Timing of replacing the lamp
When the Lamp indicator lights up red or a message appears suggesting it is time to replace 
the lamp, please install a new lamp or consult your dealer. An old lamp may cause a 
malfunction in the projector and in some instances the lamp may explode.
The Lamp indicator light and Temperature warning light will light up if the lamp becomes too hot. Turn 
the power off and let the projector cool for 45 minutes. If the Lamp or Temp indicator still lights up 
after turning the power back on, please contact your dealer. See Indicators on page 55 for details.
The following lamp warning displays will remind you to change the lamp.
StatusMessage
The lamp has been in operation for 3000 hours. 
Install a new lamp for optimal performance. If the 
projector is normally run with Economic selected 
(See Setting Lamp mode as Economic on page 
50), you may continue to operate the projector 
until the 3950 hour lamp warning appears.
The lamp has been in operation for 3950 hours. A 
new lamp should be fitted to avoid the 
inconvenience when the projector runs out of 
lamp time.
The lamp has been in operation for 4000 hours.
It is strongly recommended that you replace the 
lamp at this age. The lamp is a consumable item. 
The lamp brightness diminishes with use. This is 
normal lamp behavior. You can replace the lamp 
whenever you notice that the brightness level has 
significantly diminished. If the lamp is not 
replaced beforehand, it must be replaced after 
4000 hours usage.
The lamp MUST be replaced before the projector 
will operate normally.

							Maintenance 52
Replacing the lamp
• If lamp replacement is performed while the projector is suspended upside-down from the ceiling, 
make sure that no one is underneath the lamp socket to avoid any possible injury or damage to 
the human eyes caused by fractured lamp.
• To reduce the risk of electrical shock, always turn the projector off and disconnect the power cord 
before changing the lamp.   
• To reduce the risk of severe burns, allow the projector to cool for at least 45 minutes before 
replacing the lamp.
• To reduce the risk of injuries to fingers and damage to internal components, use caution when 
removing lamp glass that has shattered into sharp pieces.
• To reduce the risk of injuries to fingers and/or compromising image quality by touching the lens, 
do not touch the empty lamp compartment when the lamp is removed.
• This lamp contains mercury. Consult your local hazardous waste regulations to dispose of this 
lamp in a proper manner.
• To assure optimal performance from the projector, it is recommended that you purchase a BenQ 
projector lamp for lamp replacement.
1. Turn the power off and disconnect the 
projector from the wall socket. If the lamp is 
hot, avoid burns by waiting for approximately 
45 minutes until the lamp has cooled.
2. Loosen the screw on the lamp cover with a 
slotted screwdriver. 
3. Remove the lamp cover from the projector.
• Do not turn the power on with the lamp cover 
removed.
• Do not insert your fingers between the lamp and the 
projector. The sharp edges inside the projector may 
cause injuries.
4. Loosen the screw that secures the lamp.

							Maintenance 53 5. Lift the handle so that it stands up. Use the 
handle to slowly pull the lamp out of the 
projector.

scatter broken glass in the projector.
• Do not place the lamp in locations where water might 
splash on it, children can reach it, or near flammable 
materials.
• Do not insert your hands into the projector after the 
lamp is removed. If you touch the optical components 
inside, it could cause color unevenness and distortion 
of the projected images.
6. As shown in the figure, lower the new lamp 
first into the connector on the projector and 
align the two holes on the projector.
7. Tighten the screw that secures the lamp.
• Loose screw may cause a bad connection, which 
could result in malfunction.
• Do not over tighten the screw.
8. Ensure the handle is fully laid flat and locked in 
place.
9. Replace the lamp cover on the projector.
10. Tighten the screw that secures the lamp cover.
