I am trying to fix my Grampa’s iPhone SE because it has a bad battery and a cracked screen, I tried removing the screen...

I believe the displays are all dead since they all display the same symptoms now (no lcd or backlight) so this narrows it down to a faulty installation on my part. The lesson is to always disconnect the battery before connecting/disconnecting another component to prevent display shortages and other phone anomalies I also discovered that you need to connect the iphone to a lightning cable to get it to boot after working on it so this is what I suggest doing If reassembling a phone: plug in all the components THEN the battery after connecting the battery you can connect the phone to a power cord if it doesn’t boot If disassembling the phone: remove it from any charging cables/wireless coils disconnect the battery FIRST if possible (it might not be because some phone companies make their phones very difficult to fix) My final words are to always keep your screws organized and to follow the guides here down to the word they’re only effective if you follow them completely
