Probleme cu invertorul la un Samsung 932mw

Recommended Posts

Simptome: lampile de sus se aprind; lampile de jos se aprind scurt cativa cm la capete, apoi invertorul se opreste.Lampile nu sunt problema , am pus altele de test si face la fel.Am scos trafo ridicator si masurat pare ok DAR secundarele masurate au rezistentele:secundar 1: 1280 ohm secundar 2: 1263 ohm; e cumva posibil ca secundarul 2 sa aiba ceva spire in scurt si asta sa fie problema? Partea ciudata e ca nu asta e cel care aprinde lampile de jos.Placa are codul SIP-1920, nu prea gasesc schema invertoruluiTrafo este TMS91429CT
