I have a CDP-C77ES 5 disc CD Player. When I opened the tray it looked like there was a white powder all over the tray. I went to clean it off and realized the plastic is soft. What looked like a white powder was really just the texture of the plastic that seems to be deteriorating and getting soft. You can dig into it with your finger nail. I thought I had seen everything, but this is a new one. Here is a link to a photo of it.
You can see on the right where I tried to clean it, but I was really just flattening out the soft texture of the surface. You can also see a couple areas where I just touched the surface and left a darker fingerprint where the texture gets flattened out. Anybody know what might have caused this? I had purchased it at an estate sale, and it tested just fine. I then stored it in the attic for a month, and I'm just trying to use it now. The attic goes down to around 45 degrees, but that shouldn't cause a chemical reaction. The closest thing I've seen to this is when the rubber pinch roller on a tape deck suddenly deteriorates into a soft goo.
