hi all as we all know that i had a d500 with wht screen fault.
i hav changed the flec, flex connectors, charging jack.............but same results. still wht screen fone is on nd all sounds hearable.
now after tracing it for long time nd i found two big faults.
first is that U600(a3212elh) that is a MICROPOWER, ULTRA-SENSITIVE
HALL-EFFECT SWITCH
it was fully input to gnd short. now i replaced it with a same a3210elh from a diff. samsung fone.

second fault is in the pic that the prints on the board highlighed with red points r short even if the esd filter is removed. that fault is no removable by me. i tried to fix it but unable to do so. now i need ur hlp brothers, plz suggest me how to remove the faults.............
