Cześć,
proszę o pomoc w naprawie zasilacza LC Power 1800. Zasilacz nie uruchamia się po podłączeniu do testera. Z napięć na wtyczce 24 pin mam tylko +5VSB i PS-ON . Jeżeli chodzi o rezystancję to zauważyłem, że zwarta jest linia 12V (rezystancja 0,2ohm) pozostałe są ok. Przeglądnąłem zasilacz pod mikroskopem i nie zauważyłem spalonych elementów. Proszę o jakąś podpowiedź, gdzie ewentualnie mogę szukać tego zwarcia. Poniżej dołączam zdjęcia zasilacza. Uprzedzając ewentualne pytania na zdjęciach widać wylutowny duży kondensator i dwa tranzystory, które usunąłem celem sprawdzenia(okazały się dobre).

Hello!

Check the highlighted four components in the following picture. They are probably dual diodes in single package.

Dzięki za podpowiedź. Okazało się, zwarty był jeden z mosfetów, które zaznaczyłeś na zdjęciu po wymianie zasilacz działa.
