Va rogun sfat pt. acest defect ca mi-a scos peri albi .Odata deconectat de la retea mai mult timp (o ora sa zicem) la repornire ledul se aprinde direct in verde dar inalta nu porneste , tensiunile sunt ok mai putin cea de 11v care este scazuta la 8,4v.Dupa 5-10 min ledul trece pe rosu tensiunea devine normala (11v) iar tv-ul poate fi pornit din telecomanda si functioneaza normal fara ase mai opri .Am verificat si scimbat tot ce are legatura cu bara de 11v :cond. surse , diode ,optocuplorul,tiristorul.Am schimbat toti electrolitici atat din primarul sursei cat si din secundar si cei de pe recuperate . Am refacut toate lipiturile care m-i sau parut suspecte .Dati-mi macar o idee pe unde sa mai fac sapaturi .Multumesc!
