soft, dry cloth.  
CAUTION  
• Switch POWER OFF and remove the power cord from the power outlet before beginning maintenance work.  
• Make sure the lens is cool before cleaning.  
• Do not use detergents or chemicals other than those noted above. Do not use benzene or thinners.  
• Do not use chemical sprays.  
• Use a soft cloth or lens paper only.
