Laptop Screen regular horizontal lines
I have a Samsung NP350V5C which is briefly displaying horizontal lines over 75-100% of the screen, almost like interference.
The video is perfect on an external monitor, so GPU issues are eliminated and it has to be between the motherboard and the screen.
Thinking it was probably a faulty LVDS cable I replaced it with a new one - with no improvement.
I have noticed that the 'interference' is very regular - 1.5 seconds long, every 3 seconds.
Ist dies eine gute Frage?
