Screen died

[cccpms6]

So the trouble started a week ago, the keyboard would work in and out. Like I would be typing than it would stop working I switch to the touchscreen one and after a little open it up again and it work fine.
So today the screen just goes blank. The phone started being slow so I just hit the power button to turn off the screen, but when i tried bringing it up it stays black. the touchscreen works cause it recognizes pressure. but it won't show anything. I've tried everything but it still stays black. Basically the backlight is on but its a black screen.
