| SAMSUNG | UN40F5500AG | Does not turn on, just flashing standby (no backlight) | Without 13v power supply changed 10r resistor was measuring 4.22k next to the pfc capacitor | Replaced capacitor 10r fiz um video video... | Jean Vinicius Franco Lorenz |
| SAMSUNG | UN50TU7000G | Backlight off | Poor contact in the power supply board connector, | A direct connection was made from the power supply connector with wire to the LED bar connector, everything was fine | Fernando técnico |

| SAMSUNG | UN48J6300 | 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 |
| SAMSUNG | UN32EH4000 BN44-00492A | Nothing turns on, not even the standby LED | After analysis, the open fuse was identified in position fp801s, transistor mdf10n60 position qm802s and ci sk2n3 smd in position icm801s | Replace them and the TV will be back to 100% | Luiz Sena Eletrónica HYK |
