Va salut.Am nevoie de parerea d-voastra ptr. a-mi infirma sau confima banuiala defectarii trafo linii la acest tv. La pornire ledul i-mi trece pe verde ,b-ul ramane corect ,dar fara impulsuri de pornire a liniilor.jungla se alimenteaza corect cu cei 8v dar daca decuplez alimentare finalului linii regasesc in baza frecventa liniilor corecta care la alimentarea finalului aceasta dispare.Am verificat trafo cu testerul cu leduri iar acesta i-mi indica ca ar fi ok dar cred ca aici problema ar fi problema spliterului fit din trafo pe care testerul nu-l poate verifica.Rog daca am omis altceva de verificat sa mi se sugereze ce ar mai trebui verificat..

Defectul este echivalent cu cel de la 11ak30 cu cond de 100nF. Cauta reactia de la traful linii la STV pt sincro . Eu zic ca amplitudinea semnalului de sincro este luat drept semnal de alarma/ protectie.

Mai este si calea de ABL care opreste semnalul de linii. Daca este tub de 90^ scoate bobinele de deflexie si vezi daca se mai opreste comanda.
