Solving Problems with the Image or 
Sound
No image appears on the screen.
■Check that the power light is green, not flashing, and the lens cap 
is off. 
■The projector may be in standby or sleep mode. If the projector 
has not received any input signal for 30 minutes, it turns off the 
lamp to conserve the lamp life and save energy. If the power light 
is orange, press the  P 
Power button to turn the projector on.
■Press the A/V Mute button to make sure the picture has not been 
turned off temporarily. 
■If the power was switched off and then on again, wait until the 
power light stops flashing and remains orange; then press the  P 
Power button again.
■Check the Video Signal or Computer1 Input or Computer2 
Input 
setting in the Signal menu to make sure it is correct for the 
selected source. See page 58 for more information.
■Have messages been turned off in the Display setting of the 
Extended menu? See page 62 for details.
■Adjust the Brightness setting on the Image menu or select High 
for the 
Brightness Control setting in the Extended menu. See 
page 56 or page 61.
■The attached computer may be in sleep mode or displaying a 
black screen saver. Try pre ssing a key on the computer. 
						

							
86Solving Problems
Nothing appears on the external monitor.
■Make sure the VGA computer cable is connected to your 
computer’s video port and the projector’s 
Computer1(Component) port. It will not work if you 
connected the computer cable to the projector’s 
Computer2(Component) port.
■Make sure the cable from your monitor is connected to the 
projector’s 
Monitor Out port.
You see a blue screen with the message No Signal displayed.
■Make sure the cables are connected correctly, as described in 
Chapter 1.
■Make sure the power to your computer or video source is 
turned on.
■If you’ve connected a computer and one or more video sources, 
you may need to press the 
Source Search button on the 
projector or the 
Comp1, Comp2, S-Video, or Video button on 
the remote control to select the correct source. Allow a few 
seconds for the projector to sync up after pressing the button.
■If you’ve connected a laptop computer, make sure it’s set to 
display on an external monitor. See page 35. 
If you’re using a PC laptop:
■Hold down the Fn key and press the function key that lets you 
display on an external monitor. It may have an icon such as 
, or it may be labelled 
CRT/LCD. Allow a few seconds for 
the projector to sync up after pr essing it. Check your laptop’s 
manual or online help for details. 
On most systems, the   or 
CRT/LCD key lets you toggle 
between the LCD screen and the projector, or display on both at 
the same time.  
						

							
Solving Problems87
■Depending on your computer’s video card, you might need to use 
the Display utility in the Control Panel to make sure that both the 
LCD screen and external monito r port are enabled. See your 
computer’s documentation or online help for details.
If you’re using a PowerBook or iBook with 
Macintosh OS X:
1. From the Apple menu, select System Preferences, then click 
Display or Displays.
2. Select 
VGA Display or Color LCD, click Arrange or 
Arrangement, then put a check mark in Mirror Displays.
If you’re using a PowerBook or iBook with
Macintosh OS 9:
1. From the Apple menu, select Control Panels, then click 
Monitors or Monitors and Sound.
2. Click the Arrange icon.
3. Drag one monitor icon on top of  the other. This lets you display 
on the projector screen as  well as the LCD screen.
4. If the 
Arrange icon isn’t available, click the Monitor icon. 
5. Select one of the listed 
Simulscan resolutions. (Allow a few 
seconds for the projector to sync up after making the selection.)
The message Not Supported is displayed.

the PowerLite 82c) or SVGA (for the PowerLite 62c) and the 
frequency is supported by the projector. See page 100. If 
necessary, change your computer’s  resolution setting as described 
below. 
■Make sure the correct Video Signal is selected in the Signal

■If you’ve enlarged part of the image using the E-Zoombutton 
on the remote control, press the 
Esc button to cancel zooming 
and return to full display.
■Try pressing the Resize button on the remote control to select a 
different aspect ratio (ratio of length to height).
■Make sure your computer’s resolution setting is correct. Ideally, 
it should be 1024 × 768 (for the PowerLite 82c) or 800 × 600 
(for the PowerLite 62c) to match the projector’s native resolution. 
If this option isn’t available, se lect one of the other compatible

■You also may need to modify existing presentation files if you 
created them for a different re solution. See your software 
documentation for specific information. 
						

							
Solving Problems89
The image isn’t rectangular, but trapezoid-shaped.
■Make sure the projector isn’t placed off to one side of the screen, 
at an angle, or the image won’t be rectangular. Place it directly in 
front of the center of the scre en, facing the screen squarely.
■If you’ve tilted the projector upward, the image will be broader at 
the top. Turn on Auto Keystone correction as described on 
page 60 or hold down the   or   buttons on top of the 
projector until the image is rectangular.
The image contains static or noise.
■If you’re using a computer cable longer than 6 feet, or an 
extension cable, the image quality may be reduced.
■Keep your computer and video ca bles separated from the power 
cord as much as possible to prevent interference. 
						

							
90Solving Problems
■The video signal may be split between the computer and the 
projector. If you notice a decline in the projected image quality 
when the image is displayed simultaneously on your laptop 
computer and the projector, turn off the laptop’s LCD display.
■If you’re projecting from a co mposite or S-Video source, check 
the 
Video Signal setting in the Signal menu. In most cases, leave 
it set at 
Auto. If you’re using a 60-Hz PAL video source, change 
this setting to 
PAL60. See page 60 for details.
■Make sure the cables are securely connected at both ends.
■Select the correct resolution; se e “Compatible Video Formats” on 
page 100.
■If you’re projecting from a computer, press the Auto button on 
the remote control or the 
Enter button on the projector to adjust 
tracking and sync automatically. If that doesn’t work, try 
adjusting the 
Sync and Tracking settings in the Signal menu. See 
page 59.
The image is blurry.
■Adjust the focus using the focus ring.
■Make sure the lens cap is off.
■There may be dirt or smears on the lens. Clean the lens as 
described on page 74.
■Make sure the lens is not fogged by condensation. You may need 
to wait before using the projector after moving it from a cold 
environment.
■Make sure the projection distance is within the range described on 
page 16.
■Adjust the Sharpness setting on the Image menu (see page 57). 
You should be able to see the effect on the screen immediately.
