Cand a adus-o clientul,a spus ca s-a oprit in timpul functionarii; am bagat-o in priza, s-a aprins in modul demo, iar la apasarea butonului on a trecut in st-by, afisand ceasul.

Am desfacut-o si dupa masuratori, am ajuns la q210(fn1016) si q212(fo1016) in scurtcircuit b-c ambii tranzistori, siguranta pr201, precum si q219(k2723) pe care l-am inlocuit cu k2937, si d227(1n4148), sarma

Am schimbat cele enumerate mai sus, am mai facut masuratori la rece, nu am mai gasit nimic suspect, am alimentat si... nimic, nici led aprins, moarta total...

Zic, am gresit ceva... scot finalii, montez pe cei vechi,defecti, alimentez, se aprinde in modul demo!!!

Am alimentat fara cei 2 tranzistori, nu se aprinde... m-am blocat! ceva idei?
