My phone, Galaxy S7 Edge, does not turn on and does not accept chargin

I opened the device, checked the dead battery, it does not give a value, then I installed the charger and checked the battery port, it outputs 2.4v. Now I want to check the outlet of the charging socket that feeds the motherboard, but I did not understand how to check it. I want you to give me videos or pictures of how to check it, and then I want to accurately diagnose the defect Please advise us of all the steps, may God reward you

@loukman if you do not get the 5V on L7022 you know that it is your charging board.

The charger should be outputting 5V. If it is only 2.4V, it is not charging the battery and the battery is dead, which is why the phone does not turn on.

@loukman I do not have a board laying around to get the pictures for you. Best I have are the schematics and component layouts. With that you can most certainly test your board.

If you only get 2.4V on your battery port and you are using a working charger, the issue is most likely on your charging board. Use the Flowchart to measure it out.

My experience with Samsung's would be to replace the charging board. You can use these guides Samsung Galaxy S7 Edge to work on your phone. or you could use something like this video for the specific board. Or use this guide in iFixit fashion :-)

The board is readily available at many places. Just do an online search and choose a vendor that appeals to you.
