Va salut!

Sasiu pc04a defect initial desincronizare pe verticala ,dupa ce am rememediat defectul a disparut sonorul ,etajul final audio functioneaza corect am verificat condensatorii din el cit si cei din preamplificator  pe pin 4 tba120 sunt 5,3v si pin 5 3,5v .

Pe pin 11am 12v  ,imaginea este normala  vol + si vol- se vede ca actioneaza ce ar putea fi defect?
