I just replaced the battery in an iPhone SE (first gen) with an ifixit battery replacement kit. I’ve done this twice before on an iPhone 6 without issue. After replacing the battery, the device won’t power on at all. Shining a light on the screen does not show a faint image. There’s just no power at all, it seems. I tried open it up and just connecting the original battery (it still had some charge) to see if it would power on, and no dice. I followed the ifixit procedure exactly, making sure to disconnect the battery before disconnecting the screen. I disconnected everything again and re-seated all the screen ribbon cables just to make sure. I had no problem seating them, I used a magnifier to look closely and ensure I hadn’t damaged any pins. I was extremely careful at keeping track of the screws so I didn’t accidentally put a longer screw in the wrong socket and thus damage the logic board. The only thing that happen was when I first opened the case, it popped rather quickly and pulled the home button ribbon cable off. I was extremely lucky, as it had no shield over the connector, so it simply popped off without any damage. However, even if that got damaged, all I would expect is a non-functioning home button. It should still at least power on, I would hope. I’m not sure what I can do to troubleshoot this, and would appreciated any suggestions.
That’s a very thorough explanation of your steps and you did everything “right” from a repair perspective. Here are a few suggestions and observations: If the phone had no shield holding the screen connectors, that means it was repaired before (by whom?). There may be some history there, like overtightened screws. Sometimes issues stay latent for a long time and only resurface after a strong impact or subsequent repair.While the typical screen repair related issue is a blown backlight filter, sometimes it’s the LCD driver that gets blown. However, you do say that the battery was disconnected first. Was it also the last thing connected after the screen replacement?Did you check for any pry damage around the battery connector? Accidentally prying FL2400 (see image below) can cause the symptoms you are seeing .It could also be that the screen was damaged when you lifted it off. Considering it was previously repaired, it may have been a lower quality screen.You can use a USB Ammeter to determine if the phone is really drawing current when it should be charging.Try connecting the battery but without the screen. Then connect it to an iTunes enabled computer. Does it get recognized? If yes, then the phone is alive and you have some display/driver related issue. If it isn’t, then you likely have a logic board issue.
Hi Peter, I am no expert but my suggestion would be to charge the phone and try a hard rest on the phone by holding the power button and home screen button. It may be that the phone needs a bit more charge to get up and going again. The only thing I would be concerned about is if there was a short or something broken inside, that could cause a power surge in the wrong place and the device could stop working altogether. Best of luck to you and I hope this helped somewhat!
