ive been given an xbox to look at were the dvd drive is stuck and wont move. the tray its self sticks open about an inch and can be pulled out a bit more and back in again. the console goes to the dash fine but the centre light just flashes green it looks to me like someone has tried flashing it and messed up? i dont know any history of the console which is anoying but whoever had tried to open it up before me was a compleate amature and had butcherd the case close to death. which leads me to think its the same amature tried to flash it and screwed it up the drive is a lite-on 83850c any one got any ideas?
