Has one really fixed laptop screen vertical line(s) so confidently help out here now ?

Many say the laptop screen vertical line(s) is caused by defective Embedded DisplayPort (EDP) cable which is slipped into and passed through either laptop screen hinge but on old laptop, Lenovo ideapad, this cable lead to a small thin PCB, ~ 1x7 cm on the screen frame, with quite big mark "Don't Touch" at side, discouraging to check it further to determine whether the cable and/or PCB it is connected to is really the fault or not, i.e. another component part tasked to perform displaying is so.

Therefore asking help to elaborate definitively the real, useful knowledge on repairing this kind of fault in the complete, correct way, able to decide which part is mostly faulty and whether it must be replaced
