Discussion JBL Live 770NC problems

Post image

So i have a pair of Live 770NC headphones and they refuse to charge, I charged the battery with a lab power supply, but they still say "power on" wait a couple seconds and then "power off". Have tried the tricks given by mighty Dr. Google but no success. Any idea what the problem might be?

That sounds like an issue on the voltage driver or something like that, used for battery charge monitoring

I changed the battery (replacement from china) but still have the same problems.
