Recently my house experienced an electrical surge during a thunderstorm. The sub-woofer powers on, but just makes a constant thumping noise. I replaced the fuse, but it makes the same noise. I was wondering if it is blown or if this problem sounds familiar and do you think it's repairable? I figured the sub-woofer has some kind of chip in it since the other speakers won't work without the sub and it just needs to be replaced.

Hi Cliff. the control board (as seen here: http://www.ebay.com.au/itm/like/251052948534?lpid=87 ) May be the only option. But once one thing has gone others may follow, ie Even the screen itself may have been hurt. I would highly suggest to throw it out and just buy another screen. Note, that model does NOT come with any 'fuses' inside, hence probably why it sparks still.
there is an electronic part that needs replacing here..As far as I remember this is common with a faulty condensator...or the transformer itself..there are some ways to fix this but you will need the right tools & expertise.
The pop from other electrical items makes me think it's a ground
problem but I am do not have a clue as to what type of setup you are
running over there. Did you try a surge protector?Is it 110volts with a seperate ground wire? Have you tried running a UPS?
is it the car vibrating or the sub making the noise ? if its the sub making the noise check all the screws holding in the sub and make sure they are tight or make sure nothing got sucked into your box if it is the car making the noise try using dyna mat to help stop the noise also check the surround on the sub and make sure there is no seperation of the surround from the cone
The amplifier in the sub as with any other amplifier has a capacitor in it. Essentially a battery that holds a charge. When you trun things off such as subs or amps with a powerstrip instead of the intended on off button, the power supply has been cut, but the capacitor is still energizing the unit. So it catches the noise in the line.
You need to check your ground connection. If there is a bad ground there will be feedback to the amp and it will just sit there and loop back with the Thump, Thump, Thump sound. I had to wire my amp's ground all the way back to the negative battery terminal. It was a pain but I have never had a problem since :)
hai iam hans i had also a problem with the sub
turned out jamo denmark didnt had the spare parts to fix it?
can u believe that
so i wait 6 weeks and after 100 phone calls to denmark and my local dealer they deside to take the part out of another sub ?.
but i really had to make a a lot of effort to achive this
but for the price the jamo set is exellent
a shame about the service .
