My phone coolpad note 3 lite is not switching on but led light is on when I have plugged in charge how to solve this problem c

Sounds like the phone is on, just the display isn't. It could be something is loose inside or it could need a new display. If it is under warranty, contact the manufacturer. If it isn't, then I would try a local tech.
 


Did you resolve it?
I too had the same issue.Can u help me out resolving it?
