Hi, I replaced the power button flex cable on an iPhone 5 because the button was not working anymore. I put the whole thing back together, but it won’t turn on anymore. Nothing happens when I hold the power button. When I put the phone on the charger, it starts vibrating every few seconds but doesn’t turn on. When I connect it to my computer, the computer does recognize the phone, but the phone keeps vibrating and won’t turn on. I had a spare battery, so I tried replacing that, with the same result. Does anyone have any idea what’s up?
It’s fixed! I had to replace the screen. Most likely, the flex cables were damaged.
A phone that is vibrating with no display is telling you, “My display isn’t working, my display isn’t working!” This can sometimes be a software problem—if the phone has never been opened, for example. A hard reset can solve this problem. Hold the power and home button for 10 seconds. If it’s not a software problem, then it could be damage to the flexes of the screen itself—the LCD flex. Replacing the screen can solve the problem. If not that, then it could be damage to the LCD or digitizer connector on the board. Anyone who has tried three or four screens and then it magically works again—they were probably able to finally clear debris out of their connector or straighten a bent pin. If the connector is damaged, it can be replaced as a board-level repair If not that, then it can be a blown backlight filter (like a fuse). This can easily happen when using certain replacement screens that have an exposed backlight flex solder joint. Pressing the screen into the frame will cause the exposed joints to short the LCD line to ground and burn the filter. This can also be fixed as a board-level repair. If not that—you could have drop damage or latent water damage that is causing a problem in the backlight line elsewhere.
My phone just randomly turned black so I figured it was over heated, so i just let it chill for a little and plugged it in. It vibrated when I plugged it in, but still didn’t turn on. I looked on here and realized that people were saying they had to replace the screen. I found a very helpful video on youtube that first says to press the home and lock button down at the same time which is what I had already tried. If that doesn’t work then hold down the lock button for 3 seconds, then hold the home button down with it. That worked for me. No need to replace my screen!!!
I had this problem with an iPhone 6 that was completely dead and plugged into a charger during a repair. I disconnected the battery for a full 2 minutes, reconnected and assembled the device. Turns on and works flawlessly. Good luck guys!

Give it to the “geniuses” at Apple. They will “fix it.”
