Hello all, I have a screen display problem with my Lenovo Y50. There's this blurry striped (thin horizontal lines) darker or brighter area from left to right on the lower part of the screen.
I don't remember when the problem started, perhaps either it's caused by bumps or a bad ram stick. When I connect it to the external monitor, the display is normal and the area doesn't appear. Does anyone have any input for a solution to fix it? can I fix it by replacing the LCD ?
