iPhone 6S Replacement Screen and Battery Not Working
I replaced the battery and screen on an iPhone 6S for a friend. She ordered the parts off of eBay. She said that even though the screen was cracked, the LCD still worked. I first disconnected the battery and swapped it out. When I went to turn it back on, it made the noise like it recognized the charger, but the screen was totally black.
When I swapped to the new screen, it had the same problem. The battery says that it has the same voltage as the OEM battery, but it was supposed to be 2200 mAh, as opposed to the standard 1715. I checked the connectors and they don’t appear to be damaged. Also, it is still able to receive texts. Every once in a while the phone screen will flash when it is turned on. I have changed a lot of screens in the past and have never seen this issue. Does anyone know what it may be?
