dan cod Posted April 11, 2014 Share Posted April 11, 2014 100% asta e problema lipseste tensiunea negativa la memorie.E o rezistenta si un cond care trebuiesc schimbate. Quote Link to comment Share on other sites More sharing options...
johnny79 Posted April 17, 2014 Share Posted April 17, 2014 Sau lipituri la mufe....placa cu procesorul si memoria este separata de restul ansamblului .....daca tensiunea de -30 V este prezenta,schimbati memoria....din cauza descarcarilor FIT se defecteaza.

validae Posted April 17, 2014 Share Posted April 17, 2014 Aceasi problema am avut-o cu un LG, am schimbat si memoria si degeaba.A fost nevoie sa schimb electroliticul de filtraj pe 8V si stabilizatorul de 5V si s-a rezolvat. Quote Link to comment Share on other sites More sharing options...
