Help troubleshooting the flaw in a Hisense

Last month, the building next to mine got rid of this giant plasma: A Hisense 60R6E-G181595-60N3500UWR. From the outside it looked intact and so I decided to make it my next project. When I plug it in, the screen turns on - there is no menu or logo, but I can hear the options clicking when I toggle the button.
