Mariok Posted March 18, 2018 Author Report Share Posted March 18, 2018 Tranzistore ovi sto su na slici od njih je nastao crni dim na traci i vjerovatno je ako ne i sigurno glavni krivac za problem pa me zanima na koji nacin ih ispitat dali se moraju odlemit ili nemoraju?

giZ_Mo Posted March 18, 2018 Report Share Posted March 18, 2018 Пази само то што изгледају као транзистори нису, стабилизатори напона су. IC 801- 7815 IC 803 - 7915 IC 450 - 7805 IC 451 - 7812 Quote Link to comment Share on other sites More sharing options...
uzvarb Posted March 19, 2018 Report Share Posted March 19, 2018 Prvo proveri ima li loših lemova na elementima. Konkretno na "cipovima" pretpojacala, i ostalo. Quote Link to comment Share on other sites More sharing options...

Nije problem samo zameniti taj regulator, treba naći šta on napaja i zašto je pregoreo (vidi se i na štampi da se preterano grejao). Quote Link to comment Share on other sites More sharing options...
