Computer fell and screen does not work anymore
My mid 2011 i7 MBA fell from standing up to lying down, not very dramatic and it was on a carpet. Nevertheless my screen does not work anymore.
It only gives random vertical lines and it changes when I bend the screen slightly. If i try to connect an external screen to the thunderbolt nothing happens.
I took it apart hoping that it was only the connector that might have fallen out of place but seeing it I realise that is not very likely.
I can connect from another computer via screensharing and on the network the macbook works perfect.
Any ideas? The fact that an external screen does not work either, indicates to me that the graphics card might be busted, or?
I am wondering if it is worth buying another screen assembly and change it. Is there any troubleshooting software available to see the function of the onboard graphics?
Is this a good question?
