Benq W7000 - W7000+ - How to replace the projector lamp – How to reset the lamp hour – How to extend lamp life – Projector repair and service

Getting to know the lamp hour

when the projector is in operation, the duration (in hours) of lamp usage is automatically calculated by the built-in timer. The method of calculating the equivalent lamp hour is as follows:
Equivalent lamp hour = 1 (hours used in Economic mode) + 3/2 (hours used in Normal mode)
To obtain the lamp hour information:
1. Press MENU and then press < / > until the Advanced Setup menu is highlighted.
2. Press Down to highlight Lamp Settings and press ENTER. The Lamp
Settings page displays.
3. The lamp hour information is shown in the row of Equivalent Lamp Hour.
4. To leave the menu, press MENU.
Extending lamp life
The projection lamp is a consumable item. To keep the lamp life as long as possible, you can do the following settings via the OSD menu.
Setting Lamp Power as Economic
Using Economic mode reduces system noise and power consumption. If the Economic mode is selected, the light output will be reduced and result in darker projected pictures.
Setting the projector in Economic mode also extends the lamp life. To set Economic mode, go to the
Advanced Setup > Lamp Settings > Lamp Power menu and press < / > .
Setting Auto Off
This function allows the projector to turn off automatically if no input source is detected after a set period of time.
To set Auto Off, go to the System Setup > Auto Off menu and press < / > to select a time period. The time period can be set from 5 to 30 minutes in 5-minute increments. If the preset time lengths are not suitable for your presentation, select Disable. The projector will not automatically shut down in a certain time period.
Timing of replacing the lamp
When the Lamp indicator lights up red or a message appears suggesting it is time to replace the lamp.
The following Lamp warning displays will remind you to change the lamp.
# Install a new lamp for optimal performance. If the projector is normally run with Economic selected you may continue to operate the projector until the next hour lamp warning appears.
Press ENTER to dismiss the message.
# 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.
Press ENTER to dismiss the message
# The lamp MUST be replaced before the projector will operate normally.
Press ENTER to dismiss the message
Replacing the lamp
# To reduce the risk of electrical shock, always turn the projector off and disconnect the power cable 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.
1. Turn the power off and disconnect the projector from the power outlet. Turn off all connected equipment and disconnect all other cables.
2. Slightly lift the projector up. Loosen the screws on the lamp cover (located on the left side)
3. Remove the lamp cover.
4. Loosen the screws that hold the lamp to the projector. If the screws are not loosened completely, they could injure your fingers.
5. Lift the handle so that it is perpendicular to the lamp. Use the handle to slowly pull the lamp out of the projector.
Notes
# Pulling it too quickly may cause the lamp to break and scatter broken glass in the projector. To reduce the risk of injuries to fingers and damage to internal components, use caution when removing lamp glass that has shattered.
# Do not place the lamp in locations where water might splash on it, children can reach it, near or above heat sources, or near flammable materials.
# Do not insert your hand into the projector when the lamp is removed. If you touch the optical components inside, it could cause blurred images.
