#1 Jaki to rezystor

Sprawa dotyczy rejestratora i nie działającej karty LAN.
Rezystory bezpośrednio połączone z układem U71 (jeśli się nie mylę będzie to transil)

Dla R536 po wylutowaniu miernik wskazuję przerwę natomiast R535 50k Ohm (ale nie jestem pewien czy obydwa są takie same i czy wskazania R535 są prawidłowe). Z rezystorów nie da się odczytać symbolu, są prawdopodobnie delikatnie nadpalone, wnioskuję że może tam był symbol 75R0 bo takich rezystorów jest sporo na płycie, ale to tylko moje domniemania.
