• Check to see if the projector has overheated. If there is insufficient v\
entilation around the projector or if the
room where you are presenting is particularly warm, move the projector t\
o a cooler location.
• Check to see if the lamp usage exceeds 2100* hours (up to 3100* hours :\
 Eco mode). If so, replace the lamp.
After replacing the lamp, reset the lamp hours used. ( → page  48)
* VT58 and VT48: 3100 hours (up to 4100 hours in Eco mode)
• The lamp may fail to light. Wait a full minute and then turn on the power again.
• Ensure that the Power Management or Off Timer is off. ( → page  45)
• Use the VIDEO, the S-VIDEO or the COMPUTER button on the remote control \
to select your source (Computer,
Video or S-Video). ( → page  21) If there is still no picture, press the button again.
• Ensure your cables are connected properly.
• Use menus to adjust the brightness and contrast. ( → page  41)
• Remove the lens cap.
• Reset the settings or adjustments to factory preset levels using the [Reset] in the Menu. ( → page  48)
• Enter your registered keyword if the Security function is enabled. ( → page  30)
• Be sure to connect the projector and notebook PC while the projector is \
in standby mode and before turning on
the power to the notebook PC.
In most cases the output signal from the notebook PC is not turned on un\
less connected to the projector
before being powered up.
* If the screen goes blank while using your remote control, it may be the \
result of the computers screen-
saver or power management software.
• See also the next page.
• When one of the following happens, the Lamp mode automatically changes f\
rom Normal to Eco.
* When there are no signals  → To return to the Normal mode, select another available source.
* When the room where you re presenting is particularly warm  → Move the projector to a cooler location.

. ( → page  24)
• Adjust the focus. ( → page  23)
• Reposition the projector to improve its angle to the screen. ( → page  22)
• Ensure that the distance between the projector and screen is within the \
adjustment range of the lens.
(→  pages  9 for VT580/VT480/VT58 and  10 for VT48)
• Condensation may form on the lens if the projector is cold, brought into\
 a warm place and is then turned on.
Should this happen, let the projector stand until there is no condensati\
on on the lens.
• Use the VIDEO, the S-VIDEO or the COMPUTER button on the remote control to select your source (Video, S-

7. Appendix
If there is no picture, or the picture is not displayed correctly.
• Power on process for the projector and the PC.
Be sure to connect the projector and notebook PC while the projector is \
in standby mode and before turning on
the power to the notebook PC.
In most cases the output signal from the notebook PC is not turned on un\
less connected to the projector before
being powered up.
NOTE: You can check the horizontal frequency of the current signal in the projector ’s menu under Information.  If it reads
“ 0kHz ”, this means there is no signal being output from the computer. (→ page  47 or go to next step)
• Enabling the computer ’s external display.
Displaying an image on the notebook PC ’s screen does not necessarily mean it outputs a signal to the projec-
tor.  When using a PC compatible laptop, a combination of function keys wil\
l enable/disable the external display.
Usually, the combination of the  ‘Fn ” key along with one of the 12 function keys gets the external display to\
 come
on or off.  For example, NEC laptops use Fn + F3, while Dell laptops use Fn + F8\
 key combinations to toggle
through external display selections.
• Non-standard signal output from the computer
If the output signal from a notebook PC is not an industry standard, the\
 projected image may not be displayed
correctly. Should this happen, deactivate the notebook PC ’s LCD screen when the projector display is in use.
Each notebook PC has a different way of deactivate/reactivate the local LCD screens as described i\
n the
previous step. Refer to your computer ’s documentation for detailed information.
• Image displayed is incorrect when using a Macintosh
When using a Macintosh with the projector, set the DIPswitch of the Mac adapter (not supplied with the projec-
tor) according to your resolution. After setting, restart your Macintosh for the changes to take affect.
For setting display modes other than those supported by your Macintosh a\
nd the projector, changing the DIP
switch on a Mac adapter may bounce an image slightly or may display noth\
ing. Should this happen, set the DIP
switch to the 13 ” fixed mode and then restart your Macintosh. After that, restore the DIP switches to a
displayable mode and then restart the Macintosh again.
NOTE: A Video Adapter cable manufactured by Apple Computer is needed for\
 a PowerBook which does not have a mini D-Sub
15-pin connector.
• Mirroring on a PowerBook
* When using the projector with a Macintosh PowerBook, output may not be s\
et to 1024 x 768 unless  “mirror-
ing ” is off on your PowerBook. Refer to owner ’s manual supplied with your Macintosh computer for mirroring.
• Folders or icons are hidden on the Macintosh screen
Folders or icons may not be seen on the screen. Should this happen, sele\
ct [View]  → [Arrange] from the Apple
menu and arrange icons.
