The fix for this was to plug in an external monitor and change the notebook display's refresh rate.  Per customer " The LCD screen of the laptop was on the wrong Refresh rate but I managed to reset it on the default settings and it has been working normally since."  
I switched my laptop off about 2:00 AM this morning and started it again about 6:00 AM and now the screen is like if it was damaged. tried rebooting it but it does get better or like this time worse. [IMAGE]
