Tv Philips sasiu L9.2e

Recommended Posts

La acest tv porneste sursa,led rosu aprins,B+-94v,celelalte tensiuni ok.Daca dau comanda on led-ul palpaie si nu porneste tv-ul,B+ ramane 94-95v iar celelalte tensiuni ale sursei pulseaza 2-3v in minus fata de tensiunile normale.Schimbat un pumn de condensatori din primarul si secundarul sursei cat si din tensiunile recuperate din trafo linii dar defectul se incapataneaza sa ramana acelasi.Nu mai am idei ce sa mai schimb si va cer ajutorul.multumesc

Led-ul palpaie pana opresc alimentarea.Am scos final linii din montaj si am pus bec C-E.La pornire din butonul de retea toate tensiunile sunt ok dar daca dau comanda on doar B+ mai ramane ok,restul tensiunilor o iau razna si palpaie led-ul
