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 consumable part. It may go off or its brightness may decrease during use. In these cases, replace the lamp to new one in good time. For the replacement, be sure to use the light-source lamp that is sold exclusively for TDP-MT500. 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 plug. 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 containing foreign matters, electric shock or fire may be caused. If users can not take out the foreign matters inside, ask a repair front of Mitsubishi Electric Corporation 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 over 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 burn. 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.

Caution

In this projector, a LAMP indicator blinks after the light-source lamp has been used 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 failure.

As the light-source lamp, the high-pressure mercury lamp is used. 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. Also, it may stop lighting when it comes to its life end. 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 its start of use.

The possibility of burst of the high-pressure mercury lamp increases if it is used beyond its replacement period. When the indication of lamp replacement appears, immediately replace the lamp to new one 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 should be 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 a service outlet of Mitsubishi Electric Corporation to replace the light-source lamp and check the interior of the projector. When users make the cleaning and the replacement of the lamp for them- selves, be sure to turn the main unit upside down and do it holding the lamp holder. Otherwise, the broken glass pieces of the lamp may cause injuries.
