The fix worked for awhile then the attached monitor turn blue again. I attached another monitor to the laptop and it's screen was blue also. So I did steps 1-3 again. The screen was blue but shortlywent to normal. The screen now has move back and forth between normal and lite blue. It just now when blue again and has stayed that way. Does it need go to a repair shop?
