In our lab, we have a 5071B and the LCD screen doesn't works. It is ilimunated, but it just "print" black, and the touch screen works. Currently we are using the 5071B with an external monitor screen.
When we go to the windows graphic options it just detects and shows the external monitor data. We think it is due to a driver problem.
Anyone knows what we have to do to be able to use the LCD screen?
