My xbox 360 will no longer read any game or DVD discs. I'll put a disc into the xbox, on screen will show that the xbox is "reading" the disc, then it will change to "open tray". I know these discs are fine because they have been used plenty of times before. This didn't start happening until the day that i downloaded the latest dashboard update. Any suggestions on help or what to do will be much appreciated.
Things that I've tried to fix the situation:
-try using mutilple "clean" dics -removed the update/then re-downloaded it -clearing system cache -went through the "official trouble shooter" -support chat with an ambassador
