My first guess is the filter capacitors in the output stage of your amplifier are history/worn out.Try a different amp to confirm.Otherwise disconnect the speaker wires and check that the impedance/ohms value is at or near the stated value,4 or 8 ohms.This measurement can be made with a cheap ten dollar VOM "volt/ohm/meter."

NO .

Your driver has a damaged voice coil, you can either find a speaker repairer to replace the voice coil or find a replacement driver to fit.

It could be a bad or bad capacitors. On the power board. Capacitors look like soda cans small soda cans. Good ones will have a flat top. Bad ones will have a biging top and sometimes fuilid sedimant leaking from them..

Hi,
Just get it here:

WE REPAIR THESE AMPS - EBAY - EDWARDS ELECTRONICS - :)

Sound like the tweeter is blown, take to local jbl agent for service.

Switch the speakers over just to make certain it's not the amp. If still bad on the good channel, then the crossover (inside) might have developed a fault.

Has nothing to do with the signal or source - it is a failure of the turn on circuit - I repair this amp - can help if you find my add here or I am located on ebay as well. Juust do a search for We Repair JBL and find the model :)
