Turns out my rush to swap parts was just wasting time and money
Honestly, I had this bad habit where if a device acted up, I'd instantly think a component was dead. Tbh, ordering new chips and capacitors felt like progress. After I replaced a whole board only to find a cracked solder joint, it hit me. Now I force myself to inspect every solder point and trace first, and my part costs have dropped big time. Ngl, feeling pretty silly for not doing this years ago.
