This information is useful when contacting Technical Support. 48 MAINTENANCE & TROUBLESHOOTING This section describes how to: • clean the lens •replace the projection lamp • clean the projection lamp filter screens • replace the batteries in the remote control •troubleshoot the projector Cleaning the Lens Follow these steps to clean the projection lens: 1 Apply a non-abrasive camera lens cleaner to a soft, dry cloth. • Avoid using an excessive amount of cleaner. Do not apply the cleaner directly to the lens. • Do not use abrasive cleaners, solvents or other harsh chemicals that can scratch the lens. 2 Lightly wipe the cleaning cloth over the lens in a circular motion. 3 If you do not intend to use the projector immediately, replace the lens cap. Replacing the Projection Lamp The lamp hour counter in the Status menu counts the number of hours the lamp has been in use. After 1,980 hours of use, the message "Change Lamp" temporarily appears on the screen when the projector is turned on. Change the lamp within the next 20 hours. After 2,000 hours, the lamp will not light. You can order new lamp modules from your Toshiba dealer. See "Accessories" on page 62 for information. Follow these steps to replace the projection lamp: 1 Turn off the projector and unplug the power cord. 2 Wait 30 minutes to allow the projector to cool thoroughly. WARNING: Never attempt to replace the lamp before turning off the projector and unplugging the power cord. Always wait 30 minutes or more after the projector is turned off and unplugged before opening the lamp door. Failure to follow these instructions could result in burns, electric shock and/ or serious bodily injury. 49 Maintenance & Troubleshooting 3 Turn the projector over on a soft flat surface. Push the ridge on the lamp door toward the back (Figure 39). The arrow on the lamp door should point to the unlock icon on the bottom of the projector. Lift the door up. WARNING: Be extremely careful when removing the lamp module. In the unlikely event that the bulb ruptures, small glass fragments may be generated. The lamp module is designed to contain these fragments, but use caution when removing the lamp module. CAUTION: Never operate the projector with the lamp door open or removed. This disrupts the air flow and causes the projector to overheat. FIGURE 39 Removing the lamp door 4 Loosen the two non-removable screws on the outside of the module (Figure 40). FIGURE 40 Loosening the screws on the lamp module 50 5 Lift and grasp the metal bail wire and lift the module out (Figure 41). Dispose of the lamp module in an environmentally proper manner. FIGURE 41 Removing the lamp module 6 Install the new lamp module, being sure to align the connectors properly. 7 Push the module in until it is flush with the bottom case of the projector. 8 Tighten the screws on the outside of the module. 9 Replace the lamp door by inserting the hooks on the lamp door into the slots on the projector and pressing the lamp door into place. The arrow on the lamp door should point to the lock icon on the bottom of the projector. If the lamp door does not fit properly or bulges out, remove the door and reseat the lamp module. 10 Plug in the power cord and press the green power button to turn the projector back on. 11 To reset the lamp hour counter in the Status window, press and hold the volume - button, and then press the source button (while still holding down the volume - button) for 5 seconds. Verify that the counter was reset by viewing the counter in the Status window. WARNING: Do not drop the lamp module or touch the glass bulb! The glass may shatter and cause injury. Maintenance & Troubleshooting Cleaning the Projection Lamp Filter Screens In dirty or dusty environments, the dust filter screens on the lamp module can become clogged, causing high temperatures inside the lamp module. These high temperatures can cause premature lamp failure. Routine maintenance to remove dust and dirt from the screens lowers the lamp operating temperature and prolongs lamp life. To maximize lamp life, clean the screen every 250 hours. 1 Remove the lamp module. Refer to "Replacing the Projection Lamp" on page 49 for instructions. 2 Examine the dust filter screens on each side of the lamp module. If necessary, use a vacuum cleaner set on low power to clean the screens. Use a cotton swab dipped in isopropyl alcohol to lightly wipe each screen. After you have wiped each screen, blow away any remaining contaminants.
