INTRO (feel free to skip)\nMy lucky streak ended abruptly. After selling a mountain of old gear, a buyer finally asked for my CD player. It's Sony XA5ES. I've been selling it for a long time and was very happy to finally find someone. And he was a cert. He said if it looks like in the pics, he's making a reservation (and it does, it's very well kept).\n\nAfter bringing it in from my family house, I noticed it fails to open the tray every now and then. (And do I hate these "every now and then" problems!! For crying out loud, is it broken or not...?) I had to call it off, I had no heart or peace of mind selling a unit in that state. I won't do it.\n\nPROBLEM\nThe tray will sometime open and sometime not. There's no rule. What I did to check my first suspicion was to see if it has to do with loading the CD. When you put a CD in your player it spins and gets read for the info on the number of the songs and the overall length. I thought perhaps you can't interrupt this process and it doesn't want to eject the CD while it reads it. But it's not that.\n\nThe only thing I noticed that it will happen more often after playing a CD and less often if you just keep pressing the open\/close button. But it's never 100%. Every now and then it doesn't open.\n\nDo you know what could be the usual suspects? What to check first? Everything else works.
