Laptop screen freezes and turns to green / pink colors
Hello I have y50-70 lenovo laptop
Today when I started the laptop the screen started white then it started to get colors like rainbow like the white color fading slowely and getting these rainbow colors
When I move the laptop lid to a certain degree the screen is normal but after a while it comes back again and I need to move it to get it working , I suspected a loose screen cable and I replaced it but the problem stills there , and when the screen goes like this It doesn't respond, I mean it's not just colored screen it's colored + unresponsive , I tried an external display and it works fine so I don't think it's the graphic driver .
Help please !
Would faulty lcd panel or inverter give symptoms like this ?
Is this a good question?
