Galaxy Note 2 gone white with grey stripes

Hi
Why is the screen on my Galaxy Note 2 gone white with grey stripes across all over the screen?
I have just got a problem with my Galaxy note 2 phone. First the screen suddenly become black, only the phone's logo appears. Second, the screen became white with grey stripes across the screen. I have tried with an identical battery, but it is the same. I have tried with an identical battery, but it is the same. After the last attempt on a solution I did a hard reset, but only the following screen appear: Warning!! A custom OS can cause critical problems in phone and installed applications. If you want to download a custom OS, press the volume up key. Otherwise, press the volume down key to cancel. Volume up: Continue Volume down: Cancel (restart phone). After pulling the volume down, nothing happend except from the same screen pop up again. If I choose volum up key, the following appears: ODIN MODE, PRODUCT NAME: GT-N7105, CUSTOM BINARY DOWNLOAD: No, CURRENT BINARY: Samsung Official, SYSTEM STATUS: Custom, KNOX WARRANTY VOID: 0
RP SWREV: Well, I can’t come any further no matter if I choose the volume up or down, so my question is what the heck I’m suposed to do now?

Please help this lost guy
