Usually this is the case. The LEDs will flash while it is charging and then turn off when it is done. Odd behavior, I know. Especially while it’s connected to a power supply. To check the battery level, press the volume up or down button while it’s not charging or playing music. The row of LEDs will light up momentarily, corresponding to the battery level. There’s also a phone app from JBL that will give you more information and control over your speaker. Hope this helps!

This is a slight edit considering I browsed through my old answer and even I found it a little confusing: I had a logic board accident with my early 2011 MBP, model a1286 and was thinking of replacing it with a Mid-2012 (non-Retina) board for the CPU/GPU boost (I'm a gamer and a Mac user... figure that one out) and the upgrade from USB 2 to USB 3 ports. I found a decent deal online but I couldn’t find anyone who ever tried it. The iFixit teardowns and logic board replacement guides for both models (2011/2012) seem identical along with all of the tech specs about the wattage/voltage/etc. I heard from a repair shop guy on e-bay who said the upgrade wouldn't work (but I think he was just trying to sell me his repair services). I was actually amazed that there wasn’t more information about this kind of thing on the internet (with all the menial stuff like hacking your xbox and tricking out your iphone). For the life of me, I can't see why this 'upgrade' wouldn't work, and the iFix it forums have instilled some...

Ok, so it shows it’s fully charged on the PS4 but the light on the controller is out if I’m reading you right. Method I would use… connect the controller to your computer with a wired cable (eliminating the PS4 from the equation).

Check Device Manager in Windows or System Report on a Mac. Does it show your controller?

Yes = USB port on controller is fine, you may have damaged the LED on it during the repair.

No = USB port may be damaged or the cable may be fried.

Your problem doesn’t seem like it would have anything to do with the USB port. If it works but with no lighting, you should be ok unless you use the controller with the PS4 camera.

Anything can be fixed. But without knowing how severe the damage is it’s hard to say how difficult it would be, although it may involve cannibalizing another controller. At this point it may be cheaper to just purchase a new Dual Shock.
