ELPLP68 lamp replacement and lifetime  

Replacing the ELPLP68 lamp

When replacing the ELPLP68 lamp because it has stopped illuminating, there is a possibility that the lamp may be

broken. If replacing the lamp of a projector that has been suspended from the ceiling, you should always

assume that the ELPLP68 lamp is cracked, and remove the lamp cover with care. When you open the lamp cover,

small shards of glass could fall out. If any shards ofglass get into your eyes or mouth, contact a doctor

immediately

After replacing the ELPLP68  lamp, make sure you reset the lamp hours.

The projector records how long the lamp is turned on and a message and indicator notify you when it is time

to replace the lamp.

• The lamp replacement message is set to appear after 3900 H in order tomaintain the initial brightness

and quality of the projected images. The message display time changes depending on the usage

situation, such as the color mode setting and so on.

If you continue to use the lamp after the replacement period has passed, the possibility that the lamp

may explode increases. When the lamp replacement message appears, replace the lamp with a new

one as soon as possible, even if it is still working.

• Depending on the characteristics of the lamp and the way it has been used, the lamp may become

darker or stop working before the lamp warning message appears. You should always have a spare

lamp unit ready in case it is needed.
