I have a netbook and sometimes I connect it via VGA wire to the tv. I have configured the screen so the moment I connect the computer to the tv the monitor gets black so I work only with the tv screen. But after removing the VGA wire the netbook screen remains black. Sometimes it just needs time and I can see again the desktop. Others the screens remains black and I have to force a shut down.

This started a few weeks ago.

Anyone having the same problem?
