Viewsonic PJ501 Manual De Usuario

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.   

After replacing the lamp, it is important that you reset the lamp timer. When the lamp has been 
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.

Switch POWER ON.

From the OPTION menu select LAMP TIME with the description of "Adjusting the Projected 
Image".

Press the RESET button and hold for approximately 3 seconds. The DEFAULT and CANCEL 
options will display.

Press the Up arrow button to select the DEFAULT. The remaining lamp life is now reset to 2000 
hours. 

Do not reset the lamp timer without replacing the lamp. The message functions will 

not operate properly if the lamp timer is not reset correctly.

Switch the projector OFF, remove the power cord from the 
power outlet, and wait at least 45 minutes for the unit to 
cool.

Prepare a new lamp.

Check that the projector has cooled sufficiently, and gently 
turn it upside down.

Loosen the two screws as shown in the diagram, and remove 
the lamp cover.

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.

Install the new lamp and tighten the one screw firmly. Make 
sure that the lamp assembly is seated properly before 
replacing the other screw.

Replace the lamp cover in position and tighten the two 
screws firmly.

Gently turn the projector right-side up.

• 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.
