Firstly, we will test your board with our known good parts. This helps us to know if we have a part problem of if we have a board problem. If the board is okay, and we only have a part problem, then we will tell you and replace that part if you agree.
If the phone has a board problem, such as a short, then it starts to become more complex. We will have to start measuring power rails, seeing where the majority of the water damage is, and clearing any shorts we may find. We must clear all shorts before replacing any of the broken parts otherwise the phone will remain dead.
