Modul plasma Samsung

Recommended Posts

Buna ziua.Am primit o plasma Samsung la reparat care porneste 3 secunde arata un ecran cu cateva liniii apoi ecranu se intuneca si ciclul se reia la nesfarsit.Dupa ce am demontat-o am gasit siguranta de pr modul X-MAIN cu codul:LJ41-03438A arsa.La verificari cei 4 tranzistori IXGQ85N33PCD1 sant in scurt circuit,si o dioda STTH40P03S este sarita o bucata din ea.Fara modulul x-main am aceasi manifestare..Am o intrebare cele 2 pamblici care ies din modul si se duc in display au rezistenta ohmica 0 intre ele..Este normal acest lucru?sau este posibil sa mai fie si altceva defect?Tensiunile le-am masurat si sant conforme cu ceea ce scrie pe etichetele displayului..As cumpara un modul insa nu stiu cum sa verific daca restul este bun,pe modulul Y-MAIN sigurantele sant bune si la masuratori nu am gasit altceva defect.Va multumesc anticipat..
