What are the parts that are creating this problem?? Can you pls tell
Like I said, either screen is bad or the system is, motherboard or video card chip. There is no way to tell without taking it apart and trying different parts, RAM, checking screen connections, trying another screen and so on.
This started out of no-where or did it get dropped or spilled on, anything change like a Windows update, etc...?
Did you try an external monitor?
