TROUBLESHOOTING GUIDE 8
We have carefully tested and have found no
problems in the supplied MX2106AV unit. However,
we would like to offer the following suggestions:
8.1 LEDs ARE OFF
Cause 1: The 9V 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 9V adapter is installed.
Solution 1: Please use the ALTINEX supplied
external adapter (9VDC 500mA). If
one of the LEDs is still not on, call
ALTINEX at (714) 990-2300.
8.2 UNIT DOES NOT AUTO SWITCH
Cause 1: The manual switch is installed.
Solution: Remove the connection to the
INPUT SELECT jack. If a plug is
installed in the jack, auto-switching
is disabled. If the unit still does not
auto-switch, see Cause 2.
Cause 2: The video signal is bad.
Solution 1: Remove the input signals from the
switcher. If the IN 1 LED is off, call
ALTINEX at (714) 990-2300. If the
IN 1 LED is on, see Solution 2.
Solution 2: Connect a properly formatted
VGA-type signal to Input 2. If the
switcher does not switch to Input 2,
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
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.
Cause 3: Signal is bad or missing.
Solution 1: Make sure the switcher output is
connected to the monitor. If there is
still no display, see Solution 2.
Solution 2: Remove both inputs to the switcher
and connect the active signal from
the source to Input 1. If there is still
no display, see Solution 3.
Solution 3: Bypass the switcher and connect the
output of the source directly to the
monitor. If the display is good, then
call ALTINEX at (714) 990-2300. If
there is still no display, see Cause 4.
Cause 4: Cable connections are incorrect.
Solution: Make sure the cables are properly
connected. Also, make sure that the
continuity and wiring are good. If
there is still no display present, see
Cause 5.
Cause 5: The display has a problem.
Solution: Make sure the display is powered
and is turned on. If there is still no
display, please call ALTINEX at
(714) 990-2300.
