TV Ryder 21R180 probleme pornire


Recommended Posts

Buna ziua!Acest tv cu sasiu Tousda TH-P1008 face urmatorul fenomen:Dau drumul se aprinde ledul rosu pornesc de la p+ ledul se face galben si se aude parca ar vrea sa porneasca inalta dar se aude un PRRRRRR si daca masor cu osciloscopul in bazalui BU nu sunt impulsuri bune.Dar daca las in proza mai mult timp dupa chinuiala atunci porneste tv si merge cateodata se intrerupe sonorul.Nu vad nici un condensator umflat iar tensiunile sunt 115V si restul in loc de 28V am 25V (asta cand e in faza de pornire) la baleiaj vertical am 9V respectiv -11V la audio am 12V.Nu stiu ce poate fi ,sa fie trafo linii sa fie procesorul?Astept idei .Va multumesc.
