Connect an external monitor to the laptop and watch its' display to see if it behaves the same way or if it stays on when the laptop screen goes dark.
If the external monitor display remains on then it sounds as though you are experiencing a backlight problem.
To verify this, shine a torch at an angle, close to the laptop screen to detect if the image is still there. if you can see whatever image was there before the screen went dark, you have a backlight problem
Does the problem occur if you move the lid of the laptop?
If so it may be a backlight power cable (or video cable - might be in the same cable) problem or a cable connection problem on the display panel.
If the external monitor screen also goes dark, try starting the laptop in "safe mode with networking" and see if the problem occurs. (the screen will look different because you are using basic Windows drivers and no 3rd party programs will start when you start the laptop. This will prove whether it is a 3rd party program (or drivers) that is the cause of the problem or not) - be aware if you go online in this mode there is no Anti Virus running if you have a 3rd party A/V installed! If you have concerns just use 'safe mode' to check for the problem. This way you can't go online
What is the full model number of your laptop and what OS is installed?

On p.49 it details the pre-requisite steps and then the procedure to remove the display panel.

Not saying that you have to remove it but this will help you to gain access to the video cable to check its' connections.

Something is either loose or perhaps it may be jammed in the hinges as moving the lid seems to make it come and go.

If the cable is the problem search online using the ''Dell (insert model number) video flex cable'' in the search box for suppliers of the part.

(I don't think that p65F001 is the model number I think it is the serial number, the model number should be Dell 7xxx as it is a 7000 series laptop.)
