The following are some of the most commonly encountered receiver problems.
Cable specific problems

The cable is not properly plugged in.
• Check that the cable connector is attached to the correct receiver port.
• Unplug the cable, then securely and properly reconnect it to the receiver.
• See “DELTA Receiver” on page 19 and “Connector Specifications” on page 82 for
information on the receiver’s connectors.

The cable is damaged.
• Use an undamaged cable. Contact your Dealer to replace the cable.

a Computer” on page 25) and start TriVU.
