Hi,

Do try installing the Toshiba Function key software if it's not working if your toggling the function keys to adjust the brightness. If that will not solve the problem do try a System Restore, restore it back to an earlier date or time before the problem even happened. Also uninstall/reinstall the graphics driver that may help as well in resolving the issue. Lastly, if all these will not work you may need to run a factory reset.

Here's the download link for Toshiba Function Key.
