REPLACING THE LAMP/CLEANING THE PROJECTOR
The light-source lamp is stored in the projector to project picture images on screen. The light-source lamp is a consum-
able part. It may go off or its brightness may decrease during use, this is a characteristic of the lamp and is not a
malfunction. In these cases, replace the lamp to new one in good time. To replace the lamp, be sure to use the light-
source lamp that is sold exclusively for the TDP-MT500 (Model TDPLMT50). For the details, refer to the operation
manual for TLPLMT50. Purchase the lamp from the delivery agent of the projector.
Warning
•
Before replacing the light-source lamp, be sure to turn off the main power switch and unplug the power
cord. Replacing the lamp without turning off the main power switch can cause electric shock.
•
When replacing the light-source lamp, be cautious not to drop the screws fixing the lamp into the inside of the
projector. Do not put any metal pieces or easily flammable things in the projector. If the projector is
operated with foreign material inside, electric shock or fire may be caused. If users can not take out the
foreign matters inside, ask your dealer to take them out.
•
Securely fix the light-source lamp. If it is not fixed properly, it will not come on and may cause fire.
•
Never shake the replaced light-source lamp or bring it near your face. The lamp may be broken and its
broken glass pieces may be scattered or enter human eyes causing injuries.
•
Do not replace the light-source lamp immediately after its use, because it is very hot and may cause
burns. Turn off the power button to put off the lamp, and wait about 2 minutes until the cooling fan
comes to a complete stop. Then, turn off the main power switch and unplug the power plug. After more
than one hour has passed and the lamp has been thoroughly cooled down, replace the lamp.
•
When this projector is ceiling-mounted, ask your dealer for the maintenance such as cleaning and lamp
replacement.
Caution
In this projector, a LAMP indicator blinks after the light-source lamp has been used for more than 1000 hours.
When the lamp has been used more than 1300 hours, a warning appears on the screen every time the
power is turned on. After more than 1500 hours of use, the power for the lamp is automatically turned off
and the lamp can not be used any more. Then, replace the lamp to new one as soon as possible.
•
Do not remove the light-source lamp except when it is replaced. Otherwise, removing it may cause a malfunction.
•
The light-source lamp is a high-pressure mercury lamp. The high-pressure mercury lamp may burst
with a disruptive sound, if it is shocked or scratched, or if the lamp deteriorates while being used. The
lapse of time until each lamp bursts or stops lighting, if it occurs, depends on the characteristics or use
condition of each lamp. Therefore, there is a possibility that it may burst by chance even in a short time
after you start using it.
•
The possibility of bursting of the high-pressure mercury lamp increases if it is used beyond its replace-
ment period. When the indication of lamp replacement appears, immediately replace the lamp to a new
one even if the lamp is lighting normally.
•
If the high-pressure mercury lamp bursts, the fragments of the glass valve may scatter in and out of the lamp
box, or the gas filled in the valve may come out of the ventilation outlet. The gas filled in the high-pressure
mercury lamp contains mercury vapor. Be extremely cautious not to inhale the gas or bring the gas into eyes or
mouths. If the gas is inhaled or brought into eyes or mouths, consult a doctor immediately.
•
If the high-pressure mercury lamp bursts, fragments of the glass valve are scattered inside of the projector. It is
recommended to ask your dealer to replace the light-source lamp and check the interior of the projector. When
users clean and replace the lamp for themselves, be sure to turn the main unit upside down and do it
holding the lamp holder. Otherwise, the broken pieces of the lamp may cause injuries.
