There are a couple of issues. A couple times I have looked at this issue it ended up being that one or both of the screws on the power button retaining bracket were not installed. Does the button make clear clicks when depressed? It shouldn't be hard.

Check your cables for folds, tears or rips. Check the port the cable plugs into for dust, debris, or broken solder points. Is this phone still recognized by iTunes?
