caut schema samsung 22f5470 main. eticheta BN97_07025p  ,main BN41-01957B ,eticheta ci+bn94-06485j

acest tv a venit cu un scurt in mainboard ic1601_ad un banal circuit integrat ca si capsula identic cu un 24cxx smd dar cu racire pe dedesupt,(posibil o sursa,un dual mosfet,cine stie)acest circuit avea capsula prajita nu se putea citi nimic de pe el,are si displayul crapat,dar arata bine si m-am gandit sa-l pun pe picioare,posibil sa fi fost alimentat gresit,are nevoie de sursa externa 14v

posibil tps54328dda?

va multumesc tuturor de intentie

se pare ca doar rusii au dezvoltat subiect pe acest mainboard,de 22 si 19 inch,si ic1601_ad este tps54328dda

am sa sap zilele aste in el si vad ce rezulta,sper sa nu am norocul rusului si sa fi fost trasnit,si tot mort a ramas dupa schimbare ic1601_ad

dar nu strica si schema daca o are cineva,ca cine stie ce ma asteapta

toate cele bune
