I bought a 2320 not working and when I received it there was no video internal or external. The LCD backlight comes on but no video. I replaced MB thinking video chip had gone bad. Now with new board I still have backlight on but no LCD, external monitor is working. If the controller board was bad wouldn't I not get back light. I did remove the touchscreen because of broken components but I don't see where that would affect anything. Any idea what to try next? Thanks Michael
