Replacing the Light-Source Lamp
The light-source lamp has its service life. It is approximately 1000 hours.
When the light-source lamp approaches the end of its service life, its degradation progresses rapidly. When the lamp’s used
hours exceed 900 hours, the projector’s LAMP indicator comes on. Also, at the start of projection (lamp energized), the message
“REPL.-LAMP” appears on the projection screen for about two minutes. Then, replace with a new light-source lamp, or arrange
for a replacement lamp. When lamp’s service has reached 1000 hours, the projector’s LAMP indicator starts blinking, and if you
press the OPERATE button (or press the remote control’s OPERATE button for more than one second), the light-source lamp
does not turn on. The specified lamp replacement period is 1000 hours, but depending on use conditions, the replacement
period may vary. If video image is dark and its color tint is extraordinary even after you have adjusted color tint and brightness,
replace the light-source lamp a little earlier.
Purchase new light-source lamps (part No. : G1000-LAMP) from the authorized dealer where you have purchased the projector,
or consult the Service center.
CAUTIONS and NOTES
• If the projector is set up in a tight place which is unsuitable for work, and if you perform replacement work there, this could hurt
you. Move the projector to a place wide enough for work, and then replace the lamp.
• Use a genuine product for the light-source lamp. If you use other than a genuine product, this could cause a malfunction. Also,
never use an old light-source lamp. An old lamp could cause marked degradation in performance or explode itself, possibly
causing the projector to malfunction. Also, its broken pieces could come out of the projector and harm you when replacing the
light-source lamp.
• Do not replace the light-source lamp immediately after the projector has been used. The temperature of the light-source lamp
is still high and could cause a burn. Be sure to allow a cooling period of one hour or more before performing replacement work.
• Before starting lamp replacement work, turn off the MAIN POWER switch (see page 26), and disconnect the power cord from
the wall outlet. If you perform the replacement work with the power cord left connected, this could cause harm or electric
shock.
• Never discard an old light-source lamp (used lamp), as is. Otherwise, this could involve a great danger. The lamp contains a
xenon gas inside, which is applying a high pressure. If the gas is not removed, it could cause the lamp to explode.
For handling used lamps, refer to the manual supplied with the new replacement lamp you have purchased. If you have any
questions, consult a authorized dealer where you have bought the replacement lamp or Service center.
