Hello,
in my laptop Acer Aspire E1-571, the monitor is flickering at regular intervals, as you can see in the following video:

When laptop is connected to an external monitor or TV (VGA or HDMI), there isn’t any defect.[br]
There is no difference if I move the monitor up and down, it continues flickering at regular intervals.
I can see defect always, during boot or in windows.
Where do you think could be the problem?
Thank you in advance,[br]
Sergio
