Purpose: to solve the 17-21 inch LCD monitor power failure maintenance problems

Pin Definitions

Yellow Line: DRAIN, power control terminal connected to the original high-power MOS tube D pole.

Black line: GND, the module ground 300v, then negative capacitance can be on the same line.

Red: VCC, module supply side, the positive feedback received after the end of the rectifier winding capacitance, continuity of supply voltage between 12-18V.

White lines: FB, regulator feedback, then optocoupler 4 feet, 3 feet to make sure optocoupler heat, the earth is not hot, then put the optocoupler shorted to ground heat, while the 4-pin peripheral circuit is disconnected. '

Green Line: start start foot, connected +300 V capacitor positive.

Usage:

1. Remove the power chip (typically 8 feet) on the original board, and switch (mos tube)

2. Check 300v capacitor, there was the appearance on the load side of the capacitor is no drum kits, there are problems on the first replacement

3. Check the load side there is no short circuit, ad plate, pressure plate, etc.

Note:

1. Before using this module, there is no need to detect short-circuit the cold side, there is a short circuit in the first repaired, if the need to replace the capacitor drum kits, ignition coil circuit shorted Esen disconnected, no prior on the module, removed the original chip and module power mos tube, this time the original switch in the middle of the electrode to heat to have voltage 300v voltage around.

2. Optocoupler 3 feet, if not Connected the heat, the heat please 3 feet to ground, while the demolition of empty 4-pin peripheral circuit, and the white wire to the position 4 feet.
