Frequently Asked Questions
- The projector's light is on
but why isn't there a projected image on the screen?
This problem is most likely caused by one of the following.
A. Be sure that the doors, located on the underside of the projector, are
open (if
applicable).
B. Pull the power cord completely out through the open doors of the
projector (if
applicable).
C. Stand the projector up on it’s four legs (if applicable).
D. Another possibility may be that the mirror inside the unit is hung up on an
internal part and has not dropped into proper position. Please contact our service
representative at 1-800-676-2487.
Why do the lamps burn out quickly in my
Dukane Projector?
Many variables affect lamp life. Temperature and voltage have the largest impact on lamp
life. In warmer environments, lamps will not last as long as in cooler environments. If
the line voltage at the outlet is in excess of 120VAC, lamp life will be decreased
significantly. Even an increase of 1VAC to the 120VAC at the outlet can dramatically
shorten lamp life.
The lamps manufactured brand also has an affect on lamp life.
Your Dukane projector is shipped with quality lamps. We highly
recommend both GE and Sylvania brand lamps. Other lamp
manufacturers, while offering a savings in price, may only last a
fraction of the life that GE and Sylvania lamps do.
Some other tips to help you get the most out of a lamp are:
A. Allow the projector a cooling period before moving it.
B. Remove the lamps before transporting the projector.
C. If the projector is going to be stored away, store the lamps separately. Reinstall the
lamps when you are ready to use the projector again.
D. When installing lamps, be sure the lamps are seated completely. The tendency is to stop
at the first sign of resistance. Continue to apply force at the base of the lamp
until you are sure the lamp is secure.
E. Do not touch the lamp with bare fingers. If you accidentally touch the lamp, be sure to
clean the lamp with alcohol before powering the projector on.
F. Do not switch to the spare lamp (where applicable) without first shutting the projector
off.
G. When removing lamps, use lamp ejectors while at the same time lifting up on the base of
the lamp with your fingers (caution - allow lamps to cool before replacing!).
* Refer to the lamp chart for expected typical
lamp life.
Why does the lamp on my High Intensity
projector shut off after only a few minutes?
Most likely, the lamp needs to be changed. To be sure, turn the projector on. As soon as
the lamp shuts off, turn the power switch off and then back on immediately. If the lamp
immediately lights again, then the lamp needs to be changed. Refer to the manual for
replacement.
In the event that the lamp did not light again, call our technical service representative
at 1-800-676-2487.
Why is the projected image from my Dukane
projector cutoff on the left/right/bottom/top?
The computers output resolution must match the Dukane
projector/panel's "native" resolution. To configure the
computers video output to the appropriate resolution (i.e. SVGA
800x600, XGA 1024x768):
A. Connect the Dukane product to the computer and power the projector "on"
before the computer.
B. Set the notebook resolution to either SVGA (if applicable) or VGA.
-In Windows 95, select "Control Panel", "Display" icon,
"Settings", move resolution bar in "Desktop Area" to adjust
resolution.
C. Restart Windows.
Minor sync and image adjustments may be necessary. If the above fails to rectify the
problem, it may be necessary to configure some notebook computers to display video only on the
external video port. This is typically done through a combination of
keystrokes (such as a
FN&F4 key) or maybe a hardware setup program. Refer to your computer’s owner
manual for details.
Note: Some Data/Video projectors will actually display a
higher resolution than it's specified "native" resolution.
However, the image will be compressed to fit the native resolution
screen size (typically done by discarding every other line of
information). This may introduce some "jaggedness" to the
projected image.
The Data/Video projector displays an image
when it is first turned on but as soon as Windows starts, the image
just flickers or does not appear at all.
First check the resolution of your computer. You will need to make sure that the video
driver is set display the appropriate native resolution of the
projector. To change resolution, refer to question # 4.
It may be necessary to configure some notebook computers to display
video only on the external video port. This is typically done

Where can I find the cable for my Dukane data projector. What is the
part number and how do I order it?
Refer to the cable chart, then contact our service
representative at 1-800- 676-2487, to place your order.
Does Dukane have a discounted product
available?
We sometimes have "B" stock product that cannot be sold as new.
As inventory changes daily, please contact a service representative at 1-800-676-2487 for a
more current list.
Why is the projected image blurry around the
edges?
This problem is most likely the result of the projector being too close to the wall or
screen. If the image is blurry around all edges uniformly, try backing the projector away
from the wall to approximately 6 feet and focus.
If the image is only blurry on top/bottom/either side, the head will need adjustment.
Contact our service department at 800-676-2487 for assistance in adjusting the head alignment.
I cannot locate the power switch on my Dukane
Data/Video projector.
Some Dukane models have a unique power design. These projectors
do not have a conventional power switch. Once the unit is plugged
into a power outlet, the projector is in a "ready" state.
The main circuits of the projector are not powered on until the
appropriate "operate" button is pressed.
To power the unit off, simply press the applicable "operate"
or "standby". This will power off all main circuits.
After the projector goes into standby mode, it is safe to remove the
power cord. It is also completely safe to leave the projector
plugged into the outlet.
This exceptional and unique design, allows for a more complete cooling of the lamp and
proper ventilation for other critical components. This ultimately insures longer lamp life
and longevity of the product.
