JBL Flip 4 is not powering on when not plugged in
I have a JBL Flip 4 and since yesterday is randomly turns itself on and right off again. Now it turns on when I plug it in and the battery light show, but then it shuts down again. The speakers and bass are working fine. If I unplug it, it shuts down immediately. I can’t turn it on without it being plugged in. I already tried the connect+ and volume up method and that didn't work.
Thanks in advance!
