hello everyone, looking for some help. i dropped my iphone 6, and when i picked it up it was still on, conected to charger but then wouldnt charge, battery eventually died. wouldnt power on after that, changed the charging port to a new one, still no power. no visible signs of damage to screen or battery, any advice on what else i can do, im not a big expert but can do most of the basic stuff. thank you
Chances are your phones logic board sustained some damage. You could try a new battery if you have access to one but my suspicion is that this is not a module-based issue. I would start by testing a bare-bones setup. Start by disconnecting the battery first (always!). Then disconnect the digitizer, LCD, front camera, rear camera and home button extension flex (see this guide). Now re-connect the battery; you should only have the battery and Lightning Dock flex connected. Connect a known-good, preferably Apple-original Lightning cable to an iTunes enabled computer. If you have access to a multimeter, you could measure the battery first. If it reads ~3.8V - 4.2V, then it is good. Does iTunes recognize your phone? If so, then you should re-connect one flex at a time until the phone stops working. I would start with the Home button flex first, then add the rear camera, LCD & Digitizer then from camera flex. If the bare-bones setup does not get recognized by iTunes, then you most likely have a logic board issue. You could send it (or find a local) to a repair shop that specializes in micro-soldering repair. Sometimes the fix can be straightforward (i.e. a blown filter) and relatively economical.
