Hi, the left channel of my wm-d6 now is almost inaudible in the line OUT and headphones, I checked the IC101 - CX174A-2 voltages pin1 to 16, I put 5V for the CD input using a variable power supply: IC101 - CX174A-2 voltages: pin 1: 0 V - pin 16: 4.982 V pin 2: 5.802 V - pin 15: 5.052 V pin 3: 4.852 V - pin 14: 5.015 V pin 4: 4.957 V - pin 13: 4.930 V pin 5: 5.125 V - pin 12: 0 V pin 6: 5.075 V - pin 11: 4.944 V pin 7: 5.082 V - pin 10: 4.878 V pin 8: 10.85 V - pin 9: 1.169 V on the right channel that is sounding normally ic 201 - CX174A-2 these voltages are different: pin 9: 5.504 V, pin 10: 5.300 V, pin 11: 5.475 V I have checked the surrounding but I'm in unknown territory, on another wm-d6 the pin 9 of the ic101 the voltage is 5.775 V so i don't know could be the IC or something behind, if someone can help me, I was fixing that the tape was being eating and something else happened, I don't see any cable loose or disconnected. thank you.
