Sony CDP-7F

Hello

I recently won an epic Sony CDP-7F Midi-sized cd player from a famous auction site. Cosmetically she is great, however, it won't play at all. She powers up fine, but it will not spin the disc at all. I've done some basic investigation and found that the laser sled moves fine, and if you apply a small voltage across the disc motor, it works, making me think that either the safety switch is faulty or its not getting a signal to start playing a disc. Does anyone have any ideas?

Thanks in advance

Martin



Re: Sony CDP-7F

Had a little play around with this last night, cleaned the laser and its now working, however it plays the first few tracks ok, albeit with what I'd say is a 'scratchy' sound quality, then once it gets past track 5, it jumps and skips all the time until you go to track 8 onwards, then it plays ok though scratchy sounding. I have tried the outputs into my amp via both RCA and the headphone jack, and the sound output is the same on both. However, I see a light at the end of the tunnel as it didn't work at all!

Thanks in advance

Clean the rails that the laser rides on.

Thanks for the info, will give that a try tonight!

Big thank you to Johnnysan for his suggestion, I took the sled apart and cleaned it thoroughly and de-greased it all, and now she plays just fine. Still skips a little on higher tracks, but I'm happy it sounds and works about 95% of the way it should!
