It would seem a simple repair, restoration of the backlight ... however, these rulers drank my blood. The left half had a breakdown, in the left bar at the first LED (standing next to the connector), on a heat-removing aluminum substrate. The breakdown was about 10k and when the led-tester was connected, the line shone as if it were factory ... however, when installed in the TV case, it completely refused to turn on and made a clicking sound ... time was spent on finding and eliminating this byaka, but everything was restored and handed over to the owner.
P.S. the backlight current was reduced from 350mA to 200mA, but see how in the video ;)
