Can anyone help how to fix my led?
(lemm.ee)
For questions about component-level electronic circuits, tools and equipment.
1: Be nice.
2: Be on-topic (eg: Electronic, not electrical).
3: No commercial stuff, buying, selling or valuations.
4: Be safe.
There is like a multitude of possible reasons.
Can you open it up, without destroying or damaging it?
If so, you would need a multimeter to trace, which components are broken and maybe you can repair them.
After opening up, it might also be obvious what's the problem.
Most likely it's just a worn out micro usb port, which are usually super shitty.
