Troubleshooting FAQ's
Being
the certified service and repair center we
field a lot of questions every day. We have
gathered a few here to provide you some answers…
Feel
free to contact our service experts via email
for any specific questions!
Q:
My projector powers up and the menu works,
but I do not have an image.
A:
First make sure the right source is selected.
Second, if your projector has the capability,
make sure the RGB source is set to Standard
and not to any of the custom settings.
If the RGB is set to custom change it back
to standard by pressing the Adjust +/- until
it reads Standard. Press the Enter button
or trigger on the remote control to make the
changes.
If
the image is still shifted over or blank,
try turning off the local display or your
laptop. To do this most laptops have a function
key with "LCD/Monitor" or a picture
of a monitor above it. There will also be
a "FN" Key. Hold down the "FN"
and press that function key momentarily. You
may do this repeatedly to toggle through the
different options on the laptop. (I.E. LCD
On/Output Off, LCD Off/Output On)
If
the laptop still displays nothing and the
monitor output works make sure you are not
running the computer at a refresh rate that
may be too high for the projector, but not
too high for your local monitor. The projectors
specifications are listed in the user’s
manual. To avoid complications use the INF
file in Windows 95/98 to let your computer
know the limits of your projector.
Q:
Computer does not sync up. (Image could be
split, no image at all, or the whole image
is not on the screen).
A:
First make sure the right input is highlighted
in the Source Menu. Second, makes sure the
RGB source is set to Standard and not to any
of the custom settings.
If
it is change it back to standard by pressing
the Adjust +/- until it reads Standard. Press
the Enter button or trigger on the remote
control to make the changes.

Q:
The projector will not project but the monitor
output works fine.

First
make sure the right input is highlighted in
the Source Menu. Second, makes sure the RGB
source is set to Standard and not to any of
the custom settings.

Q:
The image looks noisy or of poor quality.
A:
The best picture is obtained from running
you computer source at the same resolution
as the projector. For example, if you have
an SVGA (800X600) projector (native resolution)
the computer should be run at 800X600. It
can be run higher (I.E 1024X768) but it will
have to compress the image and it will lose
some detail.
Q:
The text in my presentation looks funny or
distorted.
A:
The
best picture is obtained from running you
computer source at the same resolution as
the projector. For example, if you have an
SVGA (800X600) projector (native resolution)
the computer should be run at 800X600. It
can be run higher (I.E 1024X768) but it will
have to compress the image and it will lose
some detail.
Q:
My image flashes in and out and/or it is flagging
at the top.
(MT-830/1030/1035, + series)
A:
You may be running too long of a cable and
need a distribution amp to boost the signal
to the projector. Video can be sent via S-video
cable without a distribution amp about 100
feet at the most using good quality shielded
cable. RGB cable can be sent without a distribution
amp about 25-30 feet using an HD15 pin cable.
If you use shielded coaxial 5-wire cable it
can be run up to 60 feet without any problems.
Q:
How long of a cable can we run?
A:
Video can be sent via S-video cable without
a distribution amp about 100 feet at the most
using good quality shielded cable. RGB cable
can be sent without a distribution amp about
25-30 feet using an HD15 pin cable. If you
use shielded coaxial 5-wire cable it can be
run up to 60 feet without any problems. Signal
cable (VGA) can be sent 20-25 feet without
a distribution amplifier.
Q:
Which signal cable should be used with what
projector?
A:
Any 15-pin to 15-pin VGA cable can be used
with the MT & LT series projectors.
Q:
During my presentation, the projector will
suddenly blank out then zoom in on the image.
A:
Turn off the Auto Mode in the Image Adj. Menu
of the projector or don’t use black
borders in your presentations.
Q:
My projector powers off by itself after 5
minutes.
A:
The
Power off feature is turned on. This will
power off the projector if no signal is applied
for 5 min. to prevent wasting the lamp life.
If you do not want this to happen simply turn
off this feature.
Q:
Can
I use both S-video and video at the same time
and switch between them?
A:
Yes. If your projector has both of these input
types (Video & S-Video) both inputs can
be connected at the same time and you can
use the remote or the menu to switch between
them.
Q:
My
image is bigger on one side than the other
or the image is not square.
A:
All LCD Projectors will project a square image.
If the image is not square the problem will
be in the angle the projector is aimed at
the screen. Either pointed too high causing
a keystone effect or side to side causing
the image to be larger on one side than the
other. If your projector has a keystone correction
feature, this allows for instances where the
projector must be at an awkward angle. Use
this feature to properly align your image.
