To replace your laptop screen, we have to first make sure that your screen actually needs repair. You may have dropped your laptop, and after seeing that it isn’t displaying an image, simply assumed that the screen must have broken. The screen might even be cracked a little, and yet that still might not be the reason you can’t get an image.
If your laptop has a VGA output, we connect it to a desktop monitor or television to see if it shows the image correctly. If it still doesn’t show, it means that your graphics card or motherboard is probably damaged. If this is the case, we would suggest replacing these components. Only when we can see an image on an external monitor but not your laptop screen do we replace the screen.
We may discover is that we may see a dull image on your laptop screen, or the backlight may flicker on and off. If this is the case, it is probably caused by a faulty inverter. If so, we contact you to suggest replacing the inverter and see if that fixes the problem. If we don’t see any image at all on your laptop screen, but the laptop displays fine on an external monitor, we know it’s time to replace the laptop screen..
