I've had an Asus N580V laptop for less than a year now, but about 3-4 months ago started seeing an issue crop up with screen flickering.
Sometimes the screen simply flickers to black for a moment, other times there are visual artifacts - bright horizontal lines on a dark screen, or rectangular portions of the screen that flicker into a sort of white noise / static pattern.
The flickering does not seem to be caused by opening/closing the lid, shaking of the laptop, or any pressure applied around the casing, screen bezel, etc.
I opened the back case and removed any dust with compressed air, but the issue is still there. It's very hard to pin down because it's relatively infrequent.
When I plug the laptop into another monitor via HDMI, the monitor doesn't exhibit the flickering, but the video and audio signal will cut out from time to time for a brief second, leading me to believe it's GPU related.
My only theories are 1) GPU overheating 2) GPU/inverter/backlight/some other hardware that's failing (although when it's not flickering, the display is fine).
That said, I've seen the flickering occur when CPU and GPU are only around 40 degrees Celsius, so the heat issue seems unlikely as well.
Any ideas before I resign myself to shipping it in to Asus? Thanks.
