Troubleshooting
If you experience any of the following difficulties while
using the amplifier, use this troubleshooting guide to
help you remedy the problem. Should any problem
persist, consult your nearest Sony dealer.
No sound output.
/ Connect the audio connecting cords firmly.
/ Connect the amplifier and other audio components
correctly.
/ Turn INPUT SELECTOR to the appropriate programme
source.
No audio from one channel or unbalanced speaker
output.
/ Turn BALANCE to adjust the balance.
/ Check the speaker and input connections of silent
channel.
Weak bass or treble.
/ Adjust the TONE controls.
/ Change speaker positions or room conditions to
eliminate obstructions in sound path.
Distorted sound.
/ Improperly selected input signal.
/ Insufficient input capacity of speakers. Lower the
volume.
Lack of bass or ambiguity in instrument positions.
/ Speaker cord and terminal polarity are reversed.
Reconnect the cords with correct polarity.
Hum or noise.
/ Ground the turntable system (see page 5).
/ Connect the audio connecting cords firmly.
/ The amplifier is picking up interference from a TV set.
Move the amplifier away from the TV set or turn the TV
set off.
The remote does not function (TA-FE910R/FE710R/
FE610R/FE510R/FE310R only).
/ Remove any obstructions between the remote control
sensor on the amplifier and the remote.
/ Point the remote towards the remote sensor on the front
of the amplifier.
/ The remote is too far from the amplifier. Move closer to
the amplifier.
/ Replace the batteries in the remote.
The PROTECTION indicator lights up (TA-FE910R/FE710R/
FE610R only) and/or sudden loss of audio.
/ Check if a short-circuit has occurred. Turn off the
amplifier and check the connected components and
speakers.
