 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 28.)
 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 27.)
 Replace the lamp. (See page 35.)
Projected images are blurred. Adjust the focus. (See page 16.)
 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 28.)
 Adjust BRIGHTNESS and CONTRAST in the QUICK MENU or the IMAGE menu. (See page 27.)
 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 25.)
 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 43.)
 Some images and texts appear obscured during the keystone adjustment. In such cases, use the projector 
without applying the keystone adjustment. (See page 15.)
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.
Projector images are twitching. Projector may be vibrating. Set AUTO KEYSTONE to OFF or lower the VOLUME T button of the Remote 
control.

Troubleshooting (continued)
Others
If the following problem occurs after the lamp is replaced, check the following first.
Maintenance 
Warning:Do not use flammable solvents (benzene, thinner, etc.) and flammable aerosols when cleaning the projector body and lens. Flammable substances 
may ignite causing fire or breakdown while the lamp is illuminating.
Caution: Be sure to turn off the lamp and unplug the power cord from the wall outlet before you perform any maintenance on the projector. 
Cleaning of the projector and the ventilation slots Use a soft cloth to clean the projector and the ventilation grilles. When the grilles become dirty, wipe them with a soft cloth dampened with diluted 
mild detergent, and then wipe them with a dry cloth. 
To protect the surface of the projector from fading or deteriorating:  Do not spray insecticide on or inside the projector. 
 Do not use benzin or thinner to clean it. 
 Do not let rubber or plastic materials contact with projector. 
Cleaning of the lens Use a standard lens-cleaning brush or a piece of lens tissue dampened with lens cleaning fluid. The lens surface is fragile. Use only recommended, 
nonabrasive lens-cleaning materials. Do not touch the lens with your fingers. 
 
ProblemSolution
The exhaust vents emit warm air.  This air comes out after cooling the inside of the projector. You may feel hot, but this is not a malfunction.
No audio is output. Check that the volume isn’t set to low.
 Check the AUDIO INPUT setting.
 When the external device is connected with an HDMI cable, set the audio output of the device to PCM output.
The menu can’t be used. The microcomputers inside the projector may be wrongly operating because of noise.
JPress the POWER button to turn off the lamp and unplug the power cord from the wall outlet. Wait about 
10 minutes, plug the power cord in, and try again.
