Hey, I was listening to music and my JBL II (2.1) speakers stopped working all of a sudden (they didn't make any special noise before they went dead), and their lights went off. The light on the Sub-woofer is on, however. I tried unplugging and replugging all power cables from and to the system, and all of the related computer cables. Also tried restarting the computer. Nothing seems to work. I've read on a similar thread that it might be the fuse blown out or the amp overheated. How can I find out what's the problem, and how do I fix it? Thanks in advance.
