Probleme potentiometru volum

Recommended Posts

Am luat o statie..ieftina ce-i drept dar cu problemele de rigoare.Bagata in priza nu produce "sunet".Finalii i-am verificat cu multimetrul, si imi arata o valoare intr-un anumit mod (nu stiu exact care-i combinatia pe care am aplicat-o dar stiu ca imi arata niste valori cand o "nimeresc" ) baza-colector-emitor.Stiu ca se pune in modul dioda si se verifica ori b-c, ori b-e etc.Acum...pontentiometrule rupt de la baza. iar ca sa verific efectiv "potentiometrul" tre sa dau jos placa de circuite in spatele fetei statiei.Vre-un alt sfat sau cum as putea sa-l repar fara sa-l dau jos? Cu ce as putea sa-l lipesc?Modelul statiei e pioneer sx-225Multumesc anticipat.
