Tv was admitted, coming from another assistance wsound the t-con.tv board had been condemned to be completely inoperative! When opening, I disconnected the flat (pci main/t-con) and the TV turned on, tsound was sound but, of course, no image. the t-con fuse was open, when replacing it, it burned again... carrying out a quick visual inspection and continuity test on the smd capacitors, I checked the capacitor in position c31, in the dc/dc circuit (t-con ) shorted. | I removed the capacitor and replaced the fuse. The TV turned on again and had no problems. I chose to leave it without the capacitor under test and it continued to work perfectly until delivery to the customer. A big hug to everyone and don't forget to post repair tips, this is one of the best tools for the technician! | Removal of capacitor c31 on the t-con board (dc/dc power supply), shorted smd. circuit worked fine without it! | AnisioH |

Device does not change polarization | Q100 and 102 a1281 open. | Q100 cannot be the bf423 as some colleagues are indicating, as the lnbf output is only 9v and the q102 can be placed as tip42 or tip42c. the q100 must be placed the bd135 or the original 2sa1281. | Jailson Lima |

Does not turn on LED decreases brightness and lights up again | When connecting the cable to the network, the LED lights up and decreases in brightness as if it were blinking and the TV does not start, measuring the power supply voltages d807 +b 103v with 80v oscillating downwards and d808 +b 16v with 6v and oscillating downwards. After analyzing the entire power supply, I found a 1u x 100v capacitor c824 exhausted. I'm sending it because I can't find any advice on this in any forum. | Matões A. Técnica | |

It wouldn't open the disk access cover or turn on or give any signal | After testing the power supply, a short was found in the controller; faults were found in the power and open/close buttons on the deck and the rubber that moves the disc tray was broken. | Replaced everything and it works perfect again! | Jailson Lima |

When plugged into the socket it gives just an oscillation as when it turns on and the stand by does not light up; Turning it on and off several times, sometimes it turns on, and when you turn it off, it doesn't turn on again. Sometimes it even felt like cold welding, out of nowsound the standby would come on but then go off. | When analyzing the power supply, I didn't find any damage to any component, but when testing the d802, I found a current leak and the standby LED came on after replacing it with an FR05 diode, but the TV still didn't always turn on when pressing the power button, So I also replaced the d810 with the same one and it worked perfectly. | Replace the components mentioned and move on to another device. | Jailson Lima |
