those strips have a protection diode, have you already ruled out that they are bad?

you have to have a damaged led or an open line

Good morning friend Diego tlaa LED strips use two diodes in the voltage input to the power strip but in which those diodes light up do not measure either

Sanfalla already check each strip. What I want to know also what voltage has to go out for the blacklight?

at the power source on the black connector, the voltage next to the connector is labeled (on the printed) the voltage of each pin

Friend from experience we tell you that your fault is in the LEDs, sometimes they tend to cheat in the diagnosis, it may be that some are found resistive, short or open. The ic can detect certain variations and protect itself. Now, that TV seems to me to be 7 strips sectioned in 2 parts. Each strip must have 9 leds.
on the pins of connector 1 is ground and 4 are input voltages, swap the strips to confirm if any is wrong ....
but it is almost a fact that your fault is in the LEDs or protections.
Be very careful to cancel the protections.
