SB 30
Troubleshooting
If your SB 30 system isn’t performing the way you think it should, check to see if the problem is covered in this section before calling your dealer or contacting a Harman Kardon
representative.
Problem Solution
The soundbar does not turn on (the Power LED is off): • Check that the soundbar’s power cord is plugged into a working AC outlet.
• Check that the soundbar’s Power switch is in the “On” position.
• Check if the soundbar’s AC fuse has blown. See Soundbar Rear-Panel Controls
and Connections: AC Fuse Holder, on page 4, for instructions on checking and
changing the fuse.
• Check if the soundbar’s voltage selector switch is set in the incorrect position for
the AC voltage in your area. CAUTION: If the switch is set in the incorrect position,
do not change the switch position or attempt to turn the soundbar back on.
Unplug the soundbar from the wall outlet and take it to an authorized Harman
Kardon service center.
The subwoofer does not turn on (the Power LED is off): • Check that the subwoofer’s power cord is plugged into a working AC outlet.
• Check that the subwoofer’s Power switch is in the “On” position.
There is no sound coming from both the soundbar and the subwoofer
(their Power LEDs are amber or blue):
• Check that the soundbar is on (the Power LED is blue).
• Check that the cable connecting the TV or other source component to the soundbar
is properly connected at both ends.
• Check that the soundbar is set to the correct input source (one white Status LED
glows for optical digital, two white Status LEDs for coaxial digital, and three white
Status LEDs for analog) and that the input source device is playing an audio signal.
• Check that the system is not muted (when the system is muted, the soundbar’s
Power LED flashes blue). If the system is muted, press the remote control’s Mute
button to un-mute the system.
• Check that the soundbar’s volume is not turned all the way down.
There is no sound coming from just the subwoofer (the Power LED is amber or blue): • Check that the Subwoofer Volume control is not turned all the way down (fully
counterclockwise).
• Check that the Wireless Code switches on the subwoofer and soundbar are both
set to the same setting number.
• Move the subwoofer closer to the soundbar. The maximum wireless operation
distance is 50 feet (15.3m).
The soundbar’s sound is distorted: • Check the source device to see if the distortion is coming from it and not from
the soundbar.
The system’s sound is too quiet, even when the soundbar’s volume is turned all
the way up:
• If the TV or source component is connected via a variable analog output, check its
instructions to be sure that the output is not turned down too low.
The bass output is not loud enough: • Turn up the subwoofer’s Volume control.
• Move the subwoofer into a corner of the room.
• Move the subwoofer closer to the seating location.
