Black screen and no internal screen detected, works great on external
I have a problem with an Macbook PRO Late-2008 2,4 Ghz Core 2 Duo, Geforce 9400m and with remobable battery
It stars with completly black screen and in any case it works, like it was dead. If I conect to an external monitor the laptop works great on it, no video iusses and nothing worng, perfect in external screen. Them, if I search in "about this MAC..." I can see in display configuration that is shown like if the internal "screen is not conected" and of course "not detected"
The external screen is detected propetly in this menu
I open the laptop and I see that all is very well conected, cable to logic board and to the screen and it seems to be good
Thanks for your time reading this and have a nice day
