No backlight. LCD and sound functional

Hi all. I have a Panasonic Viera TH-L55DT5. When I power it up, the sound and LCD work fine, but the backlight (of led strips) doesn't light up at all. I have opened the back and checked the voltage on the PSU to the best of my ability, and it appears to be over 5 volts to the main board and around 2 to the inverter board. I'm not sure if I'm checking in the right places, though.
