Salut colegii ! am in fata un televizor Samsung CRT model CZ-21F32T placa KS1A- AA-4100131G-SA proc TDA 9351PS/N2/3i0754 , cadre LA xxxx...ca nu se vede bine, sursa am gasit-o schimbata de altcineva ..... cert este ca scoate tensiunile de 110 V si 12 V . Am gasit ars integratul LA7632, cel care primeste 12 volti si scoate 3,3 V , 5V , 8V...power....si ce mai scoate el ! L-am schimbat, am masurat condensatorii de filtraje , mi-a plecat televizorul dar se incinge integratul de nu poti tine degetul pe radiator ! am dublat radiatorul....dar nu-i o solutie ! Rog si multumesc pentru orice parere !
