CA-888 Universal LED TV Power Supply Module with DMO465R | 5-Pin Definition | High Compatibility Module
The CA-888 Universal LED TV Power Supply Module with DMO465R is a high-efficiency, compact, and reliable solution designed to replace traditional high-voltage and high-power MOS-based power sections in LED TVs. Featuring a well-organized 5-pin configuration, it ensures stable performance and easy installation across a wide range of LED TV models.
This module is ideal for technicians and hobbyists who need a quick replacement for faulty power supply circuits without the need to change the entire mainboard. Its universal design and straightforward wiring make it a popular choice for repairing and upgrading TVs.
Pin Definition Table:
| Pin No. | Wire Color | Pin Name | Function & Connection Details |
|---|---|---|---|
| 1 | Yellow | DRAIN | Connects to the original high-power MOSFET D-terminal (typically center pin of power switch transistor). Controls main power switching. |
| 2 | Black or Pink | GND | Connects to the ground (negative) side of the large 300V filter capacitor. Acts as the main ground reference. |
| 3 | Red | VCC | Connects to the rectified output (positive) of the feedback winding. Provides module’s operating voltage (typically between 12V – 18V). |
| 4 | White | FB | Connects to the 4th pin of the optocoupler (feedback signal). Important for voltage regulation. (Tip: If no heat on pin 3 of optocoupler, short optocoupler to ground carefully and disconnect FB circuit.) |
| 5 | Green | START | Connects to the positive side of the 300V main filter capacitor. Provides initial start-up voltage. (Important: Follow proper wiring carefully; avoid random connections.) |
