Charge 3

Here we have a JBL Charge 3 speaker where the first LED continues to blink while charging including the additional problem of the buttons to not work.

I have found that if you open the speaker up to where you can get the battery connector, you can probe the input power pins from the battery.

You do not get voltage when the battery is plugged in, yet the battery reads voltage when unplugged from the board.

I took the main board out and noticed the positive and negative pins for the battery on the board connector have continuity. Hence, a short to ground.

To be sure it was the main board, I unplugged each sister board one by one to see if the short disappears. Nope!

So the main board will need to be repaired since there is a short to gnd. I did notice some caps near the input were shorted as well around the IC chips too. Most likely one of the IC's are bad. My diagnostic skills end here, I wouldn't know which ic chip it is since there's shorts around each chip.

If anyone can add to this please do I'd love to know what steps to take next!
