Vas Posted January 12, 2012 Author Share Posted January 12, 2012 De trei ore caut pe Net,dar nimic nu gasesc.Sa nu existe nicaieri schema acestui invertor. Link to comment
nostrom Posted January 12, 2012 Share Posted January 12, 2012 De regula la acest inverter se defecteaza FDS8978 Link to comment
Vas Posted January 12, 2012 Author Share Posted January 12, 2012 Chiar si eu asta banuiesc,de asta caut schema.Cele doua mos-uri laterale arata suspect,dar asa de incalcita e placa,nu-mi dau seama daca se inchide circuitul prin alta parte,sau e in scurt mos-ul.Nu vreau sa dezlipesc de pe placa,sint tare sensibile la lipire.

Vas Posted January 24, 2012 Author Share Posted January 24, 2012 Revin cu acest LCD.Este sasiu Vestel 17MB12-2,alimentarea 17PW20.1,invertor 17INV03-1.A fost un FET dublu in invertor in scurt.Am inlocuit,la pornire se aprinde ledul de stand-by,porneste sursa de putere,apari tensiunile de 12v,24v,dupa care sursa decupleaza,si ramane in functiune sursa de stand-by,ledul lumineaza in continuare fara sa palpaie Link to comment
luk81 Posted March 5, 2012 Share Posted March 5, 2012 Daca nu ai rezolvat, verifica conexiunile la lampi(desfaci panoul). E posibil sa descarce la o lampa. Link to comment
