jedyne do czego mogę mieć zastrzeżenie to jakość zdjęć zawartych w przesłanej instrukcji serwisowej ponieważ są fatalnej jakości, praktycznie nieczytelne. tak poza tym jestem zadowolony to jest to czego szukałem.

APC circuit input. VCC of RF signal circuits. Input to control the DSP's data slice level. Ground of digital signals. Output for the focus search smoothing capacitor. The TBC (tracking balance control) signal sets the EF balance variation range. Not connected. Disc defect detection output. Reference clock input. 4.23 MHz is input from the DSP. Microprocessor command clock input. Microprocessor command data input. Microprocessor chip enable input. DRF (detect RF) is an output to detect the RF level. The FSS (focus search select) signal switches the focus search modes (+/-search / +search with
Sets the RF gain and the EFM signal's 3T compensation constant together with the RFSM pin. The SLC (slice level control) signal is output to control the DSP's data slice level of the RF
