Repairing LCD monitor Benq T905 Q9T4 power supply, it had the mains filter capacitor open circuit and leaky and the fuse and the switching transistor blown. Replaced these components, for the transistor I used a P6NC60FP in place of the original P7NK80ZFP,

Before shipping it monitor the temperature of that mosfet. The current, voltage, and wattage ratings are similar but sometimes a sub just isn't happy..
