I took apart the TV to check and examine the LED strips. I measured them with the multimeter in DIODE mode and some LED diodes were burned out (they didn't turn on and others did). I ordered a new LED strip but when I put it in, some LED diodes burned out again. I did a little online research and it turns out that this TV model has a common fault in its power supply in the part that feeds the backlight. From here on I need your help because I don't know much about this type of power supply. Thank you very much in advance.
