Troubleshooting
Video Noise
Check for an incorrect ground in the installation wiring. See specific examples of video
noise below, or visit
VGA Shadowing
Most of shadowing problems are due to shielding on the wire. Locate the point where
all of the shields are connected. Cut away the shields, one at a time, while viewing the
display on the screen to observe which shield is causing the noise. Cutting away one
shield at a time will allow you to focus and isolate the video noise issue.
Twisted pair wiring is prone to video noise. ECS VGA Wire
(Detailed under "Video Wiring Suggestions") is recommended.
Snow or Sweeping Lines
Lines that slowly sweep up and down are a result of AC noise. This AC noise can be
generated by a power cart on the aircraft. Take the power cart off of the aircraft. Be
careful of inverter wiring, which can also cause noise. Stand off the wires, if necessary.
If snow or sweeping lines persist, it is possible that the ground is at an incorrect point in
the aircraft. Try moving the ground to another location.
No power to Monitor, or No video Input
• Verify correct wiring. Check the base receptacle connectors for possibly damaged
pins.
• Check that the video source is:
1. Powered on,
2. In Play mode, and
3. Displaying video.
Color Distortion
•
Adjust brightness and contrast settings using the buttons on the monitor.
Remote Control Inoperable
•
Confirm that the infrared eye on the LCD screen is visible
