USB Speakers (READ ONLY ARCHIVE)

[Mikulcak]

Hi everybody,

a few days ago, my Z-10 simply stopped working. When I plug in the power cable, only the display is lit, the buttons are not, my MacBook (and a Windows PC, too) doesn't recognize the speakers via USB, they don't amplify audio that is connected via the AUX-port. 

I'm quite sure they broken beyond repair, but maybe someone had the same problem once and found a miraculous solution...

Thanks in advance,

Marcus 

P.S.: The Windows machine is running XP, the Mac one is running Snow Leopard.

Hi,

Try unplugging them, waiting 2 minutes and plugging them in again.

The display will not work on the Mac. The LCD software is for Windows only.

[Mikulcak]

Yeah, I know, it only shows the Logitech logo when you connect them to a Mac, but they don't show that anymore, too. The display is only lit, nothing more. And unplugging unfortunately doesn't help, they always fall back into the same state when I plug them in again.

I'm just wondering if you found a solution to this problem? I seem to have exactly the same problem.

Firstly my speakers started to crackle loudly, then Vista detected an nnrecognised USB item under the universal serial bus controllers section of device manager. Following advice from other threads I unconnected the USB cable and the power, waited about 30 minutes, turned the power pack on and reconnected the USB cable. Vista re-detected my speakers and everything was fine again.

A few days later I get the loud crackling again, and power off the speakers. Now when I turn them on again only the LCD display lights up, non of the buttons, and I can't power them off again from the front controls. I get no audio from the speakers, and I've checked all the connections. I've also checked my sound card is outputting sound using an old pair of speakers.

Any help anyone can share would be great, I'd be suprised if these speakers only had a 2-3 year lifetime since Logitech's products are usually quite solid.

Kind Regards,

Paul

Yeah, same story here, when I connected them a few days later, loud crackling, nothing more. Since your speakers behave exactly in the same way, it must be some kind of a common, or at least not totally random failure. But well, It's sad - I didn't find a solution, the two year warranty is over, too and it looks like I have to say goodbye to them.

Sorry I couldn't help you,

Marcus

Hi,

Could you try using a different USB cable?

[Z10Problem]

Sadly I can't try using a different USB cable since I don't have another - although when I turn the speakers on at the moment (without the USB cable plugged into the computer) only the LCD display lights up, non of the buttons do, and non of the buttons work and I get no sound at all. I can't even switch the speakers off using the button on the front, the only thing I can do is turn them off at the mains.

[Z10Problem]

Ok, managed to find a spare micro USB cable to try as you advised Mike.

Connected the USB cable from my camera to the PC and speakers, powered on the speakers at the mains. The speakers came on, well the LCD backlight glows up, nothing else. Windows redetected the speakers as an unrecognised USB device. I still cannot press any buttons on the speakers, or recieve any sound output from them.

Turned them off again at the mains, waited 30 mins, disconnected the micro USB cable, and turned the speakers back on again. Same as above. It seems the speakers won't fully 'boot' up at all.

Hi,

Looks like the Z-20's are defective. If you are still under warranty please contact Technical Support for a replacement.

[Z10Problem]

Yeah, sadly there 3 months outside of the 2 year warranty :/

Thanks anyway for you help.
