“BLACK SCREEN”
1) Check that your camera head LEDs are powered on.
a) If they are not, and your LCD is “Black Screen”:
i) Make sure that your power supply is plugged into a wall receptacle that has
confirmed good power.
ii) Make sure that your “Power” switch is in the “on” posion.
iii) Check that your pin connector is sll plugged into the back of your camera head
(Refer to Head Removal/Installaon Guide – NON MYCRO ONLY)
iv) If you sll have “Black Screen” AND no power to your LEDs, please call for technical
assistance.
b) If the LEDs are on, proceed to next step.
2) Press the Power Buon on your LCD. If this does not turn it on, try pressing the Power Buon on
your remote control. If your LCD sll does not turn on, proceed to the next step.
3) Check that your 6-pin connecon from the LCD to the controller is securely pushed in
a) NOTE: This connecon is located INSIDE your Main Controller. Please call for technical
assistance for properly accessing this connecon.
b) This connecon is a PUSH/PULL connector – DO NOT TWIST CONNECTION
c) Check the NOTCH PATTERN to ensure that the connector is plugged in correctly. DO NOT
FORCE CONNECTOR TOGETHER.
d) Again, try to turn on your LCD with the Power Switch. If this does not work, try pressing the
Power Buon on your remote control.
4) Sll having lights on the head, but a “Black Screen”, route your video signal to a known working
monitor/television. Simply run an RCA cable from the SILVER video jack on your control panel to
the VIDEO INPUT of any television. Switch the acve input on the TV to that input and see if you
now have video on THAT screen.
a) If you do get video on a separate TV, then a problem may exist in your LCD or harness.
b) If you do not get video on a separate TV, then a problem may exist in your camera head,
control board, or wiring in between.
c) In either of these cases, please call for technical assistance.
5) If you are sll experiencing a “BLACK SCREEN”, please call for technical assistance.
