No backlight, no display, has sound

Hello, I have a Sony XBR-55X850C and I have no backlight, no display but I do have sound.

ANSWERS:

Tyler Saboe  the backlight voltage seems a bit low. you’ve tried shining a flashlight beam at an angle to see if you can make out silhouettes etc.? If you do not then the issue is more likely the t-con board , main board and power board/backlight array last. Follow the flowsheet to see what you can find out.
