Ajutor depanare ecran Tv Lcd Daewoo LP32L2CR

Recommended Posts

Buna ziua. Acest tv pare sa functioneze, dar nu am imagine, doar lampile raman aprinse. Deoarece t-conul l-am inlocuit cu altul, banuiesc problema a fi la ecran. Exista vreun kit de reparatie pentru acest ecran?

Ecran LTA320AP02

T-con 320AP03C2LV0.1

Va multumesc.

Rectific, tensiunile le-am masurat doar in sursa si sunt ok.

Azi am avut timp de el si am observat ca tensiunea pe alimentare t-con este de 8,27V, daca scot mufa din t-con am pe mainboard 10,38V.

Problema pare la mainboard. Codul este SL-M10M / M10X

Sursa DLP-32FW

Daca are cineva vreo schema.

Pe mainboard , in apropiere de mufa spre t-con am gasit un tranzistor smd notat 110G2 nu se vede prea bine care are colectorul pe tensiunea de alimentare t con si care este in scurt baza colector.

Am eliminat tranzistorul si scurtul a disparut .Are notatia pe cablaj QC901.

Ce tranzistor sr putea fi.
