Kindle paperwhite 7th generation won't power on

kindle will connect to computer. Can load books with USB. Even updated the kindle but won’t power on to read on kindle. The screen flashes from the tree screen to blank screen and power light goes back and forth from amber to green. The blank screen will flash twice and then go back to tree screen. Is there any hope of getting it repaired? If on charger it will keep flashing back and forth from blank screen to tree screen.
