stefank Posted July 6, 2009 Share Posted July 6, 2009 Buna ziua , acest LG aflat in stand-by a avut parte de descarcari electrice care dupa spusele proprietarului a venit pe alimentare ( ? ) , in aceasta faza el porneste pt. o secunda , se aude pornirea inaltei , tensiunile secundare din traful de linii apar pt. 1 sec. dupa care intra in stand-by , la apasarea P+ sau din telecomanda porneste din nou pt. 1 secunda si revine in st-by . Tensiunile debitate de sursa sint corespunzatoare ( pe bara de 115 V am testat cu bec ) . Sursa este cu STRF6654 , procesorul este SDA5555-A007 , jungla TDA8842 . Multumesc pt. orice idee in rezolvarea problemei . Quote Link to comment Share on other sites More sharing options...

stefank Posted July 6, 2009 Author Share Posted July 6, 2009 Am deconectat BV TDA8359J si tot asa se manifesta , posibil sa fi venit descarcarea pe antena si sa fi afectat TDA8842 ? Multumesc . Quote Link to comment Share on other sites More sharing options...

stefank Posted July 7, 2009 Author Share Posted July 7, 2009 Am avut in stoc TDA8842 dar schimbarea nu a adus nici o " schimbare " , aveti cumva un dump pt. acest sasiu ? Multumesc . Quote Link to comment Share on other sites More sharing options...
tehtronics Posted July 7, 2009 Share Posted July 7, 2009 din cate imi amintesc merge si cu memorie goala (cu FF peste tot) Quote Link to comment Share on other sites More sharing options...
t-daniel Posted July 7, 2009 Share Posted July 7, 2009 Am reparat mai demult un sharp care se manifesta exact asa si nu a pornit decat dupa inlocuirea BV. TV-ul decedase in urma unor descarcari la trasformatorul de linii. Quote Link to comment Share on other sites More sharing options...
