TV Nei sasiu Indiana200

Recommended Posts

Va rog daca poate cineva sa ma ajute cu un sfat ,pentru a reusi sa gasesc defectul acestui tv...Tensiunile in secundar sun bune ... la pornirea din telecomanda ledul isi schimba intensitatea si incepe sa clipeasca , in acelasi timp se aude in trafo linii un ticanic ca si cand ar pornii liniile , sunetul se aude in acelasi ritm in care clipeste si ledul ...Am observat ca in acel moment scad si tensiuniile in secundar B+ FIIND DE 80V Am inlocuit traful de linii , crezand ca e defect ... si TOTI Condensatorii din primar si secundar ... am mai inlociut si LM317 inpreuna condensatorii lui !!

Schimba integratul din primar.....este acolo un c de 1uf cu + la masa, sper ca l-ai pus bine.

nu cumva baraie si difuzorul,se incinge si finalul linii,traful de linii 98%
a facut mentiunea ca a inlocuit trf. de linii dar nu a specificat daca este nou sau sh (la sh netestat ce certitudine ai ca este bun)
