A quick update - I had some chance to work on the unit and check all power transistors (Q7 - Q11) for channels with DMM, all seems to be fine. The respective collector resistors are ok as well. I decided to re-solder one of the SDK CHIP (for surround sound), the other one is still out and i am in diagnostic mode. I also checked voltages on the connectors, compare with service manual and seems to be correct
CB136 - have 5.5 V and -40v for -VP
CB134 - has + and - 12v as well -40v for -VP, PS-pRT is 1.02 as oppose to 1.6 but i think it is within tolerance.
CB132- has correct/close engouh voltages - 8.6V, 2.2V, 6.5V, 0V - not sure about pin 2, it should be 3.3V i am getting 2.2.
I need to figure out to connect all boards outside of the unit so i can measure voltages on the power transistors, may be deal with it tomorrow.
Any help and suggestions would be appreciated.
Majorbob, would appreciate any help regarding the resistor numbersl. SO far i checked few resistors, R93, R112, R113, R114, R67, R69,R65,R75,R63,R62,R70,R73,R76R80,
Saga continue for another day.
