What type of ic is this AP4411 used in the inverter section of HP f1703 LCD Monitor? At current moment it is hard to find such datasheet or specification for this 4411 IC. It is actually a P-channel enhancement mode mosfet which built into the SOC 8 package ic where pin 4 is the gate, pin 1-3 are source and pin 5-8 are drain. You can test it with a meter if you want but because of the IC in small size, i have to use the peak electronic atlas analyzer to measure it.
This AP4411 IC is part of the buck royer inverter circuit in the HP f1703 LCD Monitor. If this IC has become defective, it will cause power to blink or even dim display
