Turns on the backlight, the LED is green, but without an image on the display, all voltages are normal, including the dcom. | Clean the display's flat cable on both sides, clean the board with thinner and then reflow the display's dcom board. | Amarildo Callai | |

When turning on the Stanby LED TV, it goes from white to green for a few seconds. At that moment the baklight comes on and the image appears for a few seconds as well. The TV turns off and the standby LED flashes 6x constantly, going into protection. TV controls are blocked. Just turn it off by pulling the plug from the socket. | Baklight protection circuit on the LD board/LD HM2 board with a problem. the ld_err line on the cn1000 connector was 1.26v when it should have been 0v. Checking continuity with a multimeter, I discovered that this line reaches an SMD NPN transistor located above the IC2000. Tsound was a shorted ceramic capacitor next to this transistor, preventing it from saturating and changing the voltage from 1.26v to 0v. | Replace the capacitor with a suitable one and the TV started working normally again. We can confuse it with a LED defect, or, worse, condemn the screen. | IZEletrônica |

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. | ||
