So, I have my wife's iPhone that we recently bought used online. It was working for about a week or so and yesterday was starting to not respond. She would press the home button, or the sleep/wake button, and the phone would not turn on. This morning, it will not respond at all. I try to do a hard reset with the home and sleep/wake button. It will flash the white screen and black Apple logo, but then go to the unlock screen. The unlock screen is dim and the touch screen does not respond so we are not able to get the phone to unlock. I have tried pressing and holding down the sleep/wake button and I get the slide to turn off, but the touch for the slide does not work. I plugged the phone into a couple power sources and tried two different cables and power bricks, one for iPhone and one for iPad, no response. When I do see the screen, it says 90% or so. I am thinking of opening the thing and disconnecting the battery for a few minutes to rest it that way. I've tried to put it into DMF mode by holding the home button and connecting to my MacBook Air, but iTunes just says that the phone is locked with a passcode and unlock the phone first. Well, the screen does not respond to touch so I can't unlock the passcode. . . . Have you seen anything like this?
