Sound but no display

Sound but no display

So I have a Vizio Model E470VA from 2011. There is sound but zero display. The backlight is fine from what I can tell all the boards look fine. I checked for burnt out components and none looked bad. I even took them all off to check the bottoms for signs off damage but nothing. All the cables look fine and I even tried replacing the power supply board and still nothing. Any ideas would be appreciated.
