■ POWER AMPLIFIER ADJUSTMENT
1. Right after power is turned on, confirm that the voltage across the terminals of R1152 (SURROUND BACK Rch), R1154
(SURROUND Rch), R1150 (FRONT Rch), R1148 (CENTER), R1149 (FRONT Lch), R1153 (SURROUND Lch) and R1151
(SURROUND BACK Lch) are within the confines of 0.1 mV to 10 mV.
2. If measured voltage exceeds 10 mV, open (cut off) R1104 (SURROUND BACK Rch), R1106 (SURROUND Rch), R1102 (FRONT
Rch), R1100 (CENTER), R1101 (FRONT Lch), R1105 (SURROUND Lch) and R1103 (SURROUND BACK Lch), 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 cutting the resistor.
3. Confirm that the voltage is within the confines of 0.2 mV to 15 mV after 60 minutes.
