I have been on a kick the past few weeks of actually playing CDs (I ripped them all 10 years ago, and have essentially been listening on random for a decade) and in the process dug out my first ever CD player, the Sony D5. I thought I'd set this up in our bedroom with a small powered speaker we already have. I dug it out of storage, remembering it hadn't worked about 15 years ago, the last time I attempted to play it. So today, before I even put a disc in, I put lithium grease on the sled as best as I could without disassembling, and cleaned the lens with rubbing alcohol. Put a disc in, and it attempted to read...01, then 00, the spinning stops. I tried multiple discs because I thought that if I could get the laser to move along the sled it might lubricate itself, and lo and behold, ONE CD fired right up, and played about 40 minutes flawlessly before it stopped. (A very late 80s Polygram CD.) Nothing else will play at all, other than this one disc. Any ideas? I'm not really sure what I'm needing to do here to potentially fix this, or why a single disc will play and 10 others will not. Thanks!
