Hey guys,

I have just got back home and after turning my computer back on from the wall I heard a loud bang and now my speakers are just lifeless. Nothing is responding when trying to switch them from the remote.

These speakers are about 3 years old and I'm hoping they are still under warranty :(

It doesnt show anything on overclockers website.
 
Okay thanks buddy :)
Will give it a try and hopefully it works for me!
I was only gone for 4 days, everything was turned off from the wall and when I switched it on the bang was loud.
 
Phal you probably will be right. It surely did sound like it would be something else. On the corsair forums, people have had the same issue as me and opened up the subwoofer and the PCB was damaged/blown
 
I always check the obvious first,nothing to lose in doing that.

Are there any trip switches on the circuit,they can make a pop when they go?
 
That's very true, I will be checking the fuses once I finish work and hopefully I can bring them back out to life without forking out another £200 haha.
I don't think there are any trip switches, I've tried changing plug socket but still nothing.
There's no way checking if there is actual power as to turn them on its by the remote. The remote could have broken? Who knows
 
Definitely worth checking the fuse but I wouldn't hold out too much hope.

Some kind of crack or pop is usually some kind of component/s which has/have blown like a capacitor or something.

You could try checking the innards for any components that are obviously burnt/discoloured/bulging etc but then you'd still need to get that part replaced and hope that it's the only part with an issue.
 
I am pretty much expecting the worst because on the corsair forums people experienced this exact problem and it resulted in the circuit being badly damaged.
I will open her up when I'm back and see what has happened.
For the time being I have requested an rma at corsair and hopefully they can help me out. Warranty was only for 2 years which I find pretty poor for £200 "premium" speakers. They only lasted me 4 years (will be 4 years in 3 weeks). Again i think that is poor for speakers.
 
I was fairly lucky with my old Razer Mako 2.1 speakers. They lasted 6 years and when they did go pop, it was a part known to be a common fault so it was a fix even my limited soldering skills could replace. They lasted another year before dying in a different manner lol
 
It's horrible when you really enjoy something and then it brakes :(
Well I've opened her up and the fuse has gone but the capacitors are damaged too. Some are bent and there's this very strange red/brown solid goo which looks like it's seeped from the damaged capacitors. Something like this image http://i.imgur.com/n2XYclD.jpg?1
 
That goo is there from the factory. (some form of mastick designed to prevent vibration and movement) The problem looks like it is concentrated around the TO-220 IC mounted to the aluminium sink on the left side along with the two resistors. (see the black charring on the PCB itself and on the heat sink) The glass fuse on the left looks like it is still ok, so the bang is likely to have been the transistor/diode going bang in style.
 
That image was only an example but you have helped what I should be looking for and when looking at mine I can't see any kind of black charring. But my fuse has gone because its all liquid crystal looking and no wire.
I'm going to buy a new fuse tomorrow and just see how it goes.

Not sure how to upload a picture on here
 
I think it might have Beene only the fuse which has gone but now a small problem is that when I removed the fuse one of the fuse legs came off. It was very loose to begin with when removing it.
I was told by someone not to risk placing a new fuse there? Any advise?
How annoying that one fuse leg came off!
