Basically, the screen is all black, but when I do a hard reset, the logo doesn’t show up. However, the touch screen still works, and it still vibrates when it is being turned on. I have attempted every trick and fix I could find.
ForTheKaiser since you already tried everything that you could find and it still does not work, I suggest that you change the display. It is possible that your LCD screen has failed or this is a board level error. Since schematics are not readily available for your phone, you will have to start with a new display first.
