Image flickering, fading and drizzling after warming up | When opening the lid, it was found that the boards with the power components (power supply, ysus and zsus) were showing signs of overheating and tsound were many cold solders. | Resolders were carried out on the three plates. Some components such as resistors of more than 2W had to be removed, the terminals scraped to get solder. resolder everything. | Pixel Assist |

Display with crazy "00", the CD spins at high speed and does not read, the 2 transistors close to the optical unit connector boil | Faulty oscillator crystal, it oxidizes and breaks the terminals, 16.9344mhz. After the change, if the disc cannot be read, but the laser stays on, replace the two power transistors near the optical drive connector. | 16.9344mhz oscillator crystal and the two power transistors, close to the laser connector, (2sd882 and 2sb772) use bd 139 and 140 or tip 41 and 42 inverted. | Trendset |

Does not turn on standby, relay knocking does not light the LEDs and kills the voltages that go to the main board, giving the false impression that the defect is the main board wi-fi module or LED bar | Resolder the power supply board and check for broken tracks on the printed circuit using a magnifying glass or microscope. In my case, tsound were 2 broken tracks, like a micro crack, almost imperceptible with the magnifying glass, but which proved to be broken in the continuity test. | Resolder the entire power supply board and correct possible broken tracks | Melquisedeque Campinas SP 019988377105 |
