Product Description

Power Supply Board - CA-888

Description

LCD power board damage a large proportion. One of the power to drive the chip, high-power power switch, sampling resistor damage is the most common, because of these component models, variety, often because there is no same spare parts, and can not be repaired easily. This module has: wiring in simple & easy way to install, save time. Encountered the maintenance problems of friends may wish to consider the development of this under a universal power supply module.to solve the 15-21-inch LCD monitor power supply maintenance problems

Pin Definition: 
1PIN yellow line: DRAIN, power control side, then the original high-power MOS power supply D-pole. Generally the middle of the power switch tube feet
2PIN black line or powder line: GND, module ground 300v, then the negative capacitor, the same line can be. Directly connected to a large filter capacitor negative
3PIN red line: VCC, the module power supply side, then the feedback winding terminal rectifier capacitor after the positive, continuous power supply, the voltage between 12-18V.
4PIN white line: FB, voltage feedback, then optocoupler 4 feet, please check the optocoupler 3 feet heat, not heat, then put the optocoupler short to the hot ground, while the 4-pin peripheral circuit disconnected.
5PIN green line: start start pin, then  300 v capacitor positive Customers must be optimistic about the specific connection method after modification, do not blindly random access.
 
Use :
 
1. Remove the original power supply chip on the board (usually 8 feet), and the switch (mos tube)
2. Check the 300v capacitor, as well as the capacitance of the load side of the package there is no drum, a problem on the first replacement
3. Check the load side there is no short circuit, ad board, high voltage board
4. Connect the module to the corresponding line, and carefully check that there is no wrong, if wrong can cause the module burst
5. Installed in the original location of the radiator, pay attention to insulation, not short-circuit
6. Power, measuring voltage is not the output, there is no output, then check the cause.
