Product Features:
1.Adopting high quality materials, strong versatility, suitable for 14 inch-70 inch LCD TV ;
2. This power supply module single tube repair power supply problems can be used to support the PFC circuit;
3. Without sampling, need to use the original photocoupler sampling, suitable for photocoupler is not bad;
4. Module body is small and light weight, is the universal universal power module for LCD TVs;
5. Long service life, according to the original board, 3-36V can be automatically adjusted, this product has been improved after a long time of testing, designed specifically for a variety of single-tube switching power supply and the production of power modules.
 
Product Parameters:
Color: green
Output voltage: 3-36V
Applicable: 14inch-70inch LCD TV (original machine with PFC circuit can also be used)
Size: 32*26mm
Scope of application.
1.LCD TV and various single tube, switching power supply, power adapter, set-top box, air conditioning computer board, DVD, monitor, etc..
2. This product uses DC sampling, TL431 feedback amplification, the output of each circuit and the original machine voltage is basically the same.
3. Humanized design, ultra-high power, 70 inches below the night crystal TV, as long as the switching power supply is a single open tube, all easy to solve the problem, the load is light and heavy does not appear to be the case of voltage instability is very stable.
Installation method.
1. Remove the original switching tube and power supply chip or thick film, the membrane block is fixed on the heat sink, 60W power supply does not require an external heat sink.
2. Check whether the 300V counter-peak absorption circuit is normal, and whether the secondary transformer is short-circuited.
3. Red line to the original switching tube C pole, welding point (i.e., 300V over the transformer) field effect tube for the D level.
4 black line to the hot ground. (Negative of the 300V filter capacitor)
5. Green line connected to the 300V (300V filter capacitor positive)
6. yellow line to the four legs of the optocoupler (Note: the three legs of the optocoupler to ground)
7. white line to the original secondary power supply (see chart)
Suggestions for use:
After this module is connected, it is recommended to disconnect the load, connect the dummy load to measure the voltage, check that there is no error, before you can rest assured that the test machine.
