I have the same problem,: - my jbl charge 2 is fully charged - I switch it on without problem and lights of Power button and sounds level are all ON => it doesn't make any "beep" sounds when it turns on as before - I have no problem to pair it with my iPhone, it is recognized by Airplay => I do not get any sound when I play music on my Smartphone => I do not get any sound if I connect using a stereo audio cable connected to the 3.5mm aux input as per jayeff question I have opened the casing but do not see any special damaged items in it... do I have to change the speakers? Do I have to change the electronic card? Any suggestions or guidelines ? Thanks for your prompt response and advises.
