1) TV is OFF.
2) Keep the black probe of the meter on the chassis GND.
3) Keep red probe of the meter on the first pin (top pin of the connector based on your picture: https://www.badcaps.net/forum/attach...5&d=1500943915) of the LED connector
4) Keep an eye on the meter and then turn the TV on, see how high the Voltage go up to and then wait for about 10 seconds to see how low it goes down to, record that reading. Turn the TV off.
5) Move the red probe down to the seconds wire and repeat the same test again. You will do that on all six LED wires.

BTW, what is the power board P/N? BM44-??????
