Laptop Screen White

Sounds like you have a section of dead pixels. This can happen if the laptop has been dropped a lot or stepped on or some type of impact on the laptop. This is a hardware issue. You will need to have the screen replaced. In my opinion, by the age of the laptop, its better off getting a new one.

I would try using an external display. That will prove the GPU. If it is OK then the display is faulty, if not the GPU is faulty.

You can use the following website to try and fix some of these pixels that are stuck on the wrong colors:

However, it may just be a defective screen. You may need to have it replaced under warranty (and this most definitely will be covered)

It could be due to some loosing insde the laptop screen. In my view there are two things.
1. The data connection between the laptop motherboard and the screen (through cable)
2. The connectors inside the screen.

It is highly recommended that you get the laptop checked by a professional to avoid any further damage to it.

Good Luck!
Hope this helps!

Hello,

The problem is not from the inverter of the laptop. It is the module that is faulty, the module is like a flex in the laptop that assists in getting information from the motherboard to the screen, if it is faulty, it will start showing weird colors or start having some screen malfunctions.

Have the module replaced and the laptop will be in good condition once again. I had such experience with my HP530 and i replaced the module, trust me it worked perfectly fine.

Take care and good luck

Hold one side of the screen need top and flex slightly (Not twist, FLEX) if the full screen appears and lines are gone, you may need to have this fixed by a shop or replaced totally.

the reason for the weird lines is because the lcd is going bad and will need to be replaced.

scane for virus and reinstall the operating system
