Let’s Check the Monitor and Its Power Supply
If your monitor will not turn on or display its menu,
check the following before assuming the monitor is faulty.
Wearing polarized sunglasses?
Remove them briefly and look at the screen again.
Polarized lenses can make an LCD screen appear very dark
or black at certain angles.
Disconnect power before inspecting fuses
or disconnecting and reconnecting cables.
-
Check the power button and power source.
Make sure the vehicle’s key or accessory switch is on
if your power connection requires it. Press the monitor’s
Power button, allow it time to start, then try Menu.
Notice whether the screen or any indicator lights come on.
If a button is stuck or damaged, do not force it.
-
Identify how the monitor receives power.
Are you using a cigarette-lighter style adapter,
a hardwire connection, a wall/AC adapter, or another supply?
Check the adapter and any separate power lead or harness.
Your wireless camera needs its own power.
A powered monitor does not establish that the camera
is receiving power. These checks are for the monitor;
camera power is checked in the no-picture path.
-
Check all applicable fuses.
Depending on the installation, there may be a fuse
in the power adapter, an inline fuse in the wiring,
and a separate fuse for the vehicle’s outlet or circuit.
On adapters with a removable fused tip, check the fuse
inside that tip according to the adapter’s instructions.
Replace a fuse only with the specified type and rating.
Never bypass a fuse or install a higher-rated fuse.
If a replacement fuse blows again, disconnect power
and contact Technical Support.
-
Check the power connections.
With power disconnected, inspect accessible connections
for looseness, corrosion, damaged wiring, or bent or
missing connector pins. Reconnect securely without forcing.
-
Vehicle plug-in adapter:
Check that it fits securely and the outlet supplies power.
If available, try another known-working compatible outlet.
A working outlet alone does not prove the adapter works.
-
Wall/AC adapter:
Check the outlet and adapter connections.
Note the adapter’s part number, output voltage,
and output current from its label.
A photo of the label can help Technical Support.
-
Hardwired installation:
Have your installer check power, ground, the supplying
circuit, and any required switched-power connection.
Leave wiring you cannot identify in place.
-
Compare with a known-working power adapter,
if available.
Use only a Dakota Micro-approved adapter confirmed
compatible with your monitor. A matching plug does not
establish the correct voltage or compatibility.
Change one item at a time, disconnecting power before
changing connections. Restore power and check the monitor.
Skip this test if you do not have compatible equipment.
Monitor operating, but still no camera picture?
Change your problem selection above to
“Camera won’t connect / no camera picture.”
Then answer the menu question to continue.
Still having trouble?

you use, which fuses you checked, whether the screen or
lights come on, and what changed during testing.
