ca - 888 super lcd power supply circuit board universal power ules display universal power supply ule. applications: soe 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 els, and variety. often there is no same spare parts, and can not be repaired. the ule 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 ule.
1. remove the power supply chip on the board (usually 8 meters), and switches (mos tube)2. check the 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 ule to the corresponding line, and carefully check that there is no wrong, if wrong, the ule 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
