Daca fuge de pe posta poate fi ori CAFul dereglat ori tunerul dus.Depanarea se incearca in ordinea asta.

C -ul cu care bobina de caf face acordul este devalorizat. Se afla fizic sub bobina si se inlocuieste cu un alt c montat intre terminalele bobinei pe spatele placii. Valoare intre 44-46 pf. sau un trimer de 15-45pf. Apoi acord fin al bobinei in timp ce faci cautarea programelor pana cand se stabilizeaza pe fiecare canal in parte cu imaginea cea mai buna.Spor la treaba!La inceput e chin ,apoi doar rutina.
