My phone is not getting charged and not starting

@vivek92182 you are saying IC is not working but are not telling us which one and how you have checked it. I would at least check/replace the charging board before assuming it is an IC on the main board. Use something like this video to replace the charging board. Replacements are readily available at many online stores and really not to expensive.

While you work on your phone, take lots of pictures. Once you are done with it, take those pictures and create a guide for iFixit. That will help the next person that has a device with the same issues as you do. It's easy and fun to create these guides. https://ifixit.com/Guide/new The iFixit community will appreciate this.
