iPhone 3G: No display after repair

Sat, 15 Feb 2014 04:38:25 -0700

I've googled everywhere, and scoured this site for an answer to my problem. My problem IS like a lot of the other questions, but the fixes don't work. I can turn the phone on, hear sounds when I plug it into my MacBook, shows up in iTunes, and it vibrates when I flip the silent switch. The only problem is having no display/backlight.

My friend brought me the phone after finding it laying on the ground with a cracked touchscreen. Everything else was perfect on it, display lit up and everything. I replace the touchscreen, reconnected and it worked fine! Here's the kicker. The Home button wouldn't work, so I pulled it apart to fix the button contact but the #3 cable came loose. I have all the flex cables secured with dental wax (random, but it works and isnt too messy). I tried:

A. Holding Home+Power for 10s or until Apple logo shows

B. Removing the logic board for 5-10 min away from the battery.

C. Doing a full restore

Sorry for the long post, just wanted to give as much info as possible. Can anyone help me? He needs the phone back in a few hours, and I'm at my wits end. Also, this is NOT my first repair on an iPhone 3G. I have had MANY successful repairs.

I am having problems with a sim card reading in this phone, the copper feet seem fine and there is no liquid damage, however the sim reader is only intermittently reading the sim. I am wondering if it could be due to the part circled in the picture, and if so what does it do? Thanks!

Wed, 07 Sep 2011 16:11:00 -0700

Can this situation be beneficial for both of us?=)

But Im more concerned about the bezel...,i know that the housing itself fits fine...But the bezels are they the same in 3g/3gs?

Because mine is already attached to the housing!

iPhone 3G: Won't charge, any ideas?

Tue, 12 Jul 2011 12:56:31 -0700

Hi,

iPhone 3G stopped charging, but speaker and mic works ok. Swapped the dock connector / speaker assembly for an old one which had a duff speaker. Phone charged fine. Tried 2 x brand new dock connectors but just getting sound but no charging.

Why would it work with one dock connector but not the other?

All screws are in place bar the two in the bottom of the phone, all connectors are in place securely

It's driving me mental now!!!

The battery died and when I tried to restart it, all it does is showing me the apple sign, but it does not go further. I can't start/restart it, and I can not restore it because iTunes wont recognize it until it starts.

iPhone 3G: Won’t turn on, replaced batter

Would love for there to be a way to have fixed because many of my moms memories are on it. Also, mom said that she had try to plug it into a computer to get photos but nothing came from it. Would appreciate any help.

I’m was trying to replace my iPhone 3G with a new rear case and when I was taking the camera holder cap out of the old housing, the little metal ring fell out from the frame and lost it. I looked everywhere online for a replacement but couldn’t find anything about it.

iPhone 3G: How do I recover my info on my iPhone?

Fri, 15 Mar 2024 05:36:31 -0700

Hello,

So recently, the battery in my iPhone 3g decided that it would not hold a charge anymore, and when I plugged it in to power, the iOS 6 setup menu appears. I was devastated, because I did not back up my iPhone, and I probably lost a whole bunch of old photos. Is there any way that I can restore my iPhone so that I can get the photos, if at all possible?

iPhone 3G: My iPhone won't boot up.

Sun, 13 Feb 2022 12:27:56 -0700

I got this iPhone from a family that doesn’t use it anymore. It still had their iCloud and data on it, so I reset it. After doing that it went to the Apple Logo and hasn’t changed since. I left it overnight and eventually it died. When I plugged it back in, it did the same thing again. When I try force restarting it, it turns off, then goes back to the Apple Logo.

What should I do?

iPhone 3G: I broke the pcb near the do not remove sticker

Tue, 09 Feb 2021 07:50:02 -0700

Hi there! So I’m sure you can tell I’m a noob to repairing stuff after this. So, I was taking apart my iPhone 3G, and got almost through taking the screws out. Once I took all of the visible ones out, I proceeded to pull out the PCB. I didn’t remove the sticker that says do not remove :(, so I cracked the PCB right near the screw. What does this do? I’m kinda worried, but I don’t need this phone for cellular, I need it for CoD WaW Zombies haha.

iPhone 3G: iPhone 3G keeps turning on by itself

Tue, 17 Nov 2020 06:16:28 -0700

So I`ve just bought a 3G to add to my ever growing iPhone collection. I`ve set the phone up and all is working normally however, when I turn the phone off it automatically boots straight back up again. My theory is possibly the battery, but I`ve noticed the screen has been replaced with a third party one, so not sure if that could be causing it. Any help would be much appreciated.

Luke
