B Replacing the Lamp
Replacing the lamp
When replacing the lamp, turn off the projector and unplug the AC cord. Wait 45 minutes so that the
lamp can cool. High-pressure lamp when hit, may explode if improperly handled.
Caution:
•
Dispose of used lamps in accordance with local authorities.
•
As the lamp is made of glass, do not apply shocks to it or scratch it.
•
Also, do not use an old lamp, as this could cause the lamp to explode.
•
If it seems that the lamp has exploded (for example, an explosive sound is heard), disconnect the power
cord from the outlet and ask your dealer to replace the lamp. The lamp is covered by a front glass
panel and an air-tight structure, but, in rare cases, the reflector and the inside of the projector may be
damaged by scattered, broken pieces of glass, which could cause injury while being handled.
i.
Turn the main power switch off and disconnect the power cord from the outlet.
ii.
Remove the lamp cover.
If hot, the lamp could cause burns. Wait for about 45 minutes until lamp has cooled down.
•
Loosen a screw and remove the cover.
•
iii.
Loosen the screw and pull the handle to remove the lamp.
If the screw is not loosened completely, you could hurt your fingers.
•
Do not insert your hand into the box after the lamp has been removed. (There are optical parts
•
inside that, if touched, could result in color unevenness, etc.)
iv.
Replace the lamp with a new one and fix it using the same screw.
Firmly tighten the lamp screw. Loose screws could result in a poor connection, which could cause
•
the unit to malfunction.
v.
Install the lamp cover and fix it using a screw.
To prevent burns, install the lamp cover and secure it using the screw.
•
Do not turn on power with lamp cover removed.
•
Whenever the lamp is replaced, reset the total operation time of the lamp. Do not reset if the
•
lamp has not been replaced.
Do not reset the timer without changing the lamp, as this can cause the lamp to break.
