58l1350uc TV, backlight comes on for 1 second then goes out.

So the backlight goes out within a second of powering up. I have images on the screen with a flashlight test. I have 120v to each led strip (there are 5). So I'm not sure what's causing the LEDs to kick out right away. Even when the LEDs are off but tv is on I have 120 v at the LEDs. I'm a bit confused thank for your help in advance.
