Description

• • Application: 32-inch LED LCD TV/15-21-inch LCD power module substitution
  • Pin Definition
  • 1 foot yellow line: DRAIN, power control terminal, connected to the original high-power MOS power supply D pole. Usually the middle foot of the power switch tube
  • 2 feet black or pink wire: GND, module ground wire 300v, capacitor negative, the same line can be. Negative pole directly connected with large filter capacitor
  • 3 foot red wire: VCC, module power supply terminal, connected with the positive pole of capacitor after rectification of feedback winding terminal, continuous power supply, voltage between 12-18V.4 foot white line: FB, regulated feedback, four-foot optocoupler. Make sure that the three-foot optocoupler connects the hot ground. If it is not the hot ground, the optocoupler is shortened to the hot ground. At the same time, the four-foot peripheral circuit is disconnected.
  • 5 feet green line: start start start foot, connect + 300V capacitor positive pole
