SEBYKO_76 Posted September 17, 2010 Share Posted September 17, 2010 Buna ziua..Am un monitor LCD SAMSUNG Model 920N defect...Ledul de st-by se stinge dupa cateva secunde de functionare (sursa nu functioneaza normal)...se aprinde din nou si fenomenul se repeta....Am verificat tensiunea de 12V si cea de 5V, am constatat ca se reduc,in ritmul stingerii ledului...Banuiesc a fi sursa defecta..., sau poate un consum marit la invertoare???? Am primit de la cineva o schema pe forum , dar pare ca nu corespunde....M-ar interesa o schema , daca are cineva....Poate si o parere despre acest defect...Multumesc anticipat.... Link to comment

BUGHIU Posted September 20, 2010 Share Posted September 20, 2010 Nu incerci ,daca este sursa ,cu o sursa UPS001? Link to comment
marinescug Posted September 25, 2010 Share Posted September 25, 2010 Pentru a scapa de banuiala ca e sau nu e sursa, incearca sa-l alimentezi dintr-o sursa de PC sau sa scoti sursa din monitor si sa-i pui ceva becuri pe ea. Link to comment
SHONELU Posted September 29, 2010 Share Posted September 29, 2010 Verifica si schimba mai intai condensatorii din sursa cu altii de calitate si la 105 gr. Link to comment
