5、ear Panel (pos 251). Dismantling the Tuner, Mains and AV boards 2) Loosen 4 screws A and 6 catches C1 to slide the Front Panel assembly (pos 101, 102, 103, etc) as per figure 1. Note:To remove the Source / Volume control pc board (pos 1105B) 2 nuts hidden below the control knob assembly (pos 133, 13

6、4 and 135) must first be removed. Hints for re-assembly of Top Cover Due to appearance design the Top cover (pos 252) is sandwiched between the Front panel (pos 101) and the 2 side covers (pos 102 the amplifiers are operational, but the audio is muted - Standby mode; with a very low supply current,

7、the output stage is switched off. DC-detection The DC-detection circuit monitors all 6 outputs for DC. Whenever one or more outputs contain DC for more than 1 second, the circuit will be activated. A positive voltage will activate transistor 7710 and pin 10 of connector 1301 will be pulled down. In

8、case of a negative voltage, transistor 7716 will be activated, which in turn activates 7710. The set microprocessor will take further action. 3104 217 07180 bl110 MECHANICAL EXPLODED VIEW MECHANICAL PARTS LIST & SCREWS 84822 492 11735SPRING, TRANSISTOR 9-D2.3 x 8 Note:Only the parts mentioned in thi
