TROUBLESHOOTING GUIDE 8
We have carefully tested and found no problems in
the supplied SW104-130 unit. However, we would
like to offer the following suggestions:
8.1 LEDs ARE OFF
Cause 1: The power adapter is installed
wrong.
Solution 1: Make sure the adapter output is
connected to the power input jack on
the unit. If one of the LEDs is still not
on, see Solution 2.
Solution 2: Ensure the adapter is plugged into
an AC outlet that has power. If the
adapter has AC power and the LEDs
are still off, see Cause 2.
Cause 2: The wrong power adapter is
installed.
Solution 1: Please use the ALTINEX supplied
external adapter. If one of the LEDs
is still not on, please call ALTINEX
at (714) 990-2300.
8.2 UNIT DOES NOT AUTO-SWITCH
Cause 1: The remote override switch is
installed.
Solution: Remove the connection to the Input
Select jack on the unit. If a plug is in
the jack, even without a switch
connected, the SW104-130 will not
auto-switch properly. If the unit does
not auto-switch with the plug
removed, see Cause 2.
Cause 2: The control switch is not in the
auto position.
Solution: Switch the Control Switch to the
auto position. If the unit does not
auto-switch, see Cause 3.
Cause 3: The signal is not active or is
improperly formatted.
Solution 1: Remove the input signals from the
switcher. If the Input 2 LED is off,
call ALTINEX at (714) 990-2300. If
the Input 2 LED is on, see
Solution 2.
Solution 2: Connect a properly formatted video
type signal to Input 1. If the switcher
does not switch to Input 1, see
Solution 3.
Solution 3: Bypass the switcher and connect the
output of the source directly to the
display. If the display is good, then
see Cause 4.
Cause 4: The wrong power adapter is
installed.
Solution 1: Please use the ALTINEX-supplied
external adapter. If the unit still does
not auto-switch, please 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: Manual override is ON.
Solution: Make sure there is nothing
connected to the Input Select port
on the switcher. If there is nothing
connected, see Cause 3.
