• 

The warning lights on the projector indicate problems inside the projector.

• 

There are three warning lights: a TEMPERATURE WARNING indicator that warns you
when the projector is too hot, and two LAMP REPLACEMENT indicators that warn you
when to change a lamp.

• 

If a problem occurs, either the temperature warning indicator or the lamp replacement
indicator will illuminate red, and the power will turn off. After the power has been turned
off, follow the procedures given below.

If the temperature inside the projector increases, due
to blockage of the air vents, or the setting location,
“TEMP ” will blink 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 further 90
seconds, then the power will be shut off. After
“TEMP” appears, be sure to perform the following
measures.

• 

When the remaining lamp life becomes 900
hours or more, “Lamp Warning Icon” will be
displayed on the screen in yellow. When the
hours reach 1000,  “Lamp Warning Icon” will
change to “Lamp Warning Icon” (red), the lamp
will automatically turn off and then the projector
as well. At this time, the lamp replacement
indicator will illuminate in red.

• 

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

If the temperature warning indicator illuminates, and the power turns off, follow the above possible
solutions 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 and then turned on again, as during a brief test, the lamp replacement
indicator may be triggered, preventing the power from going on. Should this occur, take the power
cord out of the wall outlet and plug it back in again.

• 

It is recommended that the lamp (sold separately) be replaced when the remaining lamp life
becomes 900 hours or greater, or when you notice a significant deterioration in the picture and
colour quality. The lamp life can be checked with the on-screen display. 

• 

For lamp replacement, please consult your nearest Sharp Authorised Projector Dealer or Service
Centre.

• 

This projector utilises a pressurised 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 or flash, 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 cage 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 with 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 Authorised Projector
Dealer or Service Centre to remove the damaged lamp and assure safe operation.

• 

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
Authorised Projector Dealer or Service Centre for repair. Purchase a replacement lamp
unit of type BQC-XGV10WU/1 from your nearest Sharp Authorised Projector Dealer or
Service Centre. 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
Authorised Projector Dealer or Service Centre.
