CX CAS freezes in the black with white lines screen

Hello, I need your help. Yesterday I had to reset the handheld with the button but when it boot again the CX CAS didn't pass through the black with white screen.
I have tried the 4 possible formats but it keeps freezing in the same place.
Anybody knows something?
