TV without Standbay, has no secondary voltage, zener brand*(EA2) which is a short LT431 next to photoacoplator and CI PWM Burned | these components were replaced and was solved | Rodricell | |

Alloy with normal picture, it works for about 10 minutes then shuts down and flashing Sty 6x | The defect is relatively simple, the difficult is to fix. Defect: 3 burnt or short LEDs, but you can't find the LED bars anywsound to sell | Trying to replace the burnt LEDs from the LED bar, in my case it didn't work out because it ended up breaking the LED bar trail that is very thin | PEDRO IGOR |

When replacing LEDs and reducing chain, TV always turns on the first one by giving 53V, turning off in the control and turning again, rises to 63V (ideal). | In the 1k R2B9 resistor scheme, but comes with 10k, replace with 100k | replace resistance r2b9 or remove, device went back to work perfectly | Beto , eletrônica box 4 |

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 |
