Worked fine until today and now one of the speaker's subs will not turn on. Tried changing power cords and even the outlet it was plugged in. Fuse looks fine. Any ideas?

One idea is to contact GET support.

Does the blue light come on and flash the same number of times as the speaker that is working?

Correct, or better yet, your local dealer, to speed the process of diagnosis and repair. (If LED is not illuminated, triple check to make sure the outlet is live, the power cord is fully seated, and the fuse is good before doing so.)

The Green light on the working speaker's subwoofer is lit. On the one that is not working it is not lit at all. Do you know what kind of fuse it is? I may double check it even though it looks good.

If you can't test the fuse with an ohmmeter, than just swap the fuse from the working speaker to test. (The fuse spec is on the back panel, in the owners manual, and on our website.)

If it's not the fuse, jot down the serial number and call your dealer. Give him a description of the problem (no light, no output) and the serial number and they can get the ball rolling on getting service parts on the way to them, to repair the failed speaker.
