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.
Do not attempt to replace the lamp yourself. Contact the qualified service personnel for 
replacement.
The Lamp indicator light and Temperature warning light will light up if the lamp becomes too 
hot. See Indicators on page 66 for details.
The following lamp warning displays will remind you to change the lamp.
The warning messages below are for reference only. Please follow the actual on-screen 
instructions to prepare and replace the lamp.
XXXX shown in the above messages are numbers that vary depending on different models.
StatusMessage
Install a new lamp for optimal performance. If the 
projector is normally run with Economic 
selected (Setting Lamp mode eco function as 
Economic or SmartEco mode on page 60), you 
may continue to operate the projector until the 
next lamp warning appears.
A new lamp should be fitted to avoid the 
inconvenience when the projector runs out of 
lamp time.
It is strongly recommended that you replace the 
lamp at this stage. 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.
The lamp MUST be replaced before the projector 
will operate normally. 
						

							Maintenance 63
Replacing the lamp
•Hg - Lamp contains mercury. Manage in accordance with local 
disposal laws. See www.lamprecycle.org.
• 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.
• Ensure good ventilation when handling broken lamps. We recommend that you use 
respirators, safety glasses, goggles or face shield and wear protective clothing such as gloves.
1. Turn the power off and disconnect the projector from the power outlet. If the lamp 
is hot, avoid burns by waiting for approximately 45 minutes until the lamp has cooled.

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 screws that secure the 
lamp.
5. Lift the handle so that it stands up. Use 
the handle to slowly pull the lamp out

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.
