Question about Pioneer Audio Players & Recorders
If this is a Pioneer CD player, you may need to do a grating adjustment. Do you have the service manual? What model number is this?
I may be able to help you more with this information.
The grating adjustment is needed on many different Pioneer CD players, mostly the older models. There is a smaill area on the pick up with a copper colored plate that must be moved just a little one way or the other. You put a very small flat head screwdriver in and move this copper plate just a little one way and then try again the other way if it doesn't work the first time.
There is a jig set up that Pioneer outlines in the service manual to do this properly. You need an O-scope as well to moniter a point on the jig. I have done this before without using the jig or O-scope, but it is more presise with these things being used.
This procedure needs to be done in the test mode so the disc is spinning constantly and then do the adjustment while watching the O-scope to know when the adjustment is at the proper position.
If this is a model that I have the service manual for, I can outline the procedure very well for you. But first I need to know the proper model number which I did not see in your post.
Let me know,
