Hello my name is***** look forward to assisting and am very sorry to hear that you are having this problem.
I want to warn you that it is possible you will need to replace a part in order to fix this.
There are a few different things that can cause this and a couple different parts so we would need to troubleshoot to find out for sure.
Even if it does not look like it is charging and even though it may be fully charged charge it using a different wall outlet than you normally do (a different room is best) for at least 10 minutes.
Do not skip that even if it is fully charged from you already plugging it in, it is important to do it.
It sounds like the firmware may be frozen try this and let me know the results hold the power switch for at least 60 seconds.
Try this at least 6 times.
The firmware can sometimes get frozen the same way that a computer will occasionally.
If this did not work please come back and let me know by clicking on reply to expert so we can continue.
If it did work please don’t forget to leave a positive rating it is greatly appreciated.
