KD-CDA3 Operating Instructions

For “VGA” (RGBHV) operation, verify that the Sync is either present on the Green connector or the H & V connectors. Make sure you have properly connected Sync from the Output jacks of your “Source” to the Input of your KD-CDA3, and that the corresponding Outputs of the KD-CDA3 are properly connected to your Display(s).

Note: For Component Video (YPbPr), sync is present on the “Y” Channel.

PROBLEM: You are able to view a picture on the Display(s), but the image is Black and White, Green, or Pink in Nature.

This is indicative of a mismatch between “Source” and Display devices in the Video connections. Make sure that your Source and Displays are all of the same format. For example, if the Source outputs “Component Video” (YPbPr) then the connections to your Display(s) must also be via the “Component Video” path (and not the VGA).

Make sure that the Component Video (YPbPr) or “VGA” Video (RGBHV) connec- tions are properly maintained throughout the entire chain from the Source, to the KD-CDA3, to your Display device(s).

PROBLEM: There is a picture but it is “scrolling” across the screen of one or more of your Display devices.

This happens when the Input signal from your Source device is not compatible you’re your Display, or if there is a problem with the Sync signal(s).

For example, if one or more of your Displays connected to the Output of the KD- CDA3 is not capable of handling HDTV-compatible video signals, make sure that the “Source” device is set to output SD- compatible signals (Standard Definition or 480i).

For “VGA” (RGBHV) operation, verify the presence of the Sync signal. Note: For Component Video (YPbPr), sync is present on the “Y” Channel.

KD-CDA3 Operating Instructions

PROBLEM: You are able to view a picture but there is interference, noise, or hum bars visible on the image on one or more of your Display devices.

This can happen when crossing power lines when routing the cable from the “Source” device to the KD-CDA3, or when routing the cables from the KD-CDA3 to your Display device(s).

If crossing power lines is inevitable, make sure to use heavy, shielded, high-quality Video and Audio cables.

Sometimes using a shielded and noise filtering surge protector can eliminate noise in power lines.

PROBLEM: There is no Audio from your Audio system.

Check to make sure that the volume is turned up to an audible level on the “Source” device as well as the Display device. If you still encounter a problem, then:

Make sure that the Audio connections were properly configured, and that your dis- play has speakers. Check the connections from start to finish for the Left (white) and Right (red) stereo Audio channels.

When using the Digital Audio connection (“PCM” or coaxial audio), make sure that the Display device is capable of decoding this compressed bit stream of audio information. Most often when using the “PCM” audio function, the audio will be connected to an AV-Receiver or amplifier capable of decoding Dolby Digital®.
