Cut to the chase...my Evo died on me. Fully charged. Took it off the charger and pressed the power button to bring up the unlock screen and nothing. I put it back on the charger and there was no light. I took it to Sprint and they gave me a "new" phone. I realized it was refurbished when I saw that it was already updated. Now the "new" phone has an issue. When I press the power button to get the unlock screen, I only see the "buttons" on the bottom light up (the home key, back, etc). The screen remains black. I power it down and try to restart it and the same thing happens. I left it alone and came back to press it and then the unlock screen comes up. This has happened 3x already. My phone is not rooted. And I have a 64g sd card that only stores pics, music, and some docs. Please help!
