iPhone 6 Power Troubleshooting Help
Hi, I recently worked on an iPhone 6 of mine (solder work with the sim card slot), put it together, powered it on, and plugged in the lightning cable. Moments later, I heard a faint crackle and the phone is no longer working (will not power on). It seems I may have left some of the flux behind and I’m not sure what’s damaged. Before that, I installed a new lightning cable assembly and battery. I’ve since cleaned it out with IPA to the best of my ability without removing the heat shield near the display connectors.
The battery terminals on the board (the larger ones on the outside) are not getting any voltage with the USB plugged in. Somewhere on the ribbon (I don’t know the pin #s) from the lightning cable to the motherboard, there’s 5 volts. The battery is showing about 2 volts so I suppose it needs a charge.
So it seems I’ve shorted something… What components should I troubleshoot first? Do I replace the lightning connector again? Any way I can manually charge the battery to test the rest of the phone? I have a hot air station but I haven’t done any IC replacement yet.
I watched this YouTube video but he works very quickly and I need an idea of maybe the first 2 places to check based on what I’ve shared here. https://www.youtube.com/watch?v=Konvdpt4...
Thanks in advance.
