Hello Guy, I have sent you an email with a link to the Vintage Solid State forum at I can only suggest that you post a question on AudioKarma forums, asking if anyone can refer you to someone who can restore your CDP-101. Please bear in mind that what is addressed in the article presented here might not address the specific problem you are having, so you need someone who can take on a general repair. Best Wishes.

Hi Brian, Thank you for the follow up. That's a very interesting post that you mentioned. I will be very interested to hear how it goes if you re-grease the slide. While I was doubtful of that fixing the problem, it certainly is a possibility. Could you post a link to the thread, here? I will post the results of my efforts on the CDP-101 here, as soon as I get a chance to work on the player.

Sorry to hear your 101 has developed a problems and thank you for the good thoughts. The strange thing is that the first time I started the unit up after hibernation, it played a demanding CD perfectly. It won't do that now, however. I did see a post earlier today on another site. The writer was having the same problem I am experiencing and he said he re-greased the "laser slide." and that solved the problem. I'll take a look later and do some more cleaning. I'll let you know any result. I'd very much enjoy reading a post on the diagnostics on your 101. I hope the problem is easily solved.

All the Best,

Hi Brian, Congratulations on fixing the door issues! I suppose that it's conceivable that slide/drive lubrication could be affecting tracking but it doesn't seem likely to me. It is typical that skipping is seen first at the inner tracks. That's because the CD rotates faster there than at the outer tracks. This is due to the constant linear velocity at which the system operates. Faster rotation makes it more of a challenge for the tracking servo system to deal with CDs which happen not to be centered as well as others.

There are quite a few things which can degrade the tracking. It could be as simple as the offset or gain adjustments in the tracking servo. Problems in the tracking pickup diodes or electronics could cause it too. I guess at this point it would be best to seek assistance from someone who is knowledgeable about troubleshooting and aligning CD players, as you mentioned earlier.

By the way, my own CDP-101 has recently developed the same symptoms, so I have it slated for repair as soon as I can get to it. Unfortunately, I'm in the middle of another project, so that might be weeks away. I've pressed a CDP-200 into service in its place, for the time being. I can post what I find out about the CDP-101 here, if it's of interest.

Thank you for the great advice. I have cleaned and regreased the door slides and the door is working well again. The tracking problems are one of the reasons I retired the unit. I have to have the "auto shock" switch on in order to track a disk successfully. Occasionally, a whole disk will play with no skips, but usually, the unit has problems tracking the first 2 or 3 tracks and will bounce around a lot. After that (track 3 and up), it usually plays perfectly. it seems the issue is related to tracking the inner part of the disk. I cleaned the laser lens, but I still have the problems. Could this be a lube issue, too?

Thanks again and all the best,
