So I know there are a lot of forums about this but I think my problem is a bit different. The phone itself works fine and the touch screen does too, it just doesn't turn on. I've had the phone for a while so I know how to navigate it without seeing anything, but not that well. I can still call using the slide out keyboard. I've tried turning it off and on, plugging it in, taking out the battery etc, and that weird turn your phone upside down and push the samsung logo (?) but I'm not sure I really understood that one.... Anyway, I have no idea what to do, like I said the screen works and responds if you touch it, its just black and doesn't light up like its not on but when I slide the keyboard out it, the keyboard lights up. This happened to my samsung flight a couple years ago as well... Please don't tell me to just send it in because thats not what I'm looking for but thanks in advance ..and pleeeeease help me, I'm desperate!
