LCD Sharp defect


Recommended Posts

Salutare la toti colegi

  Am acest lcd Sharp model LC-32SA1E, care are urmatorul sintom.La conectarea la retea ledul rosu se aprinde un pic ,dar cand apas butonul de pornire releul din lcd se aude cum actioneaza si ledul se stinge fara ca tv sa porneasca.Am facut cateva masuratori pe placa de alimentare si am constata ca diodele D728,D762 model ST03D170 nu masoara absolut nimik,ce fel de diode sunt? e normal sa nu masoare?

  Ceva idei pt rezolvarea acestui defect.Va multumesc
