LG sasiu MC84A


Recommended Posts

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 .

Am deconectat BV TDA8359J si tot asa se manifesta , posibil sa fi venit descarcarea pe antena si sa fi afectat TDA8842 ? Multumesc .

e posibil orice cand e traznit . e bine daca ai avea unul deja in rezerva nu sa-l cumperi pt. a face proba.
