My Nitro 5 suddenly had horizontal lines on its screen after working perfectly fine for just over an year. There was no physical damage, no pressure, no bump anytime. I was just watching a video on YT when it suddenly had these lines. I've reset the drivers, booted in safe mode, but lines still persist. A guy at a local repair shop said it could be the display cable issue. But I cannot find the cable online, any solutions?
I live in India, and the screen is 2560x1440, 165Hz, 3ms response (advertised). I've attached photos which show the screen condition and the display cable sticker.
