Philips 190s nu porneste

Recommended Posts

Este vorba de un monitor lcd philips 190s, care e complet mort. Nu se aprinde nici ledul stand-by.Cica dupa o pana de curent nu a mai mers.Diodele sunt bune, conzi arata bine, siguranta e buna.Dupa cum se vede, a mai incercat cineva sa-l repare, a inlocuit in sursa 47/50.Vreo idee?

Cum adica ai 220V pe condul de 400V ? Nu trebuie sa ai 310V acolo daca ala e filtrajul principal ?Daca e asa e condul uscat.

rezolvat cu ic controllerul din sursa, acum se aprinde o secunda ecranul si se stinge. O sa schimb conzi din secundar si revin.
