Laptop screen flickering and fading to black
I have an Asus UX501V with touch screen from 2016 which shows some strange problems with the screen recently.
When I start the laptop everything is working just fine. But at some point the screen starts flickering and fades to black (the laptop continues working but the screen just shows its last image fading to stripes or total blackness). When I connect the HDMI to an external screen everything works fine and when I duplicate the screens I can even use the the touch of my malfunctioning screen while its flickering and it will corectly follow on the duplicated screen.
Moving the malfunctioning screen might sometimes help to remove the black screen and show a flickering image again but quite soon it moves back to black. I updated the drivers and disabled and enabled both graphic cards. This didnt seem to be the problem. I suspect a problem with the connection to the screen. But the strange thing is that at some moments it works fine and also at those moments moving the screen doesnt seem to impact the working of it.
The computer shops in my area have no idea how to fix this problem so I hope somebody might be able to help.
