Recommended Posts

-De cateva zile nu mai functioneaza Stereo pe FM si nu se mai amprind nici martorii de tuned si FM stereo (desi au fost verificati si functioneaza, inclusiv legatura la antena) - pe AM functioneaza corect, se aprinde ledul, receptia si acordare se face corect- Asadar defect doar pe FM...pe modul de cautare automat nu se mai face acordul pe posturi, desi functioneaza cautarea manuala (semnalul este mono, martorii stinsi)- nu am manaul la el si nici schema, am cautat insa nu am gasit- in interior am identificat urmatoarele CIic1 = LA1265ic2 = AN7470ic3 = TC9157APic4 = TD6104PRog pe cei care au intampinat astfel de probleme sa-mi dea o mana de ajutor multumesc anticipat!
