Solution: Push the card in all the way. Reset
the system and send the [C]
command. If the card is still not
recognized and the LED is not on,
see Cause 4.
Cause 4: Card cage slot has a problem.
Solution 1: Test the card in other slots of the
card cage. If the slot was damaged,
the card may work in other slots. If
other slots work and the card is
recognized, the problem is the card
cage slot. The card cage may require
service. Call ALTINEX at
(714) 990-2300. If the other slots do
not work, see Solution 2.
Solution 2: Take any other known good card and
verify that the slot used is good by
seeing if the other car is recognized
in that slot. If it is, then the original
card may be the source of the
problem. Call ALTINEX at
(714) 990-2300.
8.2 LED IS NOT GREEN (VGA)
Cause 1: There is no power.
Solution: Disconnect the video input from the
MT103-122 and verify the LED is ON
and RED indicating power is present.
Reconnect the computer's video
output. If the LED is still not GREEN
see Cause 2.
Cause 2: There is no Sync signal.
Solution: Verify the computer output is
operating correctly by connecting it
directly to the local monitor. If the
display is good, call ALTINEX at
(714) 990-2300.
8.3 NO DISPLAY
Cause 1: The source has a problem.
Solution: Check the source and make sure that
there is a signal present and all
source connections are correct. If the
source is working and there is still no
display, see Cause 2.
Cause 2: Cable connections are incorrect.
Solution: Make sure that cables are properly
connected. Also, make sure that the
continuity and wiring are good. If
there is still no display present, see
Cause 3.
Cause 3: There is no input signal.
Solution: Verify the card is receiving a valid
signal at the input using the Signal
Detect command, [SIG]. See RS-232
accessible commands in
Section 7. If no signal is detected,
see Solution 2. If a signal is
detected, see Cause 4.
Cause 4: Equalization is set too high.
Solution: Make sure the equalization is set to
minimum to start. If controlling the
equalization using the built-in
potentiometer, verify the EQ switch
on the board is set to HW. See
DIAGRAM 4 for details.

Cause 1: The source has a problem.
Solution: Check the image on the local monitor
and verify the quality is good. If the
local image is good, see Cause 2.
Cause 2: Video equalization required.
Solution: Adjust the VIDEO EQUALIZATION
on the MT103-122. Long cable runs
may require adjustment on both the
MT103-122 and the receiver. If the
image is still not correct, call
ALTINEX at (714) 990-2300.
