cum se mai poate reduce ditemperatura acestei piese ?din 3 buc am pus una la un tv ,la pornire se aude un sfarait dupa care inceteaza dar se incinge excesiv,am considerat ca mai are ceva si l-am dat deoparte.am trecut la altul cu acelasi defect si la acesta era imaginea bruiata ca si cum as fi pus un trz normal(daca ati incercat asta vreodata),am scos trz si l-am pus pe al treilea ,cu acesta functioneaza normal dar se cam incalzeste si am mai adaugat un mic radiator sa disipeze caldura mai bine.e prima data cand mi se intampla asa cu finalii linii cumparand din acelasi loc de mai mult timp(o persoana)deci revin la intrebare :se mai poate scade din temperatura?mentionez ca am scimbat conzii din baza :si cu 10 si cu 22 micro e acelasi lucru.
