hey. i shipped my old keyboard, a 530, and in transit it got broken. now when you turn it on, all it does is the screen lights up and the speakers pop, but nothing appears on the screen. i tried opening it up, and all the connections look all right. so i have no clue. anyone have any ideas? thanks. zack

No offense please, but are you using the right ac adapter? When I got my 540, I thought I could use a multi setting ac adapter and I had the same problems you are having.
