Just posting here for the sake of reporting another issue. My xbox slim is doing the exact same thing, green flashing light on start up and it says tray ''opening'' when its closed and when i open it, it says ''closing''. And also the tray never seems to stay open for more than a few seconds. (Never done that before, have caught and scratched a few disk because of this)
Funny thing is..........this only started happening after a thunderstorm knocked out our power which fried my router. (which is wired to the xbox) Could there be a connection here??
