Does the Kindle still power on?
Okay, did you get the new cable and charger?
Try these steps please.
Press and hold the power button for 40 seconds then release.
After the Kindle reboots, wait about one minute the power off.
Then clean the charge port with rubbing alcohol using a small brush(tooth brush etc...) Blow the port out with canned air if you have it. Then when the port is dry power on and try the charger again.
Let me know if this does not work and we can try another solution.
