Buna 

 

Am un tv samsung cu sursa BN4400199 care porneste 3 secunde  (are imagine si sunet ) dupa care se opreste iluminatul banuiesc ca am vre-un tub ccfl defect .intrebarea este cum pot sa dezactivez protectia la integratul LX1692 pentru a vedea care tub este cu probleme .

Sursa  main- ul si invertorul  a fost schimbat si incercat de la un tv functional deci exclus sa fie defecte . 

 

multumesc
