Desolder and remove the blown IC from the A220 PCB. Identify the three critical trace points on the diagram: Audio Input (from Pin 1 trace), Power Ground/Positive Rail (from Pins 3 and 5 traces), and Speaker Output (from Pin 4 trace). Run jumper wires from these points on the original board directly to the corresponding Input, Power, and Output terminals of your replacement Class-D module.
