10Pcs/Lot Ca-888 15-24 Inch 12-18V Universal Lcd Display Monitor Power Supply Board Module Tv Maintenance Repair Parts

ca - 888 super lcd power supply circuit board universal power modules display universal power supply module. applications: solve the 15 - 24 - inch lcd monitor power supply maintenance problems . lcd tv power board damage a large proportion. one of the power, the chip, high power switch

sampling resistance damage is the most common because these component models, and variety. often there is no same spare parts, and can not be repaired. the module has: wiring is simple, easy to install, save time, improve the success rate of maintenance and so on. the maintenance problems of friends met may consider the development of a universal power supply module.

1. remove the power supply chip on the board (usually 8 meters), and switches (mos tube)2. check the capacitor 300 v, and the capacity of lastseite of the package, there is no drum, a problem on the first replacement. 3. check the last page, 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, the module burst. 5. installed in the original position of the radiator, ensure insulation, short circuit

6. power, measuring voltage is not the performance, there is no issue, then check the cause
