About a week ago I went into Goodwill and saw a Marantz CC3000 5 disk CD player for $10.50. I debated and debated and let it go. When talking to my dad a day or two ago, he expressed interest in the CD player, so I ended up going today and purchasing it. I was able to semi-test it, finding a socket and plugging it in and doing what I could without a cd in hand.

Now that I got it home, I realize why it was donated. It wont read the CD's. Ive tried numerous times to no avail. Took it apart and didn't see any blown caps or anything wrong with the board. I cleaned the lens and tested it again. Still nothing.

Does anyone have any idea how to troubleshoot this?
