LED standbay blinks and but doesn't start | 5 Volts varying when it is connected from the motherboard, but disconnect it stabilizes at the power supply. The villas get 3 and 5V without being connected from the motherboard. I found capacitors without low capacitance but did not solve | I replaced the kia 431a for the TL431 in the ZDTB851 position and went back to work perfectly | Eletrônica M.F |

No picture, with sound. | SMD 125V/7A (F102) Open and CI 4614B (Q310) | replace CI and replace fuse, Note. (Redo the weld of all jumpers OOO resistor of the plate), including those that marked heating under the plate, as they are the causes of CI burn with cold welding increasing the tension over the CI. | Wortec |

It turns on, lights Stanby, when tightening Power replaces green and nothing happens, then blinks error 7 in the power supply LED. | High tension T1 at the power supply, after suffering to the damn, as it takes the stroke to test another I already visualized the charred winding at one point of the traf. | replace T1 (MIP320g-a-T1/TLT-2796) of the MIP320G-HV0 power supply. Explaining line of reasoning: the 5 volts and power on font appeared and also the 12 volt and 24 power supply appeared, but only the 5 volts and power on, so I suspected the stuff after putting one point of the multimeter at the exit of the trafa and I could see a small high voltage spark and that's wsound I suspected the tread, but the TV was not lumped, so I discarded, so In the end everything worked out. | MIGUELTV |

pictureless | Burnt led | replace of LED + Red bars. From I. replaced the 2R resistor with three 1R2 resistors in series, making 3R6, chain fell from 0.456ma to 257mA in film mode, in the other two picture modes, fell from 135m to 0.075ma. | Cesar762 |
