The units operation when a DC/OVER/TEMP error is detected is described here. How to cancel the status after detection of a DC error is described here, because no key input will be accepted after a DC error detection. *1 The time required for the unit to be shut off after an error is detected depends on the circuit configuration. *2 If the unit is automatically shut off after a DC error is detected, no key input will be accepted afterward. (The power will not be turned ON.) To turn it on again, see “3.4 How to cancel the status after detection of a DC error” below. A key input will not be inhibited after an OVERLOAD/TEMP error is detected. (The unit can be turned ON.) Simultaneously holding the ADVANCD SURROUND and STANDBY/ON keys on the front panel pressed for 2 seconds will cancel Key Input Inhibition mode after a DC error detection and turn the unit ON.

Discharging (1) Unplug the power cord. (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) Connect 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 between 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 (Pins 1 and 2) of the P.C.B SUB Assy (FRONT) and GND (Pins 3 and 4, respectively), using resistor leads with 47-100 ohms (2 W or higher), for discharging. *Discharging time: 5-10 seconds, depending on the level of resistance. (3) Check that the voltage between the -30 V 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 (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 the photos and illustrations in this manual may differ from your product, the procedures described here are common. Note 2: For performing the diagnosis shown below, the following jigs for service is required: 10P board to board extension jig cable (GGD1628) 8P board to board extension jig cable (GGD1629) Board to board extension jig cable (GGD1630) RadioFans.CN 收音机爱 好者资料库 36SX-319V-K 1234 A B C D E F 1234 2. 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 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 removed, 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.
