Hey, It all started with updating my S3, after that everything went wel, but one day my screen is started to fading away .. Peace by peace .. I could use it, but didn't saw anything. After a few days, it went just black and didn't start. I ordered a new screen , replaced it ( not the first time done that ) . But it doesn't start. Tried to hold the 3 buttons, volume up and down to. Don't connect to pc, no reaction at all. Help !
