Based on technician reports from platforms like YouTube and Scribd , common points of failure include:
Working on the WLX-896B involves exposed AC mains voltages. The bulk capacitor can hold a lethal charge (300V+) even after the device is unplugged. Always discharge capacitors before touching the board and use an isolation transformer when probing the primary side with an oscilloscope. Conclusion
This chip regulates the switching of the power MOSFET to maintain a steady output. 2. The Transformer and Rectification Stage
