JBL Go3 turning OFF automatically | Not charging.

A friend of mine bought a refurbished JBL Go3 bluetooth speaker online and this speaker started giving problem after few days, the problem was it was switching off by itself after few seconds, the charging indicator LED light was glowing whenever charger is connected but the battery was not charging, this video shows how to solve this problem.
Take care and do the reparation on your own risk.
Thank you for watching, have a GOODTIME....
