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.

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.
