In DCT4 the are more possibility component that may cause "Short" fault. But the most simple way is use Power supply and seek the component that overheated....

only tips for shorting:
dont ever remove PF(PA) before remove L(induktor) before PF, its + to PF. if remove this L and short gone, damage 100% PF.
most Nokia have this L. if remove and still short, its no PF damage.
try find C(capasitor) filter, open diagram, this conect both + and ground (ex: in charging circuit after L).
maybe more five C with this position, but diferent place, try remove one by one and check.
final, try connect with batrey and touch all component, whereis hot, this area is short.

maybe help
