Lenovo Y50 - Screen fades from rainbow lines to slowly white and fixes when pressuring the panel

I have a Lenovo y50 2014 which the last month is producing some very strange behaviour.

While working the screen freezes and vertical lines start to show up, the screen starts to get discoloured and slowly fades to white. It has gotten to the point where everytime I turn on the screen, it's first all white then I have to move the screen a little bit to put it "in the right position".


It used to be that adjusting the hinge position a little would fix the problem but now the only thing that helps is pressuring one of the top corners, but the screen will freeze again when released. I first thought it was the ribbon cabble and I purchased a new one but I'm not feeling like changing it since moving the cable connector in the motherboard or screen does not produce any change. I have already tested the GPU by connecting the laptop to an external screen which worked well.


So is the only thing left to blame the LCD screen as a whole? 


Sometimes when I open the panel frame the pressure put would fix the screen and It will be ok for a day unless I adjust the screen but the issue will be back the next day when I turn the laptop again.


I have attached some pictures of screen manifesting the said behaviour. Thank you for you time.

Hi H0meLine,




I guess you have isolated the LCD panel as the point of failure specially if you would need to press the LCD panel to fix the display even when it is out of the LCD bezel.


With replaced cables and isolated on external display, if the same issue happens in the BIOS screen then we are sure that it is a hardware LCD panel issue.
