florinstancu Posted October 27, 2006 Author Share Posted October 27, 2006 Ledul palpaie de cateva ori si se opreste.Am schimbat condensatorii din sursa dar fara rezultat, am pus un bec anuland bobina dupa bara de 115v, tv face la fel.Daca insit din telecomanda sa-l pornesc am observat ca tensiunea de 115 scade pe la 60-70 volti.
