@ajcnfl you are not telling us if the clicking comes from the power board or from the main board. The values you are giving are pretty much what is expected. This could be a bad relay on the power board or a bad main board. REmember it is the mainboard that tells the power board to turn on etc. Post some pictures of your boards with your Question. That way we can see what you see.

@ajcnfl "Disconnected this cable" I assume you are referring to the one from the main board.All oif this"efore the TV went black, things started to act weird. Had to go in and clear memory and running apps" sound like a bad main board.

This
Power Supply BN44-00874E connector CNM802 to the Main Board BN94-14119C. Disconnected this cable, Have backlights now and the click noise stopped.
is correct behavior from the power board
This
Connected the cable back, clicking started and checked connector again. Pins 3-9 still 13V, Pin 2 now 0 to .24V, Pin 4 still 0V, Pin 6 now 0.04 to 0V, Pin 8 now 3.53V but changes to .11V when it clicks.
is what I would expect from a faulty main board.BUT check the solder connection of the relay. Something not right about this "3.53V but changes to .11V when it clicks."
"Does anyone know what I should be reading for an ohms measurement on the transistors" you'll need to measure all of those individually to their specs.
Post another picture of the power supply as large and clear as you can. the original you post is to small to enlarge and to check it. We need to see both sides of the board.
