Witam,
mam w naprawie zasilacz jak w temacie. Sprzęt nie startuje po podłączeni zasilania(sprawdzam na testerze do zasilaczy). Są napięcia:
PS_ON 2,5V
+5VSB 5V
Sprawdziłem wszystkie tranzystory i diody w poszukiwaniu zwarcia ale nic nie znalazłem. Pomierzyłem kondensatory po stronie pierwotnej i też są ok. Brak zwarć na liniach 3,5 i12V. Sprawdzałem też pod termowizją i nie zauważyłem nic niepokojącego.
Proszę o pomoc bo już nie mam pomysłów.

Hello!

The resistor R30 seems suspicious. Check, if it's not damaged.

Rezystor okazał się uszkodzony. Po wymianie na sprawny wszystko działa. Sprawdzałem zasilacz pod mikroskopem go przeoczyłem.
Wielkie dzięki!!!
