Screen doesn't turn on

[jamesfrom818]

So my Touch Pro recently started acting up on me. I pulled it out of my pocket last night and the screen wouldn't turn on. I could tell it was on because the backlight and the other lights would turn on and off when I press the power button. I've never dropped my phone so I figured it was a software problem so I flashed to a couple other ROMs. It works for a few hours and then the same problem arises.

I'm guessing I'm going to have to return it. So, other than flashing back to the stock ROM, is there anything else I have to do to prep it for a return to Sprint?
