Hi @sergio_78
Check to see if it also occurs when in BIOS settings area just to eliminate the remote possibility that it may be an OS problem
It sounds though that it may be a loose LVDS cable connection on the motherboard or the display panel or a faulty LCD display panel.
Here’s the ifixit [[Topic:Acer Aspire E1-571]] guide. This will help to gain access to the motherboard and the display panel so that the cable connections can be inspected.
The above is only what I think based on your question and not having seen the video because not everybody has a Google account so that your video can be viewed. Try posting the video direct on ifixit. Here’s how to do this. [guide|21499]
