My Laptop is 13 months old Dell I7 5558, i was facing this screen flicker issue previously ,where i got my Laptop Screen replaced by you ,but now I'm facing the same issue .
Previously before replacing i used to have just few flicker,now flicker rate got increased even more & Screen Goes black which is really annoying.
Even at the logo Screen I 'm seeing Green & pink lines
Sometimes nothing appears on the screen just flicker of Green & pink lines & black Screen After that.
Where i should to remove my battery & place it ,to turn on my laptop in this case.
Problem is not related to software, if that was the case flicker should not be at dell logo screen.
But FYI my Graphic Card Drivers are already up to date.
I Guess the problem is at the hinges or with the monitor or maybe related to mother board itself.
when my laptop screen is less than 90 degree i can see few flicker,when it 90 degrees or more than that ,continuous flicker & black screen later as like monitor looses power nothing .
Any Other Information Required let me know.
