VIZIO E320i-B2 32" Backlight has gone out

I am 100% sure the backlight on my VIZIO E320i-B2 32" has gone out. Turned the lights off in room and used to flashlight at the screen and I can see the picture is on. Problem I am having is finding out what I need to replace. Do I need a backlight inverter board or does my model need something different? And if so what parts do I need?
