Z5500 Subwoofer dead(with pics). How to repair?

rockstarsr · 28th September 2010, 01:20 PM

Recently couple of rats have invaded my house and one of them even dared to enter the subwoofer.
And here is the result:
ImageShack Album - 6 images

From then, ALL the satellites and control pad is working totally fine just like new ones...EXCEPT the subwoofer.

You can see the condition of the subwoofer in the pictures.
I took the subwoofer to the local repair shops(as the speakers are more than 2yrs old and hence out of warranty).
They replaced some of the damaged capacitors and wires..but none of the 4 repair shops to make the sub functional again

Now how can i repair the sub myself..? Or can anyone tell me any good repair shop in Bangalore(India) who can repair it without fail...

Cheers.

im3164q.jpg shows 1 unconnected red wire

Where does this go to and where should it be connected to?

When you say all the satellites are working do you mean they have sound and the only problem with this is that there is no sound from the woofer?

in img3165m.jpg i see on the right something that looks like 2 blown caps , very hard to make it out on the image. and two cut wires.?

was these before or after the repair shops "replaced" the caps?

but still no result

Can somebody tell me who can repair this in Bangalore...

Has the driver been replaced, too?

If that's gone open circuit, you won't get any output... Test it with another speaker or something.

Nope. Driver is not replaced. But since it is not 100% damaged, i was expecting atleast some minor noise from the sub to tell that the circuit is working...

Just give it to your friendly neighbourhood computerwalla.
Logitech is a common brand, they'll fix it up for you in a day.

I did that..and still sad results

I even gave it one of the biggest and most sophisticated electronic repair center...and they couldn't repair it! :!

If the voice coil itself isn't working, you could damage the amplifier trying to use it. A short circuit on the output will kill most amplifiers.

If the driver has gone open circuit, you won't get any noise out either.
