, Connect a pair of headphones to the PHONES jack
to verify that sound is output from the headphones
(see "qf SPEAKERS button" and "PHONES jack"
on page 25).
If only one channel is output from the headphones,
the component may not be connected to the
receiver correctly. Check that all the cords are fully
inserted into the jacks on both the receiver and the
component.
If both channels are output from the headphones,
the front speaker may not be connected to the
receiver correctly. Check the connection of the front
speaker which is not outputting any sound.
