Lamp Replacement

Caution

To reduce the risk of electrical shock, always turn off the projector and disconnect the power cord before changing the lamp.

1.Press the POWER button to turn the main power switch off and disconnect the power cord from the outlet.

2.Loosen the screw and remove the lamp cover. If the lamp is hot, avoid burns by waiting 45 minutes until the lamp has cooled.

3.Loosen the 3 screws indicated by the arrows below. (It is strongly recommended to use a magnetic-headed screwdriver, if possible. Pull the handle to remove the lamp housing. If the screws are not loosened completely, they could damage your fingers. Do not insert your hand into the box after the lamp is removed. If you touch the optical parts inside, it could cause color unevenness, etc.

4.Replace the lamp with the new one, insert it in the projector, and tighten the screws. Firmly tighten the lamp screws. Loose screws may cause a bad connection, which may result in a malfunction.

5.Re-install the lamp cover and tighten the screw. Do not turn on the power with the lamp cover removed. Whenever the lamp has been replaced, reset the total operation time of the lamp. Do not reset if the lamp was not replaced, as this could cause breakage.
