My very well operating laptop monitor has recently started malfunctioning. Occasionaly, the pictures on the monitor disappear; the screen takes various colors, sometimes black. When I rotate by moving the monitor forward and backward, it recovers. I have checked the "Device Manager"; both monitor and graphics card drivers are updated. As you know, the monitor body is connected to the laptop by means of a hinge-like arrangement. I guess that the monitor cable is attached to a part which can revolve in this hinge; maybe it is another mechanism, which I don't know. I think there is a contact problem here. How can I enter this region and how can I fix this problem? I would very much appreciate if you give me the related information. Also, as I hear, in YouTube there are some videos related to this kind of issues. I would appreciate for your sending if you are aware of any links of this kind. Thank you very much in advance.
