Fp2 turn off and on continously

My fp2 turns off and on continuously. The resolution of the screen is blurred in pink tones to finish in a background of black and vertical stripes.
I have changed the battery and restored the factory settings, but the phone continues to show the same problems. Is my fp2 dead?
Is it a failure of the main chip of the phone?
There is a solution for this problem.


thanks i will try it, but why the fp2 turns off and on continuously? What can i do?

You can try to put some cardboard in the battery compartment to press the battery firmly to the contacts.
