robert1000 Posted March 14, 2014 Share Posted March 14, 2014 Este vorba de un monitor lcd philips 190s, care e complet mort. Nu se aprinde nici ledul stand-by.Cica dupa o pana de curent nu a mai mers.Diodele sunt bune, conzi arata bine, siguranta e buna.Dupa cum se vede, a mai incercat cineva sa-l repare, a inlocuit in sursa 47/50.Vreo idee?

modoran Posted March 14, 2014 Share Posted March 14, 2014 Cum adica ai 220V pe condul de 400V ? Nu trebuie sa ai 310V acolo daca ala e filtrajul principal ?Daca e asa e condul uscat. Quote Link to comment Share on other sites More sharing options...
robert1000 Posted March 14, 2014 Author Share Posted March 14, 2014 L-am schimbat, acum am 275v. Nici o diferenta in functionare. Quote Link to comment Share on other sites More sharing options...
