Question about Logitech X-540 Computer Speakers

Suspected blown fuse somewhere but no sign of it

Hey guys!

I brought some Logitech x540 speakers home with me to Australia (240V outlets) from the States (110V) and plugged them in before realising that I should have plugged them in through a transformer first. I heard a buzz then nothing and now even with the right transformer they won't turn on.

I took it apart to see if I could just replace the fuse but after taking the thing apart the fuse appears to be intact.

Nothing appears to be burnt out or anything so i can't see what is going wrong. Could the internal transformer be blown?

It would be great if someone could give me some assistance! :)

    Oh, actually there is white liquid on the tops of some of the capacitors, I think its all blown :( just too much voltage, but why didn't the fuse go off? Is it because of the different current?

    Oh good, that makes sense. So if the transformer blew and the fuse on the chipset didn't would the chipset still be intact? Is the thin white substance on some of the capacitors on the chipset normal?

Am sure that the internal transformer is gone, You would have powered your speaker with a step up/step down transformer, you need to see a technician around you that can help you out, you need to replace a 220V-230V transformer in the speaker since your country requires that.

In electronics, don't believe, be sure. When it does not say AC, see what is next to it. The ~ sign means AC. The = sign means DC. I know lots of speaker systems use AC, but check the sign.

The mains transformer in my Logitech x540 has blown (oc on the primary). I've taken it out and its a simple single coil primary and secondary, but there are no markings on it to indicate the secondary...


You would need to rewind the coils.Do not try to do it by yourself if you have no idea what you are up-to...this time it was transformer next time it could it could be your circuit.Take it to a professional,the charges won't be much.
Good Luck.

I accidentally connected VS4121 speakers to 240V instead of 120 V


Hey i am also from india. Every speaker unit has a built in fuse unit which protects it from the over voltage. just replace that with a new fuse of same rating. if you are not sure of what rating the fuse is, consult with the electrical shops. and then ask them to give a 240v to 110 or 120v AC to AC dimmer. just use this with your speakers and they will run with no problem. but if it is a serious damage inside then you need to take it to a service center.
