Screen background is red

Hi,

It seems like a hardware problem already, your LCD to be specific. Here are some troubleshooting steps that may help.
- First is to test the GPU as well.
- Connect an external monitor and see if the same problem will persist or not.
- If the external monitor will display normally that means it's just the built in display that is faulty.
- But the external monitor will also result to the same problem that means the GPU is faulty.
- What you can also do is to check the ribbon cable that connects the LCD to the motherboard.
- If it will still not work replace the display itself.
