Enter the service menu OF CHASSIS: UOC - LV762223 3C / LV762223 3E Memory - 24LC16B SMPS - STR-W6554A SAW - K7260 Vertical - LA78141 / STV9326 Sound - LA42102N Tuner - TAEA-G111D A / V Switch - LA72730 Tube - A51QGT420X FBT - BSC25-N0363 HOT - 2SC6093 / 2SC6090 RGB Amp. - 2SC3229 / 2SC2330 Remote: - MKJ54138901 / MKJ33981406 IC Remote - ADAM22C20P-020 My friends its very important problem regarding this slim Lg tv I have seen three tv in same fault. I have found short circuit horizontal out put transistor Now i replaced Transistor C6093 capacitor 183j 2000v 474j 400v 10uf 100v KA393 But when i trun it on again with 200w test lamp its short again . Fly back tranformer tested good. Any other friend encounter problem like this? ДОБАВЛЕНО 09/02/2013 03:37 Мои друзья ее очень важной проблемы относительно этого тонкий телевизор LG Я видел три телевизора в то же вине. Я нашел короткое замыкание горизонтальные из положить транзистора Теперь я заменил транзистор C6093 конденсатор 183j 2000V 474j 400v 10мкФ 100В KA393 Но когда я Трун его снова с 200W лампой испытание своей короткой снова. Летите обратно tranformer испытания хорошо. Любые другие проблемы встрече друга, как это? |

imran khan, What voltage of the feeding the Horizontal (+В) ?
ДОБАВЛЕНО 09/02/2013 22:21 imran khan, The Quality replaced C6093 real? |
| imran khan 10/02/2013 01:51 |
main B+110 volts feed horizontal C6093 is real.
Its brun 6 transistor in a raw I replace 183J 2000v but no help. |
| iv-9 10/02/2013 04:22 |
Try with other analogue of HOT or C6093 from other party. |

Photo points shows by mark red i have tested before. Now i am going to replace all parts in Hot section. |

imran khan, The Breakaway of the chains declining systems?
R403, С404 тest or(and) change . |
| imran khan 10/02/2013 18:41 |
O.k today i will do this |
| iv-9 10/02/2013 19:48 |
Куда он лампу втыкает? Если в разрыв цепи +B, то не должны HOT сгорать. И как FBT проверял? И что, на трех ТВ прямо один в один дефекты? Разговор слепого с глухим  |

скорее всего у него не работает нижний кондер диодного модулятора

Sorry for late reply
I have lost internet connection to the main server. Now i let you know that i did what you all said but still not fix the problem.
