A "good" rework isn't just about cleaning the board; it’s about correcting the electrical engineering errors. Here are the primary focus areas: 1. Power Rail Stabilization Power Rail Stabilization Resistor 1 : Replace the
: Replace the resistor marked with a green dot on the PCB with a 4.7k ohm resistor.
