This service manual helped me to repair my PIONEER. Iam very satisfied, that I found it here.
Even the price of manual was not so high that person would not be able to spend a few money.
But that is very worth spent money. Thanks

2.Servo Block 2.1 Focus Servo Block When defect is "H"(the defect signal is detected), the focus servo loop is muting in case of focus phase compensation. At this time, the focus error signal is outputted through the low pass filter formed by connecting a capacitor(0.1uF) and a built-in 470K� resistor to the FDFCT pin(pin 60). Accordingly, the focus error output is held at the error value just before defect error during defect occurring. The peak frequency of focus loop phase compensation is at about 1.2KHz when the resistor connected to FSET pin(pin 6) is 510K�, and it is inversely proportional to the resistor connected to the FSET pin. While the focus search is operating, the FS4 switch is on and then the focus error signal is isolated, accordingly the focus search signal is outputted by FEO pin(pin 48). When the FS2 switch is on(focus on), the focus servo loop is on and the focus error signal from FE2 pin(pin 58) is outputted through the focus servo loop.
