Buffalo Smart Rice Cooker Repair Panel Switch Fault

In this video, I demonstrate how to diagnose and repair a Buffalo Smart Rice Cooker with an unresponsive panel switch. After troubleshooting, the actual cause was found to be a damaged PCB copper track. The PCB track had burnt and separated due to prolonged heat generated by current flow, combined with oxidation, resulting in an open circuit. Because of this, the panel switch could no longer function correctly. Instead of replacing the entire control board, the damaged PCB track was carefully repaired, restoring the rice cooker to normal operation. 📌 What you’ll learn in this video: How to diagnose a faulty control panel. How to inspect a PCB for burnt or broken copper tracks. Why PCB tracks can fail due to heat and oxidation. Step-by-step PCB track repair technique.
