iPhone 4S display black and constant vibrating (sounds) when charging?
I was repairing an iPhone 4S for someone and all went well. I reassembled it and turned it on, but the screen was black. At first I thought the battery was flat, but the phone was on and working (the CPU warmed up etc. etc.) I plugged it into my computer and it makes the sound that any iOS7.x.x makes when you start charging it. Thing is it makes this sound every 10 seconds or so as if i'm plugging and unplugging it. The screen is still black all through this. I assumed that the LCD was dead. (at this point I'd tried cleaning the connections, reseating the connections, blowing the phone out with an air canister, restarting the phone, resetting the phone. (I haven't restored it as it's not mine and refuse to do it without permission for obvious reasons). None of this has worked. I gave up and fixed a few more things by this point the battery had ran dead and I plugged in a new 4S screen that I had lying around. I held down the lock button and it worked, the phone showed the "needed charging" icon so I plugged it in and let it charge for 30 minutes. I came back and all was working well, so I unplugged that screen and plugged in the installed one, and truth be told the screen was black again. I plugged in the other screen and it was black too. I tried 2 more (cracked but working) screens and they were black also. I replaced the battery and it was still black. If it was a faulty LCD why would it not work with the other screens? If it was a damaged motherboard why would it work, not work, work, then not work again? I'm baffled. It's also recognised in iTunes, but has a password (which I have, but I don't know exactly what I'm pressing so unlocking it is a pain)! Any help would be greatly appreciated as this is the first time it's happened and i've fixed probably 40 iPhone 4S's. Thanks in advance! :)

I'm having an issue where my iphone 4 is stuck on a black screen with continuous vibrating and since my lock button is broken there's no way I can do the reset. I can't take it to the ATT store for another few hours because I dont have a car so I'm stuck here at home with a quickly overheating nonstop vibrating phone. I don't know what to do to make it stop. Considering throwing it across the room. :///

I lost my iPhone 5c and it was returned the next day to me but would not turn on. I put it in the charger, it keeps making the charging connection sound every 5 seconds but the screen is still black. I have tried everything to make it work but nothing is happening. Any help would be great. Maybe the person who had it while it was missing took something out or damaged it? I don't know...

My iPad is on, but the screen is black, the home/power thing doesn't work and the turn off voice over doesn't work. I can talk to Siri and go into apps, but the screen is still black, this is my school iPad were talking about! Can someone please help me?

Take it to a mobile phone repair shop / someone experienced to get it fixed. Sounds like a LCD cable connection issue.
