Salutare !Situatia e urmatoarea: sursa functioneaza pe bec fara probleme , toate tensiunile sunt corecte, am sincro H vizualizat in baza final linii OK; cand pun placa pe TV starteaza, LED-ul se stinge , sunetul functioneaza (e alimentat direct din sursa) dar nu functioneaza final linii (imi dispare sincro H).Am descoperit ca in pinul 12(safety) al IC701 , VDP31xxB, apare tensiunea de 5v care blocheaza Hout. Trafo linii a fost schimbat pentru ca cel vechi descarca la jug.Daca ati intalnit situatia si aveti sugestii , va rog frumos! O seara placuta!
