I'm sorry about the issue. Have you tried this: Press and hold the Power on / off button on the kindle for about 30 seconds, then turn it back on and check.
- If needed, please charge the kindle for about 15 minutes, then while charging, press and hold the Power button for about 60 seconds this time, then turn it back on and check.
If that does not work, does it still show blank? How old is the kindle?
Please reply at the box below to continue troubleshooting. Thank you.
