Hi, I as doing a battery replacement on my iPhone X. After installing the battery i connected the LCD and Digitizer to test and found it turns on. I then disconnected the screen again to install a new one. After installing the front microphone etc on the new screen and reattached everything back to the logic board in order to test and found that it would not turn on. Have tried going back to the previous Screen but that doesn’t turn on as well. Have tried disconnecting the battery, reseating the connectors and (volume+/- and power for 40 seconds). But no luck. Any way to check if the device is turning on or if the logic board is faulty?
Plugging phone into my mac, caused it to boot. Post boot the device didn’t charge so replaced the battery again and it works fine.
