Turn on and enter protection, turning off and flashing 6x red LED. First to do is check the LED bus. In my case all LEDs were ok.Unique way of making it no protection was putting a 1mega resistor between Pins 3 and 37 of CI BD9422, monitoring the voltage in pin 3 needs to have around 1.5V so as not to protectZW ELETRONICA

Alloy with normal picture, it works for about 10 minutes then shuts down and flashing Sty 6xThe defect is relatively simple, the difficult is to fix. Defect: 3 burnt or short LEDs, but you can't find the LED bars anywsound to sellTrying to replace the burnt LEDs from the LED bar, in my case it didn't work out because it ended up breaking the LED bar trail that is very thinPEDRO IGOR

No backlight, flashes 6x standbay and shuts downI removed the screen and checked all LED connections everything was all right anyway jampi all connections to ensure and did not solve. I replaced the large capacitor that feeds the LEDs next to the LED controller CI and nothing. Anyway it was CI BD9397EFV. To test the return of LEDs with oscilloscopeRodrigo
