There should be a short circuit inside its circuit board. You have to check the audio output circuit to get the fault, and to replace the damaged component/s. If you wish to get some details; check the site linked here. Pull up older posts. http://electronicshelponline.blogspot.com/

Circuit diagrams of SMPS & power amplifier to many models of JBL sets are given.
The power supply consists of two parts: the AC cord with a two-prong connector on one end and a double barrel plastic connector; and the large rectangular power supply which has a dual prong receptor on the side and a long cable which plugs into the JBL unit.
In my case, I had plugged the double barrel plastic connector into the dual prong receptor backwards. Even though I was getting full power to the unit, this somehow caused the speakers to become inoperative.
Of course, I would offer a recommendation to JBL that their power supplies are made to be "dummy proof" so this does not happen to others as well.
What you'll actually need in order to get Sirius is a satellite specific receiver (the JBL SIR 2.5 Satellite Receiver). That should come with the antenna you need.
