1. Corrente ba BL laiha no
2. Led rasik balun kotu
Atu detalho ita bele hara ida por ida :
1. Corrente ba BL laiha
Corrente ba BL laiha ita bele cek ni-nian driver BL mak ho ic OB3350CP bele hare iha imagem tuir mai

Atu hare nia ne'e sei diak ita bele koko corrente ho tester ho karakter bainhira daun tester halai depois fila fali ho neneik signifika driver sei diak, maibe keta haluha mos chek ho capasitor sira iha parte driver BL
