I don't think it's POSSIBLE for a cable problem to cause this symptom.
That is, I think that the chance of this being a possible cause is 0.0%.
The interface just doesn't work that way.

Massaging the panel may fix the problem but probably any such fix will
be temporary (pressure may provide a jury-rig semi-permanent fix ... for
as long as the pressure is applied). The likely cause is either a bad
driver circuit or a bad interconnect between the actual panel glass and
the driver circuits, all of that being part of the LCD panel itself and
not part of the laptop or the interconnect from the laptop (motherboard
or video board) to the panel.

I was talking about the actual ribbon cable from the inverter to
inside/back of the actual panel.
And Yes a quick reconnect of those teeny tiny connectors can fix this
problem.

You don't know what you are talking about. The connection from the
inverter to the LCD panel is not a ribbon connector at all, it's two
individual wires.
