Troubleshooting
Problem: Nothing on projection screen
•
Make sure that the power cord is properly conn ected to a func-
tional AC electrical outlet. Make sure that the power cord is
also properly connected to the projector.
•
If the projector is plugged into a power strip, make sure the
power strip is turned on.
•
Make sure you have removed the lens cap on the projection
lens at the front of the projector.
•
Make sure the projector is switched on.
•
Check the projector’s lamp to ensure that it is securely con-
nected in the lamp module. See “Replacing the Projection
Lamp” on page 25.
•
Make sure that the cables do not have any bent pins.
Problem: Color or text not being projected
•
You m ight need to adjust the brightness up or down until the
text is visible. Refer to “Brightness” on page 17 for more information.
Problem: The screen resolution is not right
•
Make sure the computer’s video card is set for a resolution of
no greater than 1024x768. A resolution of 800x600 yields the
highest quality image.
Problem: Image isn’t centered on the screen
•
Reposition the image. Refer to “Horiz. Position” on page 21
and “Vert. Position” on page 21.
•
Be sure the projector is at a 90 degree angle to the screen.
Problem: Only the start-up screen displays
•
Verify that the cables are connected correctly. See page 7
through page 9 for connection procedures.
•
Verify that the proper input source is connected. See “Source”
on page 15.
29
Maintenance & Troubleshooting
•
You might need to turn everything off and power up the
equipment again in the proper order. Refer to your computer’s documentation to determine the correct order.
•
Make sure your laptop’s external video port is turned on. See
the “Portable and Laptop Activation Chart” on page 37 or
your computer’s manual for details.
•
Make sure your computer’s video board is installed and con-
figured correctly.
If you’re using Windows 3.x:
In the Windows Program Manager, double-click the Win-
1
dows Setup icon in the Main program group.
Verify that the Display setting is 1024x768 or less.
2
If you’re using Windows 95:
Open “My Computer” icon, the Control Panel folder and
1
then the Display icon.
Click the Settings tab.
2
Verify that the Desktop area is set to 1024x768 or less.
3
Also check the following:
•
Does your computer have a compatible video board? The pro-
jector isn’t CGA or EGA compatible.
•
Is your computer’s video port activated? This is especially
true for laptop computers. See “Portable and Laptop Activation Chart” on page 37.
Problem: Image is too wide or narrow for screen
•
You might need to manually adjust the tracking to reduce or
enlarge the projected image. Refer to “Manual Tracking” on
page 21.
•
Adjust the resolution of your video card if it’s greater than
1024x768 pixels.
30
Problem: Image is out of focus
•
Turn the projection lens to focus the image.
•
Make sure the projection screen is at least 5 feet (1.5 m) from
the projector.
•
Check the projection lens to see if it needs cleaning.
Problem: Image and menus are reversed left to right
•
Rear projection mode is probably turned on. Turn Rear Projec-
tion off in the Controls menu. The image should immediately
return to forward projection. See “Rear Projection” on
page 23.
Problem: the projector displays vertical lines, “bleeding” or
spots
•
Adjust the brightness. See “Brightness” on page 17.
•
Check the projection lens to see if it needs cleaning.
Problem: no sound
•
Adjust volume.
•
Verify audio/input connections.
•
Adjust audio source.
Problem: Image is “noisy” or streaked
Try these steps in this order.
Deactivate the screen saver on your computer.
1
2
Turn
Auto Image
off and then back on again. See “Auto
Image” on page 20.
Adjust the synchronization and trac king manually to find an
3
optimal setting. See “Manual Sync” on page 21 and “Manual
Tracking” on page 21.
•
The problem could be with your computer’s video card. If
possible, connect a different computer.
31
Maintenance & Troubleshooting
Problem: Pro jected colors don’ t match the com puter or vid eo
player’s colors
•
Adjust the brightness, tint and/o r contrast from the Display
menu. Just as there are differences in the displays of different
monitors, there are often differences between the computer
image and the projected image. See “Brightness” on page 17,
“Tint” on page 17 and “Contrast” on page 17.
Problem: Lamp seems to be getting dimmer
•
The lamp begins to lose brightness when it has been in use for
a long time. Replace the lamp as described in “Replacing the
Projection Lamp” on page 25.
Problem: Lamp shuts off
•
A minor power surge may cause the lamp to shut off. Turn the
projector off, wait at least a minute, then turn it back on.
Before calling your dealer or In Focus Technical Support for assistance, please have the following information available:
32
•
the projector’s serial number (located on the bottom label)
•
the resolution of your computer.
Call In Focus Technical Support at
1-800-799-9911

Using Video Mirroring with a PowerBook Computer
When you turn video mirroring (called SimulScan in newer PowerBooks-see below) on, the projector displays the same information that appears on your PowerBook’s built-in screen. When
video mirroring is off, the projector acts like a separate display.
To turn on video mirroring for the first time:
Open the Monitors control panel; click on Monitor 2.
1
Set the number of colors you want.
2
Open the Control Strip; click on the monitor icon.
3
Select “Turn Video Mirroring On.”
4
Now you can turn video mirroring on and off from the Control
Strip without having to open the Monitors control panel again.
When using video mirroring and high color graphics such as
slide shows, the projected image occasionally might turn black
and white. If this happens, perform the following steps:
Turn off video mirroring.
1
Open the Monitors control panel.
2
Move the white menu bar to Monitor 2 to set the projector as
3
the primary monitor.
Restart the PowerBook.
4
Using SimulScan
Some newer PowerBooks display images on an external monitor
or projector differently than previous ones. When using
SimulScan, the projector displays the same information that
appears on your PowerBook
To select Sim ulScan:
Open the Control Panel, then double-click Monitors and
1
Sound.
In the Resolution list, choose the SimulScan mode, then click
2
OK.
If this changes your display settings, a dialog box appears.
3
Click OK to confirm the change.
