Plug the unit in to an external monitor and see if displays there. If it does, that usually means there is a hardware problem. Since this unit appears to be a couple years old you would probably need to take it to a local technician to get looked at.
It definitely seems to be a hardware issue, you can have it go to a local technician and see about getting it repaired. I know that Acer has a standard repair fee of $199, if you'd like to take that avenue as well, and their repairs come with a 90 day repair warranty.
Own a Predator Laptop? Then I bet you have learned a thing or two from beststevie. He has been helping out in this forum for quite a while and it's about time we recognized him for it. Thanks beststevie!
