Laptop LCD Problems?

When talking about laptop problems, heat is not the only problem you'll encounter, since the LCD is also prone to more frequent problems, when compared to a desktop computer. The laptop LCD problems we'll talk about today are faint image/very dark display, and solid white/garbled screen. I just hope you're reading this article looking for solutions to anyone else's laptop, and not yours...
First of all, let's see what can be done if your laptop LCD screen has a faint image or - even worse - the image displayed is very dark:
1. Before anything else, check the display settings in Windows and using the controls on your laptop - if any;
2. Now, if the image you see on your computer can't be adjusted at all, is possible that the laptop's LCD lid close switch is simply stuck in the closed position. Obviously, this makes backlight to stay off, even with the LCD lid open, to save power when the laptop is ON, but the lid is closed.
3. Close to the back LCD hinges, you will find the close switch - it looks like a small plastic pin, you can't miss it.
4. Tap the switch a few times, and see if this helps. If it doesn't, then you will probably have to replace the FL inverter board.
Next, we have another problem - what if your LCD screen is simply showing solid white, or garbled images?
1. Connect an external computer monitor to the laptop and see how it behaves.
2. If the external monitor shows what your LCD should, then you have a problem with the laptop LCD screen, or your LCD cable connection.
3. Obviously, if the external monitor image is also white/garbled, then your graphics adapter may be in trouble, but it could also be a video driver-related issue. Try to see if booting in Safe Mode helps.
4. If you can boot in Safe Mode, install the latest video drivers.
5. If you can't boot in Safe Mode, than probably you'll need a new motherboard for your laptop.
That's if for now, and I will say it once again - I hope you didn't come hear to read about the problems of your own laptop. Anyway, no matter the reason, I bid you good luck in your laptop troubleshooting quests!
