Subwoofer troubleshooting guide
If you have a problem with your subwoofer, please consult this troubleshooting section for possible solutions.
If, after consulting this section, the problem remains unresolved, please contact your dealer for more
information and/or help.
This troubleshooting section contains information on how to solve the most common subwoofer problems,
but it does not and cannot cover every eventuality. It is possible that you won't find your problem, cause and
solution in this section due to differences between various connecting devices.
Problem
Possible cause
Solution
Speaker does not turn on with
mains power
Defective fuse
Check the fuse, which is located
under the power input, to rule out
of it's blown or not. If it is blown,
replace it with a new fuse of the
same type and class.
Problem with the power cable
Check that the power cable is
plugged into an active power
socket and the subwoofer properly.
Try using another cable of the
same type to determine if there's a
problem with the power cable and
if there is, the problem cable
needs to be replaced.
Speaker doesn't turn on
Check if the power switch on the
back of the speaker is set to the
'on' position.
Power LED doesn't light up
If the subwoofer is connected to an
active power socket, the fuse has
been checked and the power
switch is ON but the power LED is
not lighting up, there may be a
problem with subwoofer itself. In
this case, the subwoofer should be
turned off again and you should
contact your dealer for more help.
