What is Laptop Screen Light? What is the problem with laptop screen light? :-

Friends, today in this post we will know in detail about the defects related to light in the screen of laptop.

Laptop screen light  : -

Let us see what can happen in the time of light in our laptop and we can fix it.

How to fix If the light is not coming in the screen of our laptop, then the most

First we will open the panel of the laptop, first of all we will find out whether it is SCREEN LCD or LED.

 Note : -

 The way to find out whether SCREEN is LCD or LED is given in the panel section of the laptop.

After finding out that LCD or LED is lcd, then first of all we will check by changing the power inverter {ccfl}.

In most laptops, the problem of light comes due to the failure of the power inverter {ccfl}.

 This problem goes away by installing power inverter {ccfl}, many times to install a new power inverter {ccfl}

Even after the light does not come, then for this problem we will check the power supply coming from the motherboard.

Inside this supply one pin {-}, ground second pin 18.5 v+ and third pin 3.5 v + and fourth pin

adj i.e. are for adjustment - pin can be more or less work in any laptop

But power inverter {ccfl } needs -, 18.5v, 3.3v, to run if these volts are not getting

So the power inverter {ccfl} will not work and the light will not come in the screen, for this we

Universal power inverter {ccfl} can be installed to install the universal power inverter {ccfl} correctly

For this we will solder the pins coming from the motherboard on the pin written above the power inverter {ccfl }.

Pin and volt of universal power inverter {ccfl} :-

1. ON will connect the 3.5v key on this pin.

2. On this pin let's connect the 18.5v pin.

3. GND connect the ( – ) pin on this pin.

4. ADJs leave this pin free.

Many times, even after installing a new power inverter {ccfl}, the light does not come even after applying the light, then either the power inverter {ccfl} is bad or not supported.

If we have been, then we can install this universal power inverter {ccfl } on many times after applying power inverter {ccfl }

If 3.5 volt is not coming on the pin, then we connect the cable inside the lcd where the lcd is connected, above that connector

By connecting the 3.5 volt supply to the FUSE with the help of a jumper, you can give it to the power inverter {ccfl}.
