Check all the components that are surrounding your Power IC, if any of them is found to be faulty then replace it, as if any of the component is damaged then your Power IC won’t turn ON.
If all the above methods fail to resolve your power problems then all you have to do is to gently heat your Power IC with the help of a heat blower, if it fails to perform then re-ball and re-fix the IC.
If heating or re-balling of Power IC doesn’t do any good to you then replace your Power IC, as there is nothing you can do besides all that.
