    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.
    Go to http://www.benq.com for a replacement lamp.
    The Lamp indicator light and Temperature warning light will light up if the lamp becomes too 
    hot. Turn the projector 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 65 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. 
    StatusMessage
    Install a new lamp for optimal performance. If 
    the projector is normally run with Economic 
    selected (See Setting Lamp mode as Economic 
    or SmartEco on page 60), you may continue to 
    operate the projector until the next lamp 
    warning appears.
    Press MODE/ENTER to dismiss the message.
    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.
    Press MODE/ENTER to dismiss the message.
    The lamp MUST be replaced before the 
    projector will operate normally.
    Press MODE/ENTER to dismiss the message. 
    						
    							Maintenance 62
    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.
    • 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 wall socket. If the lamp is 
    hot, avoid burns by waiting for approximately 45 minutes until the lamp has cooled.
    2. Loosen the captive screws from the left 
    and rear side.
    3. Remove the lamp compartment cover 
    as shown.
    4. Disconnect the lamp connector from 
    the projector as illustrated. 
    						
    							Maintenance63
    5. Loosen the two captive screws that 
    secure the lamp.
    • 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.
    6. Lift the handle so that it stands up. Use 
    the handle to slowly pull the lamp out 
    of the projector.
    • Pulling it too quickly may cause the lamp to 
    break and 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.
    7. Insert the new lamp into the lamp 
    compartment and make sure it fits in 
    the projector.
    • Ensure the connectors are aligned.
    • If you experience resistance, lift the lamp 
    and start again.
    8. Tighten the screws that secure the 
    lamp.
    9. Ensure the handle is fully laid flat and 
    locked in place.
    • Loose screw may cause a bad connection, 
    which could result in malfunction.
    • Do not over tighten the screw. 
    						
    							Maintenance 64
    12. Restart the projector.
    Do not turn the power on with the lamp cover removed.
    Resetting the lamp timer
    13. After the startup logo, open the On-Screen Display (OSD) menu. Go to the 
    SYSTEM SETUP: Advanced > Lamp Settings menu. Press MODE/ENTER. 
    The Lamp Settings page displays. Highlight Reset lamp timer. A warning 
    message displays asking if you want to reset the lamp timer. Highlight Ye s and press 
    MODE/ENTER. The lamp time will be reset to 0.
    Do not reset if the lamp is not new or replaced as this could cause damage. 
    10. Connect the lamp connector properly 
    and place as drawing before lamp 
    compartment cover installation back.
    • Lamp connector must be installed flush 
    with the connector base as shown in the 
    image below. A gap between the lamp 
    connector and the connector base will 
    cause damage to the projector. The 
    following images illustrate correct and 
    incorrect lamp connector installations.
    11. Replace the lamp compartment cover 
    on the projectorand tighten the 
    captive screw.
