Troubleshooting

HDMI signals run at a very high frequency and are especially susceptible to bad video connections, too many adapters,

or cables that are too long. To avoid the loss of an image or introduction of image jitter, follow these guidelines:

•The HDMI cable on the input to the transmitter or the output of the receiver should not exceed 10' (3 m).

•Use only cable designed for HDMI signals.

•Limit or avoid the use of adapters.

•If the display exhibits a flashing black or blue screen, snow, or other distortion, a non-HDCP compliant display may be receiving an HDCP-encrypted signal.

Check for an HDCP problem by ejecting the DVD from the player. If the display distortion stops and the DVD menu or screen saver image is clear, the problem is HDCP-related.

Application Examples

Audio conversion

Figure 2-27 shows a standard installation with HDMI video and an audio input. The HDMI 201 A D Tx converts the video input into two proprietary TP outputs. The Tx outputs the audio directly on a captive screw connector.
