6.7 Fault Summary
The following troubleshooting tips were designed to help diagnosing and correcting minor
operational problems in the unlikely event that there are difficulties encountered with the SE4000.
If all of suggested solutions are tried and the unit still fails, contact the Radyne ComStream
Customer Service Department.
Front Panel Symptoms
Problem:
The front panel is not enabled, is in view-only mode, does not accept commands or button
pushes.
Solutions:
The front panel may be in lock-out mode. Unlock the front panel.
Problem:
No video output from the decoder.
Solutions:
Verify that the video cabling to the encoder is correctly connected.
Verify that the cabling from the decoder to the monitor is correctly connected.
Ensure that the SE4000 is configured for the video input source that is being provided.
Problem:
No audio output from the decoder.
Solutions:
Verify that the audio cabling to the encoder is correctly connected.
Verify that the cabling from the decoder to the audio monitor is correctly connected.
Ensure that the SE4000 is configured for the audio input source that is being provided.
Problem:
No audio or video output from the decoder.
Solutions:
Data link problem between the encoder and decoder. This could be caused by excessive
satellite noise or other data corruption.
Problem:
Green or black stripes across the middle of the video.
Solutions:
Noisy or “dirty” AC power. Change to a “clean” power source, or use an AC power filter or
power conditioner.
Ensure that the input source is in the proper format and conforms to specified input levels.
Remote Unit Monitor Symptoms
Problem:
No sign-on message on the remote terminal after power-up.
Solutions:
Ensure that the remote unit and the SE4000 are turned on and plugged into an active AC
outlet.
Verify that the baud rate and parity of the remote unit communications package match the
factory setting of the SE4000 remote control interface. Factory settings are 38400 baud, 8
data, no parity, and 1 stop bit.
Verify that the cable between the terminal, the SE4000, and the Null Modem Adapter are
properly connected.
