My GT-N7000 phone fell onto the for from sofa

My phone fell onto the floor from the arm of my sofa. Onto carpet so wasn't a bad fall. At first it wouldn't turn on then when it was on charge it only showed it was charging and now it will load up with samsung and then repeats that over and over won't load to the home screen. I've had it on and of charge for periods of time but it won't turn on fully please help.
