4. MAINTENANCE

This section describes the simple maintenance procedures you should
follow to replace the lamp and clean the filter.

Replacing the Lamp

After your lamp has been operating for 2000 hours (up to 3000 hours in
Eco mode) or longer, the “Status” light in the cabinet will go on and the
message will appear. Even though the lamp may still be working, re­place it at 2000 (up to 3000 hours in Eco mode) hours to maintain opti­mal rear projection display performance.

CAUTION

• DO NOT TOUCH THE LAMP immediately after it has been used. It will be

extremely hot. Turn the rear projection display off, wait 30 seconds, and
then turn off the main power. Allow at least one hour for the lamp to
cool before handling.

• DO NOT REMOVE ANY SCREWS except the lamp cover screws and two

lamp housing screws. You could receive an electric shock.

• The projector will turn off and go into stand by mode after 2100 (up to

3150 hours in Eco mode) hours of service. If this happens, be sure to
replace the lamp. If you continue to use the lamp after 2000 hours (up
to 3000 hours in Eco mode) of use, the lamp bulb may shatter, and
pieces of glass may be scattered in the lamp case. Do not touch them as
the pieces of glass may cause injury.
If this happens, contact your NEC dealer for lamp replacement.

For this lamp replacement, use the screwdriver included with the op­tional lamp kit(RT50LP).

1. Remove the lamp cover on the rear cabinet.

Loosen the two lamp cover screws until the screwdriver goes into a
freewheeling condition and remove the lamp cover. The lamp cover
screws are not removable.

2. Remove the lamp cover on the internal projector.

(1) Loosen the single lamp cov er screw until the scre wdriver goes into a
freewheeling condition and (2) remov e the lamp cov er . The screw is not
removable.

3. Remove the lamp housing.

(1) Loosen the two screws securing the lamp housing until the screw­driver goes into a freewheeling condition. The two screws are not re­movable.
(2) Remove the lamp housing by pulling out the handle.

NOTE: There is an interlock on this case to prevent the risk of electrical shock.
Do not attempt to circumvent this interlock.

4. Install the new lamp housing.

(1) Insert a new lamp housing until the lamp housing is plugged into the
socket.
(2) Secure it in place with the two screws.
CAUTION: Do not use a lamp other than the NEC replacement lamp
(RT50LP). Order this from your NEC dealer.

Be sure to tighten the screws.

6. Reattach the lamp cover on the rear cabinet.

Put the lamp cover back on the rear cabinet and tighten the two scre ws.

Be sure to tighten the screws.

7. Clear the lamp usage hours.

After you install a new lamp, select [Advanced Menu] → [Setup] →
[Page 3] → [Clear Lamp Hour Meter] to reset the lamp usage hours.

NOTE: When the lamp exceeds 2100 hours (up to 3150 hours in Eco mode) of
service, the rear projection display cannot turn on and the menu is not dis­played. If this happens, press the Help button on the remote control for a mini­mum of 10 seconds while in standby mode. When the lamp time clock is reset
to zero, the STATUS indicator goes out.

Cleaning and Replacing the Filters

Clean the filter covers after ev ery 100 hours of operation (more often in
dusty conditions).
If the filters are dirty or clogged, the rear projection display may over­heat.
When you replace the lamp, it is also wise to replace the filters.
The filters come in the same package with the NEC replacement lamp
(RT50LP).

Cleaning the filters

To clean the filters:
Vacuum the filter through the filter cover.

CAUTION

*Turn off the main power before cleaning the filter covers.
* Only clean the outside of the filter cover with a vacuum clearner.
* Do not wash the filter cover and filter(sponge) with soap and water.

Soap and water will damage the filter cover and filter membrane.

Replacing the Filters

CAUTION

*Turn off the main power before replacing the filters.
* Before replacing the filters, remove dust and dirt from the cabinet. Keep

out dust and during filter replacement.

*

Do not attempt to operate the rear projection display without the filter covers.

* The rear projection display will not operate unless the filter covers are

installed correctly.

There are two filter covers on the rear projection display; one on the left
side and the other on the right side.
These two filter covers are different in shape.
The coars-mesh sponge is for the right side filter cover and the fine­mesh sponge for the left side filter cover.
Replacement procedures for both sides are the same.

To replace the filter:

1. Loosen the two screws until the screwdriver goes into a

freewheeling condition.

Push up and remove the filter cover.

2. Remove the filter and replace it with the new one.

1)Gently remove the old filter from the filter cover.

2)Gently peel off a double-faced tape on the new filter. Be careful not to
tear off the filter.

3)Place the new filter on the filter cover with the adhesive side down.

3 Reinstall the filter.

1)Place the filter cover into the cabinet, aligning the hook to engage.

2)Tighten the two screws.

• Check that the power cable is plugged in, the main power switch is on, and that the power button on the
cabinet or the remote control is on.

• Ensure that the lamp cover is installed correctly. See page E-36.

• Check to see if the rear projection display has overheated or the lamp usage exceeds 2100 hours (3150
hours in Eco mode). If there is insufficient ventilation around the rear projection display or if the room where
you’re presenting is particularly warm, move the rear projection display to a cooler location.

• Use the menu to select your source (Video, S-Video or RGB). See page E-31.

• Ensure your cables are connected properly.

• Use menus to adjust the brightness and contrast. See page E-31.

• Reset the settings or adjustments to factory preset levels using the Factory Default on the Image Options
Menu in Advanced mode. See page E-33.

• Use menus or Source button on the remote control or the cabinet to select the source you want to input.

• Install new batterys. See page E-14.

• Make sure there are no obstacles between you and the rear projection display.

• Stand within 22 feet (7 m) of the rear projection display. See page E-14.

•

Make sure that you are in the rear projection display mode and the PJ button lights in red. If not, press the PJ button.

• Make sure the remote control cable plug is not inserted into the REMOTE CONTROL input mini jack on the
rear terminal panel.

• See the Power/ Status Light messages above.

• If Auto Adjust is off, turn it on. If Auto Adjust is on, turn it off and balance the image with the P osition and Clock
Adjust on the Advanced Options Menu. See page E-33.
