Thank you for your reply.
If none of the previous solutions works (the most important troubleshooting steps), I have good and bad news for you (please don't shoot the messenger).
Bad news is that your Kindle is defective. I have provided you with the all troubleshooting steps for resolving this kind of issue (resetting the software, force reset, USB charging). Unfortunately there is an hardware issue on the device that software troubleshooting can't resolve.
Good news is that if your Kindle is still under Amazon warranty (1-year warranty) you will receive a new Kindle for free.
If your Kindle is out of warranty, the good news is that Amazon does often replace Kindles out of warranty. At least they would replace it for less than the cost of repairing.
You will have to contact your seller or Amazon warranty support service directly to arrange replacement.
There is an option that Amazon calls you. Please follow the steps below:
1. Go to the page below - click here
Log in using your Amazon account information.
2. Select Kindle > Kindle Device (or Troubleshooting my Kindle) > Problem with my Kindle > My Kindle is damaged or Kindle is frozen/unresponsive
3. Click Phone - Call us
4. Enter your number and choice "Call me now" or "Call me for 5 minutes".
Sorry because your issue is not resolved, but there is a hardware issue that can't be resolved online.
If you need more information or help please don't hesitate to ask.
