I don't have a service manual for that set so I'm only able to help on a limited basis...Have you tried the flashlight test?...if the backlights are out then it could be a backlight driver board if it has one? or defective LEDs. See what you have for voltage going into the panel LED's

I have the same model TV that is 18 months old. The repairman wanted $365.00 to replace the inverter and update something on it. From what I have seen online, it is mainly just loose screws on the inverter. I called Sharp and they are paying for the repair on the TV
