i was on my phone and all a sudden the screen went blue along with a high pitch sound then went black, i have not been able to turn it on since this happened
Welcome to Android Central! That sounds bad. I would suspect failure of the motherboard.
Try plugging the phone into a wall outlet and letting it charge undisturbed for at least 6 hours. Then press and hold Power for about 30 seconds. If nothing happens, then it's probably dead -- hopefully you were keeping your important data backed up or synced on a regular basis!
