Great care needs to be taken when opening laptops. The first thing you need when repairing laptops are good tools. In the image below we show you the tools needed to fix a backlight inverter. Backlight inverters come in all shapes and sizes. You can buy these from websites like Ebay or you can buy broken laptops and take them out and use the spare parts. Some companies will use old inferior parts. Try to replace the inverter with exactly the same part. Here is what you will need to fix a backlight inverter. Take out the power cord of your laptop and remove the battery.
Look at the images below in the first image we have removed the tube connector to the internal screen. Next we connected a tube that we removed from a broken screen. The tube was still working on the cracked screen but instead of throwing a cracked screen you can use the tubes! Ok Here we connect the new tube to the inverter but the tube does not light up.
In the second image we remove the power cable to the laptop so there is no power at all. Then we connect the new inverter.
The new inverter is now connected up. The power cord is plugged back in. The laptop is booted up.
Just look at that !! Wow the lamp shines like something out of star wars . This new inverter is pushing power to the tube. hooray !!
Ok, so we are impressed with the new inverter now we put the inverter back the screws back and the plastic cover.
The screen now is nice and bright.
