It takes time to tune in and when it tunes later it runs out of sign | Do not tune | Com 1.2 v no c3705 replace seletronic | Fabio-ia |

Turn on and off with Dprotect | Had no feed on sound output | It was the short -on -the -short photo of the gun | |

Only one addendum to the previous tip: it was breaking my head. To kill if the buffer was really bad, I removed the plate from the place. The Y-SUS Osciled without the buffer and released the signal to the controller. | Good luck. | World TV - Sorocaba | |

After recovery in Y and Z plates, yet the 18V did not oscillate, tension died. | YDRVTP (buffer) plate with one of the chips AN16538a burned. | Chip or drive replace. | World TV - Sorocaba |

LG Plasma 42PC7R TV connects the reme and disarm. No tension vs and va. Rectifying !!! | Damaged power supply. She turns on, Arms the reme and disarms, flashing the green LED, so the LED comes back to red and remains turned off. When it is turned on, we have the 5V voltage on the power supply plate, but when the power is tight, the VA and VS tensions are falling, it is not even zero, but when it arms the reme, the 190V VS voltage appears quickly and falls to zero, that happens with VS, also happens with 12V, 19V, 3.4V, I already tested the power supply, I already tested the power supply Connected in energy, without any connected exit, and so does my theory that as I are not being generated the others are protected. I checked the VA line and found nothing short, the reference sectors I lifted all resistors and scraped the glue, because in some cases, with time the glue drives and throws in protection, but the defect persisted after removing glue under the components. The CI Q801 is not short, but is replaced in conduct, at first it is responsible for the 190V vs tension. | PFC TBM I replaced C603 (450V 270UF), R632, R633, R634 of 250k each. replace of Q801 (KTC3198) for a BC547 reordering the order of pins attention to this. I took the C802 (471 1KV) disk ceramic capacitor. SOLVED !!! | Adriel |

Bind | Measuring outputs at P201 found 2V at the 6V power supply. Not found integrated from the sector for sale, made adaptation using 7806 regulator with 12V entry of the power supply generating the 6V on the output to the main. Adapted dissipping on the chassis and resolved. | Remembering to interrupt original feeding and use only the one generated by the regulator *sir poo your angels sound | |
