Lamp replacement
This projector is equipped with a lamp to project images. This lamp is 
a consumable. It may burn out or its brightness may decrease during 
use. In such cases, replace the lamp with a new one as soon as possi-
ble. Be sure to replace the lamp with a new lamp separately sold that 
is exclusive to this projector. Contact your dealer for purchase of the 
lamp.
Replace the spare lamp using the lamp attachment unit that is 
equipped with the spare lamp (separately sold) designed specifically 
for this projector.
Caution: Do not remove the lamp immediately after using the projector. You 
may get burned because the lamp is very hot after use.
 Before replacing the lamp, press the POWER button to turn off the 
lamp and wait for two minutes for lamp to cool down. Unplug the 
power cord from wall outlet and wait one hour for the lamp to cool 
down completely.
 Do not remove the lamp except for replacement. Careless han-
dling can cause injury or fire.
 Do not touch the lamp directly. It may break and cause injury or 
bur n.
 Be sure not to drop the lamp lid screw into the projector. Also be 
sure not to put metal or any flammable objects inside because it 
may cause fire or electric shock. If any objects should fall inside, 
unplug and contact your dealer.
 Install the lamp securely to prevent failure and fire.
 If the lamp should break, small glass fragments may fall out 
through the grilles and some may remain inside of the projector or 
the lamp box. When taking the lamp box out, be sure to turn over 
the projector and hold the handle of the lamp box to avoid injury 
due to the glass fragments.
 If the lamp should break, never shake the lamp box or hold it in 
front of your face after removing it. The glass fragments may fall 
out and cause injury to your eyes.
 Be sure to use the lamp dedicated to this projector, VLT-XD221LP 
for XD221U-ST. Use of other lamps may cause a failure of the pro-
jector.
 Do not use any other tools for replacing the spare lamp, and be 
sure to use the lamp attachment unit that is equipped with the 
spare lamp (separately sold) designed specifically for this projec-
tor. Use of other tools may cause a failure of the projector.
Make sure that the projector is securely held in place.
1. Remove the cover (a) of the screw fixing the lamp cover with a fin-
gernail. If it is difficult to remove it with a fingernail, use a fine-
tipped tool such as flathead screwdriver.
2. Remove the screw (b) and slide the lamp cover (c) for removal.The lamp unit is fixed in position with two retaining claws (d) inside 
so the lamp attachment unit (e) designed specifically for this pro-
jector is required to replace the lamp.
Do not pull out the lamp forcibly. The lamp unit may be irretrievably 
damaged.
A new lamp unit can be installed without the lamp attachment unit.
3. Loosen the two screws (g) indicated as arrows (
J) in figure, and 
mount the lamp attachment unit (e).
Slide the lamp attachment unit in the direction indicated by a white 
arrow after the installation of it, and hook the claw (f) into the hole 
of the device to fix the lamp attachment unit.
If not hooking the claw, the lamp attachment unit will be lifted with-
out being fixed in the precise position.
(Caution)
When replacing the lamp, do not remove the screws other than 
those in the above picture. If do, it might cause the failure of prod-
uct.
When the projector is mounted to the ceiling:
Secure the lamp attachment unit and the projector with the screw 
(h) that come with the lamp attachment unit. Otherwise, the lamp 
unit may fall from the inside and cause injuries.

Caution: The lamp is fragile. If it is broken, be careful not to cut yourself with 
glass fragments.
 Contact your dealer for a new lamp.
Interval of lamp replacementWhen the lamp lifetime notice is issued, the lamp replacement is rec-
ommended even if the lamp is lit normally. Decrease in luminescence 
and/or color brightness indicates that the lamp needs to be replaced. 
When the lamp operation time exceeds the time elapsed until the 
lamp lifetime notice
*1 is issued, the indicator will blink alternately 
green and red while the lamp is lit (while the lamp is not lit, the indica-
tor will blink red only) and the lamp replacement message will appear 
on the screen for one minute every time the lamp is turned on. When 
the lamp operation time exceeds the time elapsed until the lamp life-
time warning
*2 is issued, the replacement message (LAMP 
EXCHANGE) will appear on the screen for one minute at fixed inter-
vals
*4 thereafter.
When the lamp operation time exceeds the time elapsed 
until the lamp lifetime*3, the projector keeps on issuing 
the warning, shuts off automatically after ten minutes, 
and then enters the standby state.
The times above are when LAMP MODE of the INSTALLATION menu 
is set to LOW. When it is set to STANDARD, this duration will be short-
ened.
*4These intervals vary depending on the lamp mode setting.*5When LAMP MODE is set to STANDARD, the time elapsed until 
the lamp lifetime will be shortened to 3000 hours.

 When images are displayed correctly, add an RGB signal amplifier to the extension cable.
Pow e r  t u r n s  o f f. This problem may occur when the intake vent and/or exhaust vents are blocked. (In such a case, the STATUS 
indicator brinks orange.)
JRemove the objects blocking the intake vent and/or exhaust vents and then carry out the following proce-
dure.
1. Wait for the intake fan and/or exhaust fan to stop. (Wait until the STATUS indicator goes out.)
2. Unplug the power cord from the wall outlet.
3. Wait about 10 minutes.
4. Plug the power cord into the wall outlet.
5. Press the POWER button.
 Check that AUTO POWER OFF has been set to OFF.
 If the lamp has deteriorated, it may go out after a while it illuminates.
The screen for entering the password appears. PASSWORD FUNCTION in the FEATURE menu has been set to DISPLAY INPUT to enable the password

JEnter the password or contact the person in charge of management of the projector.
(See page 25.)
NO SIGNAL is displayed. Turn on the power of the connected device, or check whether there is something wrong with the connected 
device.
 Check whether the external device output signals. (Check this especially when the external device is a note-
book computer.)
 Check that the cable connected to the external device isn’t defective.
 Check that the projector is connected to the external device using the correct terminals.
 Check that the connected device is correctly selected as the input source.
 When an extension cord is being used, replace it with the supplied cable and check whether images are pro-
jected correctly. If images are projected correctly, use an RGB signal amplifier along with the extension cord.

POWER STATUS Solution
 Connect the power cord to the projector. Plug the power cord into a wall outlet. If any objects are blocking the air inlet or outlet grille, remove them and carry out 
the following.
1.  Unplug the power cord from the wall outlet.
2.  Make sure that the projector has cooled off.
3.  Plug the power cord into the wall outlet.
4.  Press the POWER button.
 If any objects are blocking the air inlet or outlet grille, remove them. Dont expose the air outlet grilles to hot air emitted from a heating appliance.
 After the STATUS indicator stops blinking, press the POWER button. If you unplug the power cord while the fan is rotating, the lamp may not turn on about 1 
minute when you plug the power cord next time.
 The lamp cant turn on again for 1 minute after it goes out. Press the POWER button several times. Attach the lamp cover on the top.
 Unplug the power cord from the wall outlet and contact your dealer.

Troubleshooting (continued)
Images are not displayed correctly.
ProblemSolution
Projected images are shaking.
Projected images are displaced. Check that the cable connected to the external device isn’t intermittent.
 Connect the cable’s plug with the external device’s connector firmly.
 Press the AUTO POSITION button.
 Some computers output out-of-spec signals on rare occasion. Adjust the SIGNAL menu. (See page 24.)
 When the input signal is a WXGA video signal, confirm the setting selected in WXGA in the FEATURE menu.
 When the input signal is other than a WXGA video signal, select OFF in WXGA in the FEATURE menu.
Projected images are distorted.  Adjust the projector and the screen so that they are perpendicular to each other. (See page 9.)
Projected images are dark. Adjust BRIGHTNESS and CONTRAST in the QUICK MENU or the IMAGE menu. (See page 23.)
 Replace the lamp. (See page 27.)
Projected images are blurred. Adjust the focus. (See page 13.)
 Clean the lens.
 Press the W or X button on the remote control to eliminate flicker.
 Adjust TRACKING and FINE SYNC. in the SIGNAL menu. (See page 24.)
 Adjust BRIGHTNESS and CONTRAST in the QUICK MENU or the IMAGE menu. (See page 23.)
 Adjust the projector and the screen so that they are perpendicular to each other. (See page 9.)
Afterimages persist on the screen. This phenomenon is improved by keeping projecting an evenly bright image. (Such image burn-in phenom-
enon where afterimages persist on the screen may occur if a stationary image is kept displayed on the screen 
for a long time.)
White dots are seen on projected images. Black dots 
are seen on projected images. This phenomenon is normal for a DLP projector and is not a malfunction. (A very small number of pixels may 
visibly or invisibly be persistent all the time, but they are not a sign of system malfunctions. Over 99.99% of 
the pixels are effective.)
Fine streaks are seen on projected images. This is due to interference with the screen surface and is not a malfunction. Replace the screen or displace 
the focus a little.
 Vertical or horizontal streak noise may appear on the projected image, depending on the type of the DVD 
player, game console or computer you use. In such a case, you can reduce such streak noise by enabling the 
LPF.
Projected images become wavy. Connect the plugs of the cables to external devices securely. 
 Keep the projector away from equipment generating interfering radio waves. 
 When the keystone adjustment is carried out, the image may not be displayed correctly because of the type 
of input signal. This isn’t a product malfunction. In this case, readjust the keystone so that the amount of key-
stone correction is as small as possible. 
Hue is not appropriate.  Check that the cables connected to the external devices are not broken.
Tint in projected images is incorrect. Check that COMPUTER INPUT in the SIGNAL menu is correctly set. (See page 22.)
 Check that the cable connected to the external device isn’t broken.
Different color tint. When comparing images projected by two projectors, tints in the displayed images may be different because 
of variation between their optical components. This is not a malfunction.
 When comparing the image projected by this projector with those displayed on the television or PC monitor, 
tints in the displayed images may be different because of difference in the range of color reproducibility. This 
is not a malfunction.
Only the motion areas in the images supplied from 
the computer aren’t displayed. This is caused by the computer being used. Contact the manufacturer of your computer.
Projected images are obscured. Match the output resolution of your computer with the resolution of the projector. For the method to change 
the output resolution of the computer, contact the manufacturer of your computer. (See page 35.)
 Some images and texts appear obscured during the keystone adjustment. In such cases, use the projector 
without applying the keystone adjustment. (See page 12.)
Projected images are flickering After the Power button or On button on the remote has been pressed, or the Lamp mode setting has 
changed, images may be flickering until the lamp lights stably. This is an expected behavior.
 When selecting the input signal, Auto Position, and Color Enhancer, the projected image may be flickering 
temporarily. This is not a product malfunction.
