salut,cu ceva timp in urma am achizitionat in urma unui schimb acest aparat.

la momentul respectiv la proba a fost ok(din cate imi amintesc) dar ieri dupa ce l-am curatat de praf in interior (am folosit si isopropilic)am constatat ca ceva tiuie in el(zona partii de amplificare),nu imi dau seama exact ce.

pe langa asta,pe iesirea pt subwoofer scoate curent(7-9v) iar iesirile din stanga(front si rear)au un zgomot de fond mare in difuzoare,semnalul auzindu-se f slab.care ar fi cauza si cu ce piese pot sa incep sa schimb.atasez cateva poze cu interiorul

In cazul asta treaba e mult mai complexa .Incearca sa urmaresti la intrare si la iesire (comparativ pe cele 2 ci ) cu o casca de impedanta mare .
