Hello, I am rescuing this issue because I have problems with a Denon dcd-S10 player that is the same as the DCD 3000 we are talking about.
"Bratwurst7s" you are an artist, magnificent restoration. Can you help me?
My Denon DCD S10 cd player stopped reading discs. The lens did not move and it did not recognize any disc.
Buy two KSS-240 pickups (China) because replacement is easy. When I installed them neither of the two heads made the disk work. The lens was moving but the spindle motor would not start.
I looked at the service manual and it has a self-adjusting digital servo that needs a test disk.
I put a normal disk, but the instructions are a little confusing and the player doesn't seem to react exactly as stated, this most likely means only that I'm not doing it correctly.
The PCB does not have a potentiometer for adjusting the focus gain, tracking, etc.
The mechanical parts seemed to be fine, I went through all the things that I have read in this forum. Also to make sure I was able to buy a cheap Denon DCD-615 player that worked perfectly and with an original KSS-240 head. It has the same table where the pickup is installed and also a kss-240. So I could rule out that it was the spindle motor or the tracking motor.
With the original KSS-240 table and head of the dcd-615 model the spindle motor was still not moving. Since I didn't have much to lose I put back a Chinese pickup and moved the EF BALANCE pot counterclockwise, then it recognized the TOC and a few discs played to the end, but many had skips, tracking problems, access to slow tracks , stops ...
I also moved the FOCUS BIAS pot a bit but nothing improved.
My questions:
When changing the pickup, how can the adjustments be made?
Is it necessary to have the test disk to run the service program? (Impossible to get)
Is it possible to adjust by moving only the EF bias and EF balance pots with an oscilloscope at the test points?
Could a control signal in the digital servo circuits be wrong?
(Now I have 3 kss-240 heads (one original) and a player that doesn't work)
Thank you. (sorry for my English)
