Laptop screen vertical lines, stop after 5 mins / when screen pressed

Laptop: hp power 15-cb060sa

My laptop recently started having vertical lines on left hand side of screen covering about 20% of screen.

These lines dissapear :

• After the laptop has been on for about 5 mins.
• After pressing on the bezzle near where the monitor cable is.
• After tilting the screen until they stop.

I have reseated the monitor cable on motherboard. I was unable to reseat the connection from the cable to screen because it is seated directly onto pcb, not a connection plug.
