(2) Disconnect the 8P CONNECTOR wire that connects the CN202 of the P.C.B SUB Assy (AMP) and CP107 of the P.C.B SUB Assy (MAIN) from the CP107. (3) Con

34、nect CP107 B+ (Pins 5 and 6) and B- (Pins 7 and 8, respectively) terminals, using resistor leads with 47-100 ohms (2 W or higher), for discharging. *Discharging time: 30-60 seconds, depending on the level of resistance. (4) Check that the voltage between the B+ and GND terminals, as well as that bet

35、ween the B- and GND terminals, is less than 1 V, using a tester. *Be sure to connect the GND terminal of the tester to the chassis. *If the voltage is still 1 V or higher, repeat Step (3). 1 P.C.B SUB ASSY (MAIN) Capacitor (C179, C180) Procedures (1) Unplug the power cord. (2) Connect CP704 -30 V (P

(3) Check that the voltage between the -30 V and GND terminals is less than

37、1 V, using a tester. *Be sure to connect the GND terminal of the tester to the chassis. *If the voltage is still 1 V or higher, repeat Step (2). 2 FL-30 V Capacitor Procedures 47-100 ohms (2 W or higher) 47-100 ohms (2 W or higher) CP107 P.C.B SUB Assy (FRONT) B+ B- Note 1: Even if the unit shown in

Notes on Ground Points Connection When reassembling after disassembling the product for repair, before connecting the power cord, make sure that the 2P wire from the CN206 of the P.C.B

40、SUB Assy (DSP) is connected to the CP803 of the P.C.B TOTAL Assy (INPUT). If the power is turned ON without the above connection, the CODEC IC (IC109: AK4588) of the P.C.B SUB Assy (DSP) may be damaged. Note 1 During repair, before checking the P.C.B SUB Assy (MAIN), etc., with the rear chassis remo

41、ved, be sure to connect the GND terminal of the main capacitor to the rear chassis (TUNER PACK CHASSIS), as shown below, then connect the power cord. Without grounding connection, the protection circuit will be activated. After repairing, be sure to remove the ground wire before reassembling. Note 2
