Why is my phone screen blank and blinking?

If the screen remains blank but there is still a light that keeps blinking, then that light might be blinking an “error code”. Error codes are installed in electronic devices by the manufacturer for troubleshooting purposes. Each code indicates a different problem with the device.

Take note of how many time the light blinks in a row, and do a Google search for that error code. Include the make and model of your phone in the search. Google.com is really good at including search results for error codes of electronic devices.
