The screen lights up but blank white, it won't do anything including switching off

Hello,

The first thing to check weather your phone is working fine is by plugging your iphone to a computer using you usb cable.

* If the phone have been detected in normal way when itunes comes out and give complete details and information of your phone,it seems your phone LCD screen has the problem,it somehow need replacement.(bringing it to apple center is the solution for parts replacement.)

* But if then phone have been detected as recovey mode,your phone firmware seems to have problem,by somehow fixing this basically,try to press and hold POWER + HOME button simultaneously for about 20-30,then see if the phone sets to normal.

If not,then you need to restore the phone by following this procedure : FOLLOW ME

If you have some concerns,please let me know and i get back to you as soon as possible.
