mercenarx Posted December 28, 2018 Author Share Posted December 28, 2018 multumesc iuliantv , bun linkul asta! acuma , eu si cu limba rusa nu suntem prieteni , dar am incercat cu google translate si traducerea este asa : LED-ul de la ieșirea 14 la sol (original in rusa : BD9882F Светодиод с 14-го вывода на массу. ) am inteles corect , trebuie montat un led intre pin 14 si masa? si inca ceva : la mine pe placa am BD9882 , si nu BD9882F. este acelasi lucru ?

mercenarx Posted January 9, 2019 Author Share Posted January 9, 2019 "La Multi Ani !" pe 2019 , tuturor colegilor forumisti !! am revenit cu tv-ul asta , care n-a functionat decat 2 zile cu A_DIM scos din circuit .. acum , face absolut la fel : porneste , apare imaginea si sonorul pentru o fractiune de secunda , si se pune in st-by (lipsa toate tensiunile din secundar). daca scot din circuit si BL_ON/OFF (pin 12 mufa PL802) , sursa nu mai intra in st-by , insa evident nu mai apare nici imaginea (lipsa backlight) in functionare normala in BL_ON/OFF erau 3,3 volti (veneau din placa main) am aplicat in pin 12 de la mufa PL802 3,3 volti din sursa externa , dar se pune deasemenea sursa in st-by (firul l-am deconectat de la mainboard) cred ca este consumul marit pe bara de 24 volti , alta idee are cineva ? multumesc!

iuliantv Posted January 9, 2019 Share Posted January 9, 2019 (edited) sa nu fie defect in sursa in pfc,in poza de mai jos am incercuit cu rosu doi condesatori ce fac figuri si dau asemenea defecte(,100nf parca )2 buc identice Edited January 9, 2019 by iuliantv Quote Link to comment Share on other sites More sharing options...
mercenarx Posted January 9, 2019 Author Share Posted January 9, 2019 (edited) mai exact care sunt conzii (nu pot sa o maresc) am 395 volti ( si in st-by), dar voi verifica conzii respectiv initial , am gasit umflati 3 condensatori in secundar (c806, c851 si c818) ,posibil sa mai fie si altii cu defect , mersi de raspuns!

iuliantv Posted January 9, 2019 Share Posted January 9, 2019 eu stiu ca pfc-ul lucreaza cand tv-ul iese din stby,deci cu el pornit trebuie sa fie acei 395v Quote Link to comment Share on other sites More sharing options...
mercenarx Posted January 9, 2019 Author Share Posted January 9, 2019 in st-by sunt 280 de volti , am gresit eu.. acei 2 conzi sunt de 15nF/630V . daca am ii schimb. Quote Link to comment Share on other sites More sharing options...
Gabriel_S Posted January 9, 2019 Share Posted January 9, 2019 Condensatorii aia trebuiau schimbați înainte te sa dați shield-ul jos de pe invertor. 24 v sta fix? Quote Link to comment Share on other sites More sharing options...
