I recently found that when booting up, my display would work fine right up until Windows boots up and then the screen goes black, the back-light remains illuminated but there is no display. When I use the FN + F6 key to set to 'Duplicate' or 'Extend' my display comes back but will NOT work when set to 'Disconnect Projector', when I set this the screen goes black, no back-light and FN + F6 no longer works.
When I snoop around in the display settings, it says that my Laptop display is the primary display but that there is a VGA connection active as a secondary display. I have cleaned and reseated all the components and have cleaned out the ports as well as I can (Paintbrush and Methylated Spirits)
Does anybody know where to go from here or has had similar issues? My next plan is to re-install Windows and see if this is the problem?
