8. Troubleshooting Guide
We have carefully tested and found no problems in the supplied
MT103-102; however, we would like to offer suggestions for the following:
8.1 LED is Not Lit
The LED should be on and red when power is applied and there is no video
signal present. If the LED is on and green, the unit is receiving power and a
SYNC signal
Cause 1: Card cage is not plugged in.
Solution: Plug in the card cage. If the LED lights the problem is solved.
If the LED is still not on, see Cause 2.
Cause 2: Card is not plugged in all the way.
Solution: Push the card in all the way. If the LED is still not on, see
Cause 3.
Cause 3: 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 the card works
in other slots and the LED lights, the problem is the card cage
slot. The card cage may require service, please call ALTINEX at
[phone]. If the other slots do not work and the LED is
still not on, see Solution 2.
Solution 2: Take any other known good card with an LED and verify that
the slot used is good by seeing if the other card’s LED lights in
that slot. If it lights, then the original card may be the source
of the problem. Call ALTINEX at [phone].
8.2 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: The card output is not enabled.
Solution: Turn on the card outputs. See RS-232 accessible commands in
Section 7. If no display is present, see Cause 3.
Cause 3: 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 4.
Cause 4: The display has a problem.
Solution: Make sure the display is powered and turned on. If there is
still no display, please call ALTINEX at [phone].
8.3 Card is Not Recognized
Cause 1: The card is not recognized.
Solution: Reset the card cage by sending the [RES] command, or turning
the system power off and then on again. Send the [C]
command to see if there is communication with the card. If
there is no feedback, see Cause 2.
Cause 2: Card is not plugged in all the way.
Solution: Push the card in all the way. Reset the system and send the [C]
command. If the card is still not recognized, see Cause 3.
Cause 3: 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
[phone]. 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.
