ProblemsSolutions
If the soundbar does not turn ON• Check if the soundbar power supply’s AC cord is plugged into a working AC outlet
and that the power supply is plugged into the soundbar.
If the subwoofer does not turn ON• Check if the subwoofer’s power cord is plugged into a working AC outlet.
• Press the Power switch of the subwoofer.
• Check if the subwoofer’s AC fuse has blown. See Subwoofer Rear Panel Controls.
If there is no sound coming from both the soundbar and the subwoofer• Check if soundbar is ON (the Power Indicator should be white).
• Check if the cable connecting the TV or other source component to soundbar is
properly connected at both ends.
• Check if the soundbar’s Source Selector is set to the correct source and that
source is playing an audio signal.
• Check if the system is not muted. If the system is muted, press the volume buttons
to un-mute the system.
• Check if the soundbar’s volume is not turned all the way down (the lowest setting
of the Volume Down button will mute the system).
If there is no sound coming only from the subwoofer• Check if the Subwoofer Volume Control is not turned all the way down using the
remote control.
• Check if the wireless connection is still active (Blue LED constant in the back of
the subwoofer). If the LED is flashing blue, then restart the pairing process.
• Move the subwoofer closer to the soundbar. The maximum wireless operation
distance is 50 feet (15.3 m).
If the soundbar’s sound is distorted• Check the source component to see if the distortion is coming from it, and not
from soundbar.
If there is sound from the system, even when the soundbar’s volume is turned all
the way up
• If the TV or source component is connected via a variable output, check its
instructions if the output is not turned down too low.
If the bass output is not loud enough• Turn up the subwoofer’s volume using the remote control.
• Move the subwoofer at a corner of the room.
• Move the subwoofer closer to the seating location.
The volume is reset when I turn on the soundbar• This is actually an inbuilt feature of the soundbar. If the soundbar is playing at
more than 80 percent of maximum volume and the power is turned off, the volume
of the soundbar is automatically reset to 80 percent of the maximum volume when
