Since couple of days ago, my speakers keeps turning off. The green light just shuts down. To get them to work, I got to play with the node until it's stable. Are my speakers finished? How can I correct it? Thanks.

are they usb speakers.
mayby the usb connection is dodgy

No there not usb.

Well then what kind of speakers are they?! A little more detail might be helpful. If the speakers are bad then there is not much you can do other then replace them or find someone who knows enough about electronics to repair them.

Did you try the speakers with something else? (Like plugging them into a walkman or discman)
