Troubleshooting
Video Noise
Check for an incorrect ground in the installation wiring. See specific examples of
video noise below, or visit
http://flightdisplay.com/Grounding.pdf
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.
