Hey, so my tv doesn't turn on the LEDs when I turn it on. If I put a flash light on the screen I see image, so I know that screen is good, Also hear sound. I dissemble the tv to check if LEDs works, I try them and they work fine. Just doesn't turn on while the rest of the tv does. Can anyone help me to fix it?

@nicolasrossi you are not telling us if you checked LED strips or each LED individually. This "I put a flash light on the screen I see image" is a pretty good indication that it is your backlight. You will need to measure the voltages from the mainboard to the power board. Check on CN9102/CN9203 and see if you have all those voltages. Those are DC voltages and you will have to have your TV turned on of course. If you have all those voltages then the issue "could" be the power board, but this will really depend on how you tested the backlight strips. Those are still my number one suspects.

Thank you for your answer, I tested each led individually.
@nicolasrossi could still be the strips. Remember that this will depend on how they all fit together and the power they draw then. If the voltages to the power board are okay then you can measure the voltage on the LED connectors. See what it is with the LED strips connected and then measure without them being connected.
