2Pcs 26 Inch-55 Inch / 10-42 Inch Led Tv Constant Current Board Universal Inverter Driver Board Booster

2x Universal Inverter: 1* 26-55 inch + 1* 10-42 inch
The LED Strip Voltage must be between 60V-165V. Not less than 60V, if less than 60V, you can choose our other item..Not higher than 165V, the product design conditions shall not exceed the maximum working voltage of 165V.If the voltage exceeds, the screen will appear dark or flashing lamp and so on.
This product is only constant, not constant voltage, the voltage will automatically adjust to the appropriate voltage according to the led strip need, so you do not worry about in no-load voltage condition measuring how much voltage is.
10-42 inch LED Backlight Lamp Driver Board Constant current board
Now you need to do the two things:
First, attempt to use the remote control after connected to the transfer barefoot
to try brightness, if not resolved,test the actual pin voltage (Note: it will be the greatest brightness in 0V, the brightness will be the darkest in greatest Voltage), if it is an analog voltage mode voltage range is between 0V-5V or 0V-3.3V, if the voltage has been in hight condition all the time andcan not be reduced, now you need to adjust it . the voltage is 3.3V if it is PWM signal, it still can be up to request if adjust to the greatest brightness at this time ,you need to do second program
