Hello and thanks for checking this out. I am totally to the world of Raspberry but I am thinking that I might have a dead board or I'm completely lost. I've connected the 7" element 14 touchscreen and a Pi 3b together and inserted a NOOBS card. As I understand things I should get some response when I power it up with a 5v 2amp supply. So far, no joy, just a black screen. The only LED turned on is one red LED near the power jack. I hope you might have a simple clue. Thanks
Larry
