bubusmecherul Posted January 17, 2012 Author Share Posted January 17, 2012 am scos tranzistorul de pe sasiul ce este un c1026 si lam verficat si arata bun,sa precizez ca butoanele de p+ si p- nu le avea pe sasiu,si leam inlocuit cu altele,sa fie si din cauza lor oare!,si cred ca finalul linii nu primeste impulsuri,am mai schimbat si 2 condesatori c427 si c804,acum nu se mai aprinde ledul cand pornesc de la butonul de retea,ce se intampla Link to comment
