About the temperature warning indicator
If the temperature inside the
projector increases, due to
blockage of the air vents, or the
setting location, “
” will
illuminate in the lower left corner of the picture. If
the temperature keeps on rising, the lamp will turn off
and the temperature warning indicator will blink, the
cooling fan will run for a further 90 seconds, and then
the projector will enter the standby mode. After
“
” appears, be sure to perform the following
measures.
About the lamp indicator

The lamp life becomes 0%, when used
for approximately 4,000 hours with “Eco
mode” or when used for approximately
3,000 hours with “Standard mode” (see
page 53).

When the remaining lamp life becomes
5% or less, “
” (yellow) will be displayed
on the screen. When the percentage be-
comes 0%, “
” will change to “” (red),
the lamp will automatically turn off and
then the projector will automatically en-
ter the standby mode. At this time, the
lamp indicator will illuminate in red.

If you try to turn on the projector a fourth
time without replacing the lamp, the pro-
jector will not turn on.

Regarding the Lamp
Info
•If the temperature warning indicator illuminates, and the projector enters the standby mode, follow the pos-
sible solutions on the previous page and then wait until the projector has cooled down completely before
plugging in the power cord and turning the power back on. (At least 5 minutes.)
•If the power is turned off for a brief moment due to power outage or some other cause while using the
projector, and the power supply recovers immediately after that, the lamp indicator will illuminate in red and
the lamp may not be lit. In this case, unplug the power cord from the AC outlet, replace the power cord in the
AC outlet and then turn the power on again.
•If you want to clean the air vents during projector operation, be sure to put the projector into the standby
mode. After the cooling fan has stopped, clean the vents.
•The cooling fan keeps the internal temperatures of the projector constant and this function is controlled
automatically. The sound of the cooling fan may change during operation because the fan speed may change
and this is not a malfunction.
•Do not unplug the power cord after the projector has entered the standby mode and while the cooling fan is
running. The cooling fan runs for about 90 seconds.
Lamp

It is recommended that the lamp (sold separately) be replaced when the remaining lamp life be-
comes 5% or less, or when you notice a significant deterioration in the picture and color quality.
The lamp life (percentage) can be checked with the on-screen display. See page 51.

For lamp replacement, please consult your nearest Sharp Authorized Service Center or Dealer.
IMPORTANT NOTE TO U.S. CUSTOMERS:
The lamp included with this projector is backed by a 90-day parts and labor limited warranty. All service
of this projector under warranty, including lamp replacement, must be obtained through a Sharp Autho-
rized Service Center or Dealer. For the name of the nearest Sharp Authorized Service Center or Dealer,
please call toll-free: 1-800-BE-SHARP (1-800-237-4277).
U.S.A. ONLY
Caution Concerning the Lamp

This projector utilizes a pressurized mercury lamp. A loud sound may indicate lamp failure. Lamp
failure can be attributed to numerous sources such as: excessive shock, improper cooling, surface
scratches or deterioration of the lamp due to a lapse of usage time. The period of time up to failure
largely varies depending on the individual lamp and/or the condition and the frequency of use. It is
important to note that failure can often result in the bulb cracking.

When the lamp replacement indicator and on-screen display icon are illuminated, it is recommended
that the lamp be replaced with a new one immediately, even if the lamp appears to be operating
normally.

Should the lamp break, the glass particles may spread inside the lamp unit or gas contained in the
lamp may be vented into the room from the exhaust vent. Because the gas in this lamp includes
mercury, ventilate the room well if the lamp breaks and avoid all exposure to the released gas. In
case of exposure to the gas, consult a doctor as soon as possible.

Should the lamp break, there is also a possibility that glass particles may spread inside of the
projector. In such a case, it is recommended you contact your nearest Sharp Authorized Service
Center or Dealer to remove the damaged lamp and assure safe operation.
Replacing the Lamp
Caution
•Do not remove the lamp unit immediately after operation of the projector. The lamp will be hot and touching
it can lead to burn or injury.
•Wait at least one hour after the power cord is disconnected to allow the surface of the lamp unit to fully cool
before removing the lamp unit.

If the new lamp does not light after replacement, take your projector to the nearest Sharp Autho-
rized Service Center or Dealer for repair. Purchase a replacement lamp unit of type BQC-XVZ200++1
from your nearest Sharp Authorized Service Center or Dealer. Then carefully change the lamp by
following the instructions described in this section. If you wish, you may have the lamp replaced at
your nearest Sharp Authorized Service Center or Dealer.
