Pressing the power button multiple times (3-8 times) and then pressing and holding for 10 seconds might help you turn off your JBL Xtreme 3.<\/p><\/div>\n
If this fix works for you, you should be aware that it\u2019s not actually a fix.<\/b> This might be an indication that the button board, particularly the power button on it, needs cleaning. But this is a good thing. Nothing is broken \u2013 you just have to open the speaker, remove the rubber cover with all the buttons, and clean the button board beneath it with isopropyl alcohol. <\/span><\/p>\nThe other option is that there’s something wrong with the button board (or the PCB), like a damaged or broken power button on it. This can\u2019t be fixed with cleaning. You could try to somehow glue the broken part or replace the entire button board. <\/span><\/p>\nOne thing is certain \u2013 if pressing the POWER button multiple times helps you turn off your JBL Xtreme 3, your issue is most probably hardware-related.<\/b> So, you can\u2019t fix it by resetting the speaker or updating the firmware. You have to locate the exact source of the problem and deal with it. You may just have to clean the button board, but you may also have to replace it.<\/span><\/p>\nT<\/b>he Button Might Be Damaged or Dirty<\/b><\/h3>\n
I\u2019m not sure if this is the best course of action since we still haven\u2019t tried all the fixes that don\u2019t require you to open the speaker. If you are still not sure that the problem is hardware-related, you should first try other fixes that don\u2019t require you to open the speaker. Then, if other troubleshooting steps don\u2019t help, return to this one.<\/span><\/p>\nI\u2019m about to suggest that you open the speaker and clean the entire button board<\/b>. Why? Because when I say the button is clogged with dirt or damaged, I\u2019m not referring to those symbols you see on the outside. <\/span>I\u2019m actually talking about the contact pads on the button board inside the speaker<\/b>. <\/span><\/p>\nNote:<\/b> If your speaker is under warranty, DO NOT try to open it. You can try to reset or update the speaker, press different button combos, or press the POWER button multiple times, but DO NOT open it. This will void the warranty. Instead of opening the speaker, contact the manufacturer and ask for assistance.<\/div><\/div><\/span><\/p>\nI have already mentioned the button board so many times. It\u2019s finally time to find out what it is and what it looks like. The button board is located right beneath the control buttons. It connects to the PCB and sends electrical signals to the PCB when you press the buttons. <\/span><\/p>\nJBL Xtreme 3 Button Board (Source \u2013 JBL Xtreme 3 Service Manual)<\/p><\/div>\n
If the POWER button contact pad on the button board gets dirty (and there has to be some accumulated dirt over time), the pad will not react when you press the POWER button<\/b>. Consequently, the button board will not send the signal to the PCB, and the speaker will refuse to turn off or on.<\/span><\/p>\nCleaning the contact pads with isopropyl alcohol might fix the issue.<\/b> I\u2019m not sure if this is an appropriate analogy, but I did exactly the same thing with my parents’ TV remote. They also had a problem with the POWER button \u2013 it was unresponsive. I opened the remote and used a cotton swab and isopropyl alcohol to clean the entire board and all the contacts. When I reassembled the remote, it worked flawlessly. The POWER button was responsive again. <\/span><\/p>\nTo get to the button board, you have to remove the speaker\u2019s jacket, and then remove the protective rubber flap. There\u2019s no need to remove other parts if you only want to clean the button board. <\/span><\/p>\nFirst, you need to remove the jacket.<\/p><\/div>\n
Use a pry tool or a flathead screwdriver to remove the silicone flap and get to the button PCB.<\/span><\/p>\nRemove the silicone flap to get to the button board.<\/p><\/div>\n
You have finally reached the button board. Before cleaning the contacts, disconnect the flat ribbon cable connecting the button board to the PCB.<\/span><\/p>\nConsider disconnecting the flat cable that connects the button board to the PCB.<\/p><\/div>\n
Now, the only thing left to do is clean the contact pads. Pay special attention to the POWER button. <\/span><\/p>\nCheck the contact pads for damage. If they all seem fine, clean the contact pads using a cotton swab and isopropyl alcohol. <\/p><\/div>\n
If you notice that the POWER button is damaged or broken, cleaning it will not make a difference<\/b>. You could try to find the broken part and glue it back on, but I\u2019m not sure if this is going to be a permanent fix. It would be smarter to search for spare parts on eBay, find a functional button board, and replace your button board with the spare one.<\/span><\/p>\nReset Your JBL Xtreme 3<\/b><\/h3>\n
Every electronic device runs on some kind of firmware, and every firmware is susceptible to firmware glitches and bugs. Your JBL Xtreme 3 is not an exception. <\/span><\/p>\nThe standard steps to remove bugs and glitches include disconnecting the speaker from your device, forgetting the speaker from the list of paired devices, <\/b>resetting the speaker<\/b><\/a>, and updating the speaker.<\/b><\/p>\nHere\u2019s what you need to do:<\/span><\/p>\nFirst, unpair the speaker from your phone. <\/span><\/p>\nThen, forget JBL Xtreme 3 from the list of paired devices on your phone.<\/span><\/p>\nNow, assuming the speaker is turned on and you can\u2019t turn it off, <\/span>press and hold the VOL UP and PLAY buttons simultaneously until your JBL Xtreme 3 turns off<\/b> and you hear the power-off sound. <\/span><\/p>\nThen, if you manage to reset it, try to turn it on. If it works, your job is done! The speaker is fixed! To be sure, try turning it off once again. <\/span><\/p>\nPress the PLAY and VOL UP buttons until the speaker turns off to reset JBL Xtreme 3. <\/p><\/div>\n
Another potential fix, if resetting doesn\u2019t help, is <\/span>pressing and holding the VOL UP, VOL DOWN, and PLAY buttons simultaneously<\/b>
