The TV came to me when it turned on and after inserting the antenna and generating an image a few seconds later it turned off and the red LED flashed 6 times (LED bus error), however after this problem was resolved it maintained the symptom, but it took a little longer to turn off . | Regarding the bus error, the solution is to replace the bars, regarding the fact that the same symptom persists, I discovered that pin 31 of the ic-bd9397efv is the pin that sends information to the CPU about malfunctions in the backlight, but it only does this after some time (until the capacitor is charged) and the solution is to add a resistor in parallel with the capacitor which makes it impossible to charge so that the fault data is not sent to the cpu. | ||
