Salut,Nu am nici imagine nici sunet la tv mentionat (Lg CF-20D70X sasiu MC-64A).Ma gandesc sa inlocuiesc jungle TDA 8362B S7. Mai poate fi si altceva?Condensatorii par a fi buni.Multumesc.

Sursa este ok?scoate tensiuni?se alimenteaza liniile?Jungla asta are tensiune de alimentare sau de ce te-ai gandit sa schimbi direct jungla?

sursa e ok, iar tv are sunet...La inceput nu se vedea nimica dar umbland la reglajele din trafo, am mai deshis un pic imaginea dar tot intunecat se vede..

la sasiul acesta am gasit des lipitura rece la pinul de filament de pe trafo linii(heater) si astfel nu exista imagine.verificati daca filamentul se aprinde ferm si faceti ceva masuratori pt delimitarea defectului.verificati tensiunea pe grila 2 si soclul tubului.
