Ok, I just got this cdp used. At first it worked perfectly ( and is in near perfect condition) then after about ten days it would not recognize that a cd was loaded. A member at av123 said he had switched out this part
http://www.mcmelectronics.com/product/32-18255. I'm not much of a do it yourselfer audio wise and I thought I was getting this

which I thought looked pretty simple. Four screws and a couple of wires to unplug. Easy peasy. But I got this

and I thought "Oh shit". This part is in here:

and there is lots of "stuff" to undo to get at it and 6 teeny tiny wires to unsolder and resolder. The bad news: 6 is the total number of solders I have done in my life. The good news: they all worked!.
Well too make a long story a bit shorter: Houston we have lift off! Yeah, baby I'm a geek! I'm nerd! It's working flawlessly. Yeah!

Had I known what I was getting into I wouldn't have tried it. The other thing, I can't remember who gave me the link to the part, but in retrospect I don't think he liked me...
