I received a broken CDP-CX400 from a friend. Your problem sounds the same. One of the retreiving arms might be broken as mine was. It takes both arms to grab a cd and with one broken it will not load/play. Mine would spin and the light flashes but nothing else. I took the cover off and dissassembled the mechanism. Then epoxied and reheated the joint. It works now but the cd's can lean so it may happen again. I am not sure if you can get parts but Sony has a good website if you dig into it and you may be able to get the part. Your posting was from January so hopefully you received an answer already or receive this one. If you need more help let me know. If you want to get rid of it I could use a remote and keyboard. Good luck.
