Nu prea ma pricep cu localizarea blocurilor dar zic ca e in secundar la sursa. Rez asta arsa are prima culoare rosu sau maro e cam arsa dar se vede ceva, este inseriata cu o rez de 100k. Rez asta arsa este conectata la colectorul lui but11af.Tv nu se aprinde. Se aprindea led de stand by si se auzea un ticait acuma nu se mai aude nimica si nici nu se mai aprinde ledu.Edit:Am gasit acuma final lini ars si un cond de 10uF/250v umflat

Langa tranzistorul BUT11 mai aveti un alt tranzistor(pnp) ,poate este 2SA1013 ,daca a mai fost schimbat;verificati ambele tranzistoare.Se prea poate ca rezistenta de care vorbiti sa nu fie arsa ci tranzistoarele. Cele doua formeaza un releu electronic pentru st-by!!Pe linga astea ,schimbati cei doi electrolitici (sper ca sant doi) din primar si verificati rezistentele,in special cele de valoare mare!!!Poate este buna schema de : Thomas TCB 061X!!!

Pai atunci descarcati schema ce v-am dat si ....la treaba!!! Fara acel tranzistor merge doar oprit/pornit din butonul de retea,deci NU e in regula!!!! :sparge:
