Replacing the Light-Source Lamp
The light-source lamp has its service life. It is approximately 1000
hours.
When the lamp’s used hours exceed 900 hours, the projector’s LAMP indicator
comes on. Whenever the projector is used, the message “REPL.-LAMP” appears on the
projection screen for about two minutes. When the lamp’s service has reached 1000 hours,
the projector’s LAMP indicator starts blinking, and the projector will not turn on. The
specified lamp replacement period is 1000 hours, but depending on the lamp’s condition,
the replacement period may vary. If video image is dark and its color tint is poor even after
you have adjusted color tint and brightness, replace the lamp a little earlier. Contact your
Madrigal Imaging-authorized dealer where you purchased the projector to have the lamp
replaced.
CAUTION
• Use a genuine product for the Xenon 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 lamp immediately after the projector has been used. The tempera-
ture 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
27), and disconnect the power cord from the wall outlet. If you perform the replace-
ment work with the power cord left connected, this could cause harm or electric shock.
• Never discard a used lamp, as is. Otherwise, this could involve a great danger. The
lamp contains a xenon gas inside, which is under 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 Madrigal Imaging-authorized dealer where you have bought
the replacement lamp.
