bogdan546 Posted May 2, 2013 Author Share Posted May 2, 2013 revin iar cu aceasta sursa .A functionat pana acum dupa ce am inlocuit ncp-ul si acum iar nu mai functioneaza se aude sursa ca si cum ar fi in protectie (ticaie) si are toane cand scoate 5v (testata in gol) Am banuit ca ar fi ceva tot din controller si l-am inlocuit din nou dar nu s-a schimbat situatia banuiesc ca ar fi ceva din circuitul de reactie dar toate dau bune la masuratoare (optoculpor ,tranzistori smd ) Ar fi fost buna schema dar poate are cineva idee ce poate provoca defectul acesta Link to comment Share on other sites More sharing options...
Guest Posted May 2, 2013 Share Posted May 2, 2013 Ce treaba are ncp cu 5v?Acolo exista 2 surse independente si un pfc.Sursa cu ncp este forta pt lampi.Cu placa scoasa din tv se testeaza sursa auxiliara independent de cea cu ncp.Si asta in sarcina rezistiva.

Guest Posted May 2, 2013 Share Posted May 2, 2013 1--daca am o schema o dau cu placere,fara comentarii.2--asta am vrut sa scot in evidenta,ca nu este nevoie de schema.Sursa de stby este independenta si se trateaza ca o aplicatie a integratului mic de pe spate.Schema aproximativa se gaseste in pdf-ul integratului.
