Do your JBL Flip 4 speaker’s buttons no longer work? Have the buttons stopped responding or stopped lighting up? JBL Flip 4 speakers are susceptible to a range of problems that could cause their buttons to stop working. Check the following possible causes to identify and solve the problem.
Cause 1: Button Housing Is Clogged By Debris
If one or more of your JBL Flip 4 speaker’s buttons are not working, it could be due to dust and debris stuck in the button housing. Use a can of compressed air to clear out the button housings, then try to use the buttons again.
Cause 2: Button Housing Is Damaged
If your speaker’s buttons continue to not work, the button’s membrane may have been damaged. Button failure can also occur from long-term use. Use the JBL Charge 3 Button Replacement Guide to replace any of the speaker’s buttons.
Cause 3: Faulty Circuit Board
Because the JBL Flip 4 is sealed very well, it is unlikely any debris would be blocking the buttons. The main cause for unresponsive buttons would be a faulty control board. To access the control board under the buttons, please refer to the JBL Flip 4 Controls Board Replacement Guide. Unlatch the wire that is connected to the circuit board, and then plug it back in. If the lights on the board do not flash, replace the circuit board. If the lights on the board flash, the speaker should be working again.
