Remove V2000 And Cross Track The 4 Balls.before That Change The Fuse Coz U Say Its Shorting

i do that ,but it's short
i trace charge track and remove all components that can make problem,except TAHOV
and it seem that TAHOV is responsible for this
i'll change it and post result

i removed TAHOV ,and board is without this ic
but it's still shorted,i confused
as u see in charge ways in my attached picture,there is nothing else except F2000 & L2000,but charger connector (X2000) ,is shorted still.
