Troubleshooting (continued)
There is no sound from one of the front
speakers.
• Connect a pair of headphones to the PHONES
jack to verify that sound is output from the
headphones (see page 18).
If only one channel is output from the
headphones, the component may not be
connected to the amplifier correctly. Check that
all the cords are fully inserted into the jacks on
both the amplifier and the component.
If both channels are output from the headphones,
the front speaker may not be connected to the
amplifier correctly. Check the connection of the
front speaker which is not outputting any sound.
There is no sound or only a very low-level sound
is heard.
• Check that the speakers and components are
connected securely.
• Check that you have selected the correct
component on the amplifier.
• Check that the headphones are not connected.
• Press MUTING if muting function is activated.
• The Thermal Protection has been activated
because the amplifier is overheated
(“OVERHEAT” flashes in the display). Turn off
the amplifier, leave the amplifier for a while,
then turn on the power again.
• The Over Current Protection has been activated
because of low impedance or short circuit
(“PROTECT” flashes in the display). Turn off
the amplifier, eliminate the short-circuit problem
and turn on the power again after about
20 seconds.
The left and right sounds are unbalanced or
reversed.
• Check that the speakers and components are
connected correctly and securely.
• Adjust balance parameters in the LEVEL menu.
There is severe hum or noise.
• Check that the speakers and components are
connected securely.
• Check that the connecting cords are away from a
transformer or motor, and at least 3 meters away
from a TV set or fluorescent light.
• Move your TV away from the audio components.
• The plugs and jacks are dirty. Wipe them with a
cloth slightly moistened with alcohol.
There is no sound from the center speaker.
• Make sure the sound field function is on (press
SOUND FIELD +/–).
• Select a sound field containing the word
“CINEMA” or “VIRTUAL” (see page 19–20).
• Adjust the speaker level (see page 17).
• Make sure the center speaker size parameter is
set to either “SMALL” or “LARGE” (see page
16).
There is no sound or only a very low-level sound
is heard from the surround speakers.
• Make sure the sound field function is on (press
SOUND FIELD +/–).
• Select a sound field containing the word
“CINEMA” or “VIRTUAL” (see page 19–20).
• Adjust the speaker level (see page 17).
• Make sure the surround speaker size parameter is
set to either “SMALL” or “LARGE” (see page
16).
There is no sound from the active sub woofer.
• When you select NORM. SP., make sure the sub
woofer is set to “S.W. YES” (see page 17).
• Check that “2CH ST.” is not selected (see page
20).
“PCM--kHz” appears on the display.
• The sampling frequency is more than 48 kHz.
Change the input player setting to 48 kHz.
The surround effect cannot be obtained.
• Make sure the sound field function is on (press
SOUND FIELD +/–).
There is no picture or an unclear picture appears
on the TV screen or monitor.
• Select the appropriate function on the amplifier.
• Set your TV to the appropriate input mode.
The remote does not function.
• Point the remote at the remote sensor on the
amplifier.
• Remove any obstacles in the path between the
remote and the amplifier.
• Replace both batteries in the remote with new
ones, if they are weak.
• Make sure you select the correct function on the
remote.
• If the remote is set to operate the TV only, use
the remote to select a source or component other
than TV before operating the amplifier or other
component.
