Thank you very much for this Service Manual, it helped us a lot to repair the M-4318!
...BUT: The parts list is missing and the free parts katalog on web isn't complete, so now we don't know the part numbers of the defect parts :(
We had to build them out of a working machine, and need the numbers to reorder the missing parts now.
Great manual, thank you, sony kp46s3 service manual perfectly, i am very happy.

Mechanism Assembly (Type B)
Note: The pickup mechanism assembly has two types, A and B of which shapes differ. For the SD-4700/5700, only Type A is a service part. Type B can be changed to Type A pickup free from any performance problem. Type A also has two types, but either of the part can be used for service.
