Probleme sursa cu str w6750f

Recommended Posts

Salut, am o problema cu un TV Samsung cw-21z45n, gasit busita puntea de diode si NTC-ul NT801 (cel de pe alternativ la intrarea in punte) schimbat amandoua impreuna cu condensatorii din sursa cel de 47/63v si 4,7/63v. A functionat frumos fix 4 ore dupa care sa oprit fara sa arda nimic cel putin in urma verificarilor nu se "vede "nimic afectat.Tensiuni prezente 270v la punte si un 24 de volti banuiesc ca tensiunea de start a sursei.Recunosc e primul model de genul asta si sunt un pic "pierdut" in ea.Inclin sa cred ca este de vina STR-ul w6750f.O parere de la cineva care sa mai lovit de sursa asta e binevenita.Multumesc
