Tv LCD portabil, JAGA 7"

Recommended Posts

Va salut.Am rugamintea daca ma puteti ajuta cu o schema pentru un Tv LCD portabil, JAGA 7" LCD TV Model: JRV7.Practic m-ar interesa transistorii din invertorul pentru lampa care s-au ars si nu stiu nimic despre ei. Ceia ce se mai poate distinge pe unul dintre transistori este DF si dedesuptul lui (DF) este RA (A cu minus deasupra literei). Trans. sunt tip SOT89.Ceva caracteristici daca stie cineva ceva despre acesti transistori SMD.Multumesc anticipat pentru eventualul raspuns pe care-l veti da.

Ce puteti sa-mi spuneti despre marcajul de pe aceste sit-uri fiindca am o mare nedumirire intre raspunsul Dvstra si ceia ce am gasit eu cautand aceste marcaje ptru smd-uri.

Multumesc inca o data ptr. raspunsuri.

PS. am incercat sa pun si un atasament cu foto al transistorului dar nu-mi permite postarea facand-umi trimitere la regulile forumului.
