POWER AMPLIFIER ADJUSTMENT
1. Right after power is turned on, confirm that the voltage across the terminals of R11

3 (SURROUND
Lch) and R11
5
1 (FRONT Rch) are within the confines of 0.1 mV to 10 mV.
2. If measured voltage exceeds 10 mV, remove R1104 (CENTER), R1106 (SURROUND Rch), R1102 (FRONT Lch),
R1100 (SURROUND BACK Lch), R1101 (SURROUND BACK Rch), R110
5
(SURROUND Lch) and R1103 (FRONT
Rch), and then reconfirm the voltage.
Attention
If the measured voltage exceeds 10 mV after repairing the power amplifier, check other parts again for any possible
defect before removing the resistor.
3. Confirm that the voltage is within the confines of 0.2 mV to 1
5
mV after 60 minutes.
