BCS-DVR1604HE-T
W rejestratorze po burzy przestał działać LAN.

Namierzyłem upalony R536 oraz "nadpalony" R535 (50kOhm). Nawiązując do tematu:
jaki-to-rezystor-t49737.html
nie jestem pewien ale założyłem rezystory 75Ohm w trochę mniejszej obudowie.
Pomiędzy nogami (nie pomiędzy masą a poszczególnymi nogami) n1 a n6 oraz n3 a n4 diody U71 mam zwarcie, po ściągnięciu układu zwarcie nadal występuję
Co mnie jeszcze zastanawia to to że pomiędzy masą a wszystkimi padami U71 mam przerwę.

Nie pomyślałeś o tym że transformatorek widoczny na fotce powoduje owo ,,zwarcie" ? Wystarczy sobie zerknąć w jakikolwiek schemat z układem karty sieciowej i zrozumiesz wówczas na czym to polega.
Po takim strzale obstawiam że układ który wymontowałeś też jest uszkodzony.
