a venit cu defectul: are sonor, nu se aprinde display-ul

problema banuiesc sa fie pe invertor, mai precis pe OZ960GN.

am verificat alimentarea invertorului, exista 12v, siguranta este buna, mosfetii(4buc P2503NVG) sunt buni

pe pin 5(vdd) al oz960gn am 5,4v

cum pot anula protectia, sa vad daca se aprind lampile?

Posibil o lampa defecta . Cauta sa deconectezi lampile din panel , si conecteaza altele in afara panelului , sa vezi daca se aprind . Oz960 primeste comanda on de la mainboard ?

am rezolvat problema; defectul a fost dat de sursa (externa, capsulata), nicidecum de invertor

avea 12v, dar nu avea amperajul necesar

avand o sursa in laborator de 12v6a am conectat-o si s-a aprins tv-ul

am decapsulat sursa si am gasit 2 conzi de 1000uf16v bombati; i-am schimbat, plus unul din primar de 47uf35v, toti la 105 grade, samhva!
