Display becomes black after a minute or more

MBP model is A2159. I am able to view the login screen properly upon opening the lid. I can type in the password and can reach the home screen.

After some time (the shortest being 5 seconds and the longest being 1 minute) the screen goes black with blueish vertical lines as shown below.

During this time the screen stays undisturbed. Every time I open the lid the display shows up correctly and then goes black. What can be the issue here?

Can it be a display (LCD) issue?
Can it be a problem with the flex cables?

The screen that I am getting is similar to the issue posted here: Black screen with blue vertical lines on MacBook Pro

Appreciate if someone could help me on this.

Your issue is not the flex cables, what you are seeing is the screen resolution change from the lower clocking to the higher clocking. What happens is the T-CON logic which is part of the display assembly can’t comply to the logic boards change so you get this image.

Basically the display assembly has failed ;-{

To prove it connect an external display it should work with no issues while your internal ends up being a black screen.
