1. Right after power is turned on, confirm that the
voltage across the terminals of R1

(SURROUND
Rch), R1
3
2 (FRONT Rch), R1
33
(CENTER), R1
3
1
(FRONT Lch) and R1
35
(SURROUND Lch) are within
the confines of 0.1 mV to 10 mV.
2. If measured voltage exceeds 10 mV, remove R100
(SURROUND Rch), R
96
(FRONT Rch), R
9
7 (CENTER),
R
95
(FRONT Lch) and R
99
(SURROUND 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 removing the resistor.

mV after
6
0 minutes.
