You have a problem with your monitor. Take it to a computer repair place and let them replace the screen. Or if you don't mind having an external all the time, don't worry about repairing it.
the screen on my laptop flickers colors and there are lines running through middle red blue green ect.. and sometimes it will just show a blue screen fades to white ect,, it does work on an external monitor tho what would be the cause to this and what would or could i do to fix it ? i do have pics of what its doing
