Steps to troubleshoot and fix the issue:
- Check the power source. Is your phone charger plugged into a working outlet?If not, plug it into a different outlet. 
 - Is your phone battery completely discharged? Try plugging it into the charger and waiting a few minutes before turning your phone on. 
 - Try a different charging cord or wall adapter. If the cord and adapter you are using are not original, try using the original parts or other replacements.  
 - Make sure your device has enough memory to power on. If not, you may need to delete some files or applications. 
 - If the problem still persists, contact your manufacturer's customer service department for further assistance.
