When the ALARM indicator is blinking: ● Action 1. Pull out the power plug from the power outlet. 2. Install the air filter correctly. * If the LAMP indicator is also blinking, replace the lamp unit a new one. (See page E-42, "Replacing the Lamp unit.
● When the Power Supply Stops (All Indicators Remain OFF When Power Switch is ON) ❍ Action 1. Pull out the power plug from the power outlet. 2. Check the following and take the necessary steps to alleviate the problem. Ambient temperature is more than 35°C/95°F. Vent holes are blocked. Lamp unit cover is not securely in place. Problem in internal circuitry. E-44 Place your projector in an area having an ambient temperature of 0°C/32°F to 35°C/95°F.
Maintenance ■Replacing the Lamp unit The life of the lamp used on this projector is 1400 hours.(This may shorten due to the conditions of use.) The lamp is designed to forcibly turn off in the case of a lamp possibly breaking if it is used beyond the lamp usage of 1500 hours. When the lamp is used for 1400 hour or more, replace the entire lamp unit (sold separately) in the following instances.
2 Loosen the lamp screws. Loosen the screws of the lamp unit. 3 Remove the lamp unit. Grasp the lamp unit handle and lift it out of the housing. 4 Install a new lamp unit. q Push the lamp unit inside while holding the handle. w Check that the three protrusions for position making are inserted securely in the three holes. e Tighten the lamp unit cover fixing screws. r Install the lamp unit cover and tighten the lamp unit cover fixing screw. Be sure to tighten the screws.
Maintenance ■ Cleaning the Air filter The air filter keeps the optical components of your projector free from dust and dirt. Dust or dirt on the air filter can cause heat to build up inside your projector, resulting in the increase of the fan speed. This, in turn, may reduce lamp life or result in damage to internal components. The filter should therefore be cleaned regularly (approximately once a month if the projector is used for about four hours a day.
Troubleshooting If you think a fault has occurred, check the following table and take the required action. Problem Projector does not turn on The projector lamp does not light. Check These items See Page • The power cable is disconnected. E-18 • The lamp unit cover has not been replaced. E-45 • The lamp is blown. E-45 • The air filter has not been replaced.
