A picture is worth a thousand words, I really dont know what youre talking about but here are some suggestions.
If youre talking about the inductor coils, theyre VLS252012 series SMD Inductors.
LED Power in = 5.6UH 1.15A 474MOHM (This is the one you want)
LCD BST Switch = 2.2UH 1.8A 155MOHM (Replace if broken)

If you are talking about the apple chip, thats a dialog semiconductor PMU, if coil voltage is not OK then you want to get a new one.
