fabio09 Posted September 3, 2012 Share Posted September 3, 2012 va salut! Am o problema cu un tv nei ce ma chinuie de o saptămana şi nu-i dau de cap. Nu funcţioneaza sursa care are IC- TDA16846P. Şi anume:-pe pin 11 la ic= 2v.-pe pin 2=4v. -pe pin 14=4v.- rez de 1M si 3,9M inlocuite.IC si conzii inlocuiti. Cu IC original am aceleasi tensiuni. Desi am pus piese noi sursa nu funcţioneaza.are cineva vreo idee ce as mai putea face? Quote Link to comment Share on other sites More sharing options...

coman ion Posted September 3, 2012 Share Posted September 3, 2012 Dioda care face alimentarea lui tda16846 dupa pornire e ok? Quote Link to comment Share on other sites More sharing options...
dan-a2 Posted September 3, 2012 Share Posted September 3, 2012 Ati verificat si barele de tensiuni din secundar ? > daca sursa e in protectie ? Quote Link to comment Share on other sites More sharing options...
fabio09 Posted September 3, 2012 Author Share Posted September 3, 2012 e bun .am verificat tot...l-am primit defect... Quote Link to comment Share on other sites More sharing options...
naebv Posted September 3, 2012 Share Posted September 3, 2012 Posibil ca in secundar sa aveti consum marit...verificati daca aveti cca 310Vcc pe condensatorul de filtraj din sursa...sau inlocuiti trafo chopper. Quote Link to comment Share on other sites More sharing options...
fabio09 Posted September 6, 2012 Author Share Posted September 6, 2012 Am rezolvat....de fapt era defect integratul TDA16846P,... si cele care le-am pus noi erau tot defecte..va multumesc pentru sfaturi... Quote Link to comment Share on other sites More sharing options...
