Try charging the phone for 1 hour and then reconnecting to itunes, i'd also check that the charging port is clear of gunk too. This may be that the battery is dead or the dock is the problem..if the battery is dead it will not supply enough power to wake the phone when connected to the pc. (the pc only supplies enough power to do small tasks once the phone is on) If the phone vibrates after being on wall charger for a few minutes then it sounds like a battery problem. Charge it and see what happens, if still nothing then I'd replace the battery and the LCD screen and possibly the dock. If you replace the LCD then maybe you can see what's going on...
