Here is some more information about this problem with my SB500. I connected it up using an Ethernet cable. It behaves the same way although I do get the network light to come briefly. The "N" lights up and flashes briefly along with the network light which is solid. After a couple of minutes when the TV screen displays the press N on the remote to continue setup. both lights go out. The power light remains on. Basically, I am unable to get to the next screen. I have tried using the reset button on the back and the result is the same. Anybody got any ideas?
