Yes if both of them are disconnected.

->Both sides of amplifiers (L/R) seem broken.

Yes if P5610I is disconnected.

->Any of amplifiers (R/C/SR/SBR-CH) for right seem broken.

Measure the values of resistance between Base and Collector of Transistors Q605x,Q606x, Q608x,Q609x

If the value is 0 ohm or infinity, the transistor seems broken. See which channel is broken by the last digit. x=0 : Left ch x=1 : Right ch x=2 : Center ch x=3 : Left Surround ch x=4 : Right Surround ch x=5 : Left Surround Back ch x=6 : Right Surround Back ch

In the same way, check Transistors Q603x,Q604x,Q610x,Q611x. Measure the values of resistance at Resistor R607x,R625x,R626x,R627x,R628x, R629x,R630x,R631x,R633x,R634x, R635x,R636x. If the value is infinity or 0 ohm, the resistor seems broken.

Yes if P5610I is disconnected.

->Any of amplifiers (L/SL/SBL-CH) for left seem broken.

High impedance at all the transistors.

The value is 0 ohm or infinity at any of them.

Find which channel has a problem and then check the channel thoroughly.

Disconnect Connectors P5610I and/or P5610K and turn on the power. Does the unit work properly?

No even if both of them are disconnected.

Main amplifier section has

no problem.

Check the other sections.

Measure the values of resistance at both ends of Cement Resistors R640x,R641x, R650x,R651x. They should be about 0.22ohm.
