Tv Beko cu sasiu E1 cu defect straniu...

Recommended Posts

Am pe masa un Beko de 37 cm sasiu E1 la care am acest defect. Am schimbat inclusiv integratul de cadre si toti electroliticii inclusiv refacut toate lipiturile la conzii in smd din jurul junglei. Defectul apare si dispare nu e stabil. Cand imaginea se muta in jos si apare o cursa inversa pe jumatatea imaginii sunetul incepe sa paraie. Aici aveti 2 poze cu defectul: www.tinypic.com/view.php?pic=be639e&s=9#.VtckfECCZW8 si a doua poza: http://tinypic.com/view.php?pic=2weanpv&s=9#.VtcjjkCCZW8 A mai intalnit cineva defectul asta?

Am verificat 3,3v si e ok. Am pus alt dump si defectul persista. Aveti alte idei?

Defect rezolvat cu succes!! Dioda zenner D501 de 15v, din pinii IN A si OUT A de la vertical defecta. La masuratoare arata bine,dar in circuit introduce cursa inversa cadre si muta rastrul in jos ca in fig. pe care le-am postat la deschiderea topic-ului. Multumesc tuturor pt. implicare!!
