When an Indicator is Lit or Blinking The indicators on the projector’s control panel lit or blink to notify of problems, as described below. An indicator is also used to notify you of the currently set power mode (under normal circumstances). See “Power Cable Connections and Switching the Power On/Off” on page E-21.
Troubleshooting Check the following matters before requesting servicing. Problem Power does not turn on Reference Page Check • Is the power cord plugged into a power outlet? • Is the lamp cover properly mounted? • Is the projector’s temperature high? To protect the projector, the power cannot be turned on when the projector’s temperature is abnormally high.
Cleaning • Be certain to disconnect the power plug from the power outlet before cleaning. • Do not spray or otherwise expose the projector, lens, or screen to volatile substances such as insecticides. Do not leave rubber or vinyl products in contact with the projector for long periods. Doing so could cause them to undergo qualitative changes or the coatings may peel, etc. Cleaning a Soiled Projector Main Unit • Wipe with a lint-free, soft, dry cloth.
Replacing the Lamp Cartridge • The lamp that is used as a light source in the projector has a limited service life. The rated service life of the lamp is about 1500 hours (when used in normal mode only). This could be shortened depending on conditions of use and other factors. Note that lamp life will be extended when the projector is often used in Eco mode.
Replacing the Lamp Cartridge Preparations: Turning the projector upside-down on top of a soft cloth, etc., so that it does not get scratched makes it easier to replace the lamp cartridge. Turn the projector right-side up after replacing the lamp cartridge. 1 Unplug the power cord. 2 Turn the projector upside-down. 3 Remove the lamp cover. (1) Turn the lamp cover’s set screw counterclockwise and loosen until the screw turns freely. (The screw does not come off.
Replacing the Lamp Cartridge 5 Mount the new lamp cartridge. (1) Place the lamp cartridge with its socket facing to the right and push it in slowly. (Line it up with the screw holes in the projector.) (2) Turn the two lamp cartridge screws clockwise to tighten them. 6 Mount the lamp cover. (1) Set the tip of the lamp cover in place, then close the lamp cover. (2) Turn the lamp cover’s screw clockwise to tighten it. 7 Reset the Lamp Timer. Connect the power cable, switch on the power, and then reset.
