TV LG LCD 32LC2R

Recommended Posts

O schema pentru digitala de la acest tv? e15792594v-0 asa e notata.Tensiunea de 3.4 volti e constanta.Defectul tipic la acest tv sunt doi condensatori de 1000uf cu 10v si 680uf cu 10 care raspunde de furnizarea celor 3.4v pe digitala.Cel de 1000 umflat cel de 680 devalorizat.Dupa schimbarea lor tensiunea de 3.4 v constanta am doua diode pe dgitala cu led rosu si verde care nu se masoara cum trebuie.Nu imi dau seama ce diode sunt,dupa notatia pe placa sunt diode.Am sunet, am lumina in lampi dar nu am imagine.
