Tv led sankey

Good afternoon I have a sankey led tv modeled cled32ao3 that came with the fault that did not turn on, the tests were carried out to determine the fault and it was concluded that it was the feedback stage that did not start. The screen presents perfect image and audio, we checked the LEDs and to my surprise all absolutely all 18 LEDs were burned. which is strange given that in our experience there are always two or three damaged. The LEDs were replaced by the required 3.6 volts, the TV started well, each LED reaches 3.4 volts, but with the problem that does not turn off, When you connect the TV to the power outlet, turn on the LEDs at once. By powering the TV, it turns on normal image and audio. When giving power, the image or audio is turned off but the LEDs are still on. the input voltage to the leds is 22.4 volts

Probably this TV came with that factory failure since it is not possible to realize, with everything packed it is not noticeable that the LEDs are on if the screen has no information. I think it's my explanation that all the LEDs have burned

the LEDs must be managed by an ic driver check that is not short-circuited or seeks and release its protection to see if you can turn off the LEDs
