I work at a tech company and a customer brought in his Moto Z, we quickly determined the battery was the issue as it ran out within minutes, so we replaced it. The issue we encountered from here is we noticed the screen had cracked, so we ordered a replacement for that. When the replacement came in, we quickly repaired it, yet the screen stayed black. We could feel the phone vibrating, so we knew this screen was a defective part. We returned this screen and got a new, much nicer looking one than the one we had been given before (neither of these are from here, just providing details). We put this screen on and plugged everything in correctly, but now the phone does not turn on whatsoever. We feel no vibrations, and once again no image is shown on the screen. Could this be damage to the battery from heating the phone to melt the adhesive when reapplying the screen, or is there any other possible issues? Thank you to anyone who is willing to share thoughts, recommendations, etc.
When you connect the new screen you MUST disconnected the battery or it will fry the screen so that’s what happend.
Stupid question. Did you charge the battery? It’s possible that when you put the new screen on and found out that it was bad, you just took the part off and forgot to turn off the phone. That would explain why the phone didn’t turn on. If that’s not the case then I’m not sure what happened. Heating the battery should not cause problems however did you disconnect the battery first before heating it up? The only other thing I can think of is that at some point during the repair something on the logic board got shorted out causing the device to not power on.
