My JBL Charge 1 had a similar issue. I was able to turn it off no problem, but it kept turning on buy itself randomly.
So I opened it up, unplugged the three power cables and plugged them back in. Also used a lens blower all over to remove any dust. Don't know if that did anything, but it's now fixed.
It takes some patience, because there's glue everywhere and the parts are tiny.
I'm no expert. It was a shot in the dark really, so I guess I just got lucky.
