"What makes this a bit tricky is that the component labels on the board do not match the schematic. Can you post the numbers on the transistor to the left of the circled resistor in your picture? Also, what are the color bands on that resistor and the one next to it?
This portion of the board is for the front left channel of the amp. It looks like the outputs for that channel are shorted and causing the amp to go into “protect” mode. Can you test the transistors in that area for shorts? These should be numbered B1560 and D2390 (on the parts themselves). This is shorthand for the actual part numbers: 2SB1560 and 2SD2390.
With the transistor number requested, I can verify that I am at the correct point in the schematic.
