Hello, I am trying to repair a W370ST for a friend. The screen flickers if you tap the laptop or move the hinge. I tore it apart a little bit keyboard off front plastic bezel for the screen and the access panels on the back. It seems to be the cable that runs from the monitor to the mother board. I want to reset the connector just to test but I think it's likely that cable that has broken due to being pinched by the hinge over time. I can't find the connector inside the laptop does anyone know what side I should be looking on? Or maybe someone knows that this is caused by a bad driver etc. Kind regards, Musica
