240V, that sounds like you have no load (LED strings has open circuit). As you can see, the filter cap C955 for the Boost converter circuit is only rated at 250VDC (33uF), so 240V is pushing it.
You need one of this:

So the question is; buy a tester (that will likely only be used once) for the cost of a set of LED strings, or just buy the LED strings...

Well, you will have to disassemble the panel to verify the exact type of LED strips you have (you have look up the LCD panel model number of your panel), it can also be bad connectors between the strips.
I do not know if your panel is edge-lit or back-lit.

You should start a new thread with make and model for the name of the thread and you must provide good clear pictures of the whole backside of the TV showing all the boards and good straight shot top and bottom side of the board, pictures must be clear enough to read the connector pins labels.
It looks like you count the pins wrong so those Voltages are not correct.
