Guest Posted October 18, 2012 Share Posted October 18, 2012 Daca pe d805 ai 3v verifica c833, c855, lm7805 chiar si d805 de altfel toate componentele de pe bara de14vPS: Celelalte tensiuni - 12v, 22v, 5v, 33v sunt stabile ??? Link to comment
adrian250786 Posted October 20, 2012 Author Share Posted October 20, 2012 am pus bec pe U1 cu bobina scoasa si a pornit, BU-ul este vinovat eu l-am dat afara si l-am masurat si comparat cu unul nou si ohm-metric aratau la fel dar in tensiune o lua razna MULTUMESC PT SFATURI(ORICUM CIUDAT DEFECT)ps:trebuia incercat de prima data cu becul,m-am cam grabit sa iau decizii Link to comment
Guest Posted October 21, 2012 Share Posted October 21, 2012 Pe viitor schimba bu808 cu 2sc5388. Majoritate bu808 de pe piata sunt contrafacute, stifturi. Link to comment
