chassis:3P66
UOC- TDA12156PS/N3/3/AK8 all voltage become 0 in 1 sec but when short Q605 collector & emitor 3.3v, 5.1v B+ standby 55v are ok. try to change uoc, eht, hot and w6553 related component but still no luck . please help me. |

alamgir80, check IC602 and D601. On the Q605 base submit 0 volts. |
||||
alamgir80 24/07/2012 21:09 |
Changed ic602 and Q601 nothing new. when put 0 in Q605 all volt(110v,46v,12v,12v) come for 1sec. |

alamgir80, darings of L602 also include. What does that change? IC601 4 pin how many tension? C607? |
||||
alamgir80 24/07/2012 21:55 |
After change L602, C607 same problem. and change all components related ic601. |

alamgir80, take your time. Announce a food IC601 4 pin. there should be about 12-18 volts and change breakthroughs. If there is no that or IC601 is faulty or C609 or R602 or R603 |
||||
alamgir80 24/07/2012 22:49 |
IC601 change 3 times and components change as you say, still same. |

alamgir80, IC601 structurally generator and power key. A generator food via R602 and R603 resistors. 4th pin of IC601. How many volt? |

alamgir80, эта проблема известна ещё с МП-3-3, когда подстроечник "гулял" или последовательно с ним резистор--2ком. |
||||
aze1959 25/07/2012 14:28 |
alamgir80, one of standard defects |

One big problem from "Chassis:3P66" reading firmware with ponyprog and IC-Prog. After write firmware with "ponyprog" and "IC-Prog" cannot strart TV. |

with this problem it is better to you to address to the person under a nickname of "key-s" to send it the personal message or to write on mail |

valya, ну так обматерили бы я не заметил |

Ну вы ребята даёте. Тут же почти все слова как русские. Вот только в слове start он сделал ошибку.
|
||||
aze1959 26/07/2012 14:14 |
может быть и так
на этом слове я тоже "спотыкнулся" и несколько неверно понял смысл написанного |
||||

After write with external eeprom copier no any problem.
But when write with ponyprog and ic-prog no result! It,s ponyprog and ic-progsoftware bug? or (chassis: 3P66) security ? |

Put the true that is not written down memory wait while the processor identifies it and will register and then come into service installations and manually establish. service I attach |
||||
alamgir80 26/07/2012 21:07 |
can start (chassis: 3P66) with blank memory ? |
||||
aze1959 26/07/2012 21:50 |
yes |
