3G HDSDI: On certain model monitors there is an option for 3G HDSDI. The SDI signal
requires a 75 OHM coax cable. If you are unable to see a signal from your camera using SDI
check the cable first. The SDI status light should be solid green when it is receiving a signal
and flash when there is no signal. If the status light does not light up at all the power
connector inside the monitor that goes to the 3G board may have come loose. If the status
led is solid green but no video the HDMI adapter plug may have come loose from the
controller you may need to open the case and check the connections.
D.
VGA: there are a few cameras on the market with VGA out. You can check the monitor with
a computer just attach the other end of the cable to a laptop or desktop computer and
enable the computer’s VGA Port.
Section C - Your monitor turns on but the screen is solid black or solid white.

Section D - Your monitor is not powering on.
1.
Plug the supplied 120-240V AC to 12V DC power supply into the monitor. If the Red Status LED
comes on go to Step 2. If it does not come on troubleshoot the power supply. Our monitors use
12v regulated power either from the supplied power supply or from a battery pack. With a volt
meter make sure the power connector is showing 12V DC the center pin is positive (+) the
outer shell is negative (–). If the power supply is good go to step 2
2.
Open the monitor up and check inside for loose connections.
A.
If the red power light is not coming on check the large cable that carries power from one
side of the board to the other.

Also check these pins for 12V and 5V.

If red power light comes on and pressing the power button does not make the green led
come on try removing the LVDS cable from the controller.
