Na uredjaju s linka ne radi napajanje (nadam se da je samo napajanje). Izvadio sam ga iz kucista. Trebam netkog tko mi moze prodati novo takvo ili popraviti starog.

Frendu sam popravi vrlo slicnu stvar. Antensko pojacalo. Otisao mu je samo FET. Probaj ga provjeriti.

Hm, ima MUR820 (SWITCHMODE Power Rectifier) i IRFBE30 (HEXFET). Nisam bas u stosu s elektronikom u zadnje vrijeme. Kak najjednostavnije ispitati (moze li bez odlemljivanja)?

Moze ali nisi siguran - osim ako je skroz kratki spoj. Cak i kad ga odlemis nije 100%.
