yung item no. 47 naka-set sa "0",  item no. 80 (volume control) = 110, item no. 83 (sifsw) = "1", item no. 86 ="0" ,  88 (audio monitor sw, monitor or fm)= "1"

vol - and vol + di nagana sa service mode? sa pad-adjust ng data. tingnan mo nga exact chassis sa board ano ba iyan at ng di tayo naghuhulaan, biyernes pa naman ngayon.
post mo nga mga ic's ginamit. nahihirapan ng mga masters sa iyo. and kung pede pa-picture nga ng naka-service mode ng makita ng husto!

Kasi na try ko din i jump jungle pin#6 to pin #2 at 4 la42032 w/out remove lv ic pero no luck po,naku sensya na pati po kayong lahat ay nabulabog ko pa,e paano ba naman malayo ako sa electronic store sa davao city pa kasi ang mabibilhan ng parts dito which is 3.5hrs byahe from here so 1 day talaga gugulin mo sa pagbili ng part e kung 1 ic lang bibilhin mo naku wla lugi tayo,kaya ito pinipilit ko mapa sounds kahit konti lang temporarily.
