It is completely inoperative, voltage of 5v with 5.1 and standby 2.8v. So I was suspicious of the 1.8 regulator, as it showed 1v at the output. | Ruins components: ec4 capacitor, 1.8v u5 regulator. | Solved just by replacing capacitor ec4, regulator 1.8v u5. | |

Stand-by LED is on, when you press power nothing happens. normal voltages of 13v b and 5v a and b. However, voltages b turn on and off while a remains stable | Ci hdmi (ic 1101) shorted or with faults preventing the TV from starting and triggering main board protection | Remove the CI and test the board again on the TV, if it works, replace the CI with a new one | Eletronica SV - Guaira PR |

The backlight does not come on, nor does it blink after replacing the complete LED panel, in addition to a defect in the LEDs, also in the power supply, probably the panel and LEDs caused an overload due to a short in one of the LEDs and the power supply failed. | I.c position ic9101 (7014x / 1449) smd in the secondary of the power supply, it switches the 02 fets that feed the LEDs and also the position transistor qm885 | I replaced it because I had scrap, but I don't know the correct nomenclature, without time to open a schematic. interesting in this project, because although the power supplies come out separately from the connector that goes to the LEDs, in fact in the power supply itself if you observe the rulers go in series from to to apr, tsound are 03 pairs of rulers... that is, 02 + 02 + 02 in series. | MIGUELTV |
