Follow this procedure to troubleshoot if there is no sound or audio through the speakers when watching television programming.
- Verify that an AV cable is securely connected to the AUDIO OUT jack on the television or set-top box.
- Verify that the other end of the AV cable is securely connected to an AUDIO IN jack on the receiver.
- Ensure the receiver is tuned to the same input in which the AV cable is connected.
- Ensure the television or set-top box menu is setup to allow audio to be output from the AUDIO OUT jack.
IMPORTANT: If the AUDIO OUT jack on the TV or set-top box is a variable output, it may be necessary to increase the volume level on the television or set-top box.
NOTE: Consult the instruction manual for the set-top box or television to verify this setting. If necessary, contact the television or set-top box manufacturer for further information.
- Increase the volume level on the receiver.
- If the issue is still not resolved, connect the AV cable to a different input on the receiver.
- Tune the receiver to the input in which the AV cable is now connected.
- If there is still no sound, replace the AV cable.
NOTE: If there is still no sound after completing all the steps above, connect another source (such as a VCR or DVD player) to the input jacks on the receiver to check if sound can be received from other devices. If sound can be received by other devices, then the problem may be with the set-top box or television. If there is still no sound, then the receiver may require service.
