naetv Posted January 12, 2009 Share Posted January 12, 2009 Vezi daca merge asta(in afara de finl sunet) Link to comment
dan-a2 Posted January 12, 2009 Share Posted January 12, 2009 cred ca este tv3k ;cel putin partea audio seamana ;daca gasesti vreun final ars(sau finalii) verifica si sursa Link to comment
naetv Posted January 12, 2009 Share Posted January 12, 2009 Cred ca tv3k este ,depinde cu ce este prevazut pentru prelucrarea sunetului stereo.Pare ca cea de Ivory este un tv3k mono ,pina si notatia componentelor este aceeasi. Link to comment
zvasile Posted January 12, 2009 Author Share Posted January 12, 2009 daca pun degetul pe pinii la f.audio se aude sunetul foarte slab Link to comment
HORIACN Posted January 12, 2009 Share Posted January 12, 2009 daca pun degetul pe pini la f.audio se aude sunetul foarte slab,posibil sa fie AN5265 finali Link to comment

dan-a2 Posted January 12, 2009 Share Posted January 12, 2009 daca nu ai 12v pe pin 1 verifica intre bara de 18v si pinul 1 trz. q425 ,dioda d410 si piesele aferente Link to comment
