1.am verificat cu ohm metru transformatoarele invertoare si au ambele aceleasi valori.2.nici o lampa nu are probleme deoarece le-am verificat pe fiecare in parte conectand numa cate una si pornind monitorul.Dar nici o rezolvare se comporta la fel.Alte idei?

mentionez ca invertorul porneste si cu o lampa din cele 4 dar in aceleas conditii sta 2 secunde aprinsa lampa

pai asa face cand o lampa sau mai multe sunt defecte...sau deconectate.comanda on/off a invertorului se mentine si dupa alea 2 sec?

este clar ca nu ati inteles nimic.comanda on/off cat este in ambele cazuri?asta trebuia verificat prima data.ps: am postat aproape simultan :rade:
