Dodavanje back light na tastaturu telefona *RESENO*

Post by stojkePN » 26 Sep 2012, 06:52

Radi se o mom bezicnom telefonu. Otvorio sam da ga ocistim pa vidim providna tastatura, a ima i mesta za led diode. Skinuo semu i propratio. Na ploci je falio tranzistor Q7, otpornik R15 i dodao Led diode i to radi super :lala: Tranzistor sam pozajmio sa pozicije Q8 jer je isti i vratio tako da mi fali jedan. Originalna oznaka je PSVTDTC143X. Sta mogu da stavim kao njegovu zamenu :?:

Nisam uspeo da nadjem na plocama od video rekordera ali nema veze. Napravio sam od smd tranzistora i 2 otpornika i to radi.
