Question about Harman Kardon SoundSticks II Computer Speakers
Many topics on this of course, but the buzzing from the sub is frighteningly loud. Usually rotating the 3.5mm plug on the computer works, but recently its almost impossible to stop it. More scary is that when trying to plug it in the back of my new iMac and my hand touches the back of it I can feel what I can only describe as 'power" running through it and into me. Like a bad earth or something? Any advice?

Hi, probably two things that can go dead, 1) the woofer itself and/or 2) the amplifier. I will rule out poser supply cos the other speakers are working. Normally they have a separate amplifier than that of the woofer. If you are comfortable working with a soldering iron and a multi tester, after unplugging from the mains, then you open the enclosure and check the continuity of woofer which should read between 4-8 ohms, if it is open or no reading, replace just 2 wires/terminals involve with 3 or 4 screws. If the woofer reads a continuity, then it is the amp which normally is just a single power IC attached to an aluminum heatsink. In some instances, it may be a power transistor pair. In any case you have to be familiar with component level repair. Otherwise, you are probably better off asking a qualified service personnel to do the repair job. Hope this be of some help. Pls post how things turn up. Regards.

My problem is fixed now. I plugged the speakers into the earphone socket. There was no immediate effect just silence. I twiddled the control on the bass unit, played with the volume controls on the sticks. Then I realised the sound was back with the external speakers not the internal ones. It was as though the Harman Kardon system was re-booting itself. Very weird.

speaker amplifier chip may leaky or damage
you are using improper sound driver
check driver status in your computer device manager or just typing dxdiag on run in start menu, check status of sound driver installation
