Here are just a few examples of repair work recently completed. An iPhone 3G came to us with a Home button that was not working. We removed the screen of this iPhone and tested the Home button circuit which worked fine. With a 3G iPhone, the Home button circuit has two contacts underneath the screen that must connect to a second cable attached to the iPhone's logic board. If the iPhone is dropped or becomes twisted, the damage might create a space between the iPhone's home button cable and the cable attached to the logic board. In this case the culprit was corrosion. The previous owner of this 3G iPhone lived near the ocean where the misty salt water apparently built up corrosion to a point where the circuits lost a connection with each other. After cleaning the iPhone with solution, the Home button worked fine.

This next story involves a 3G iPhone with no sound coming out of the earphones. Getting to the headphone jack in a 3G iPhone requires removing the screen and logic board as well as the iPhone's battery. At that point the iPhone's headphone jack can be accessed. The headphone jack is connected to three other buttons including the Power button, the Volume button, and the iPhone's mute button. We replaced the headphone jack circuit and reassembled the iPhone only to find that we had music in both ears, but the music would randomly pause and restart. After realizing we were using the wrong iPhone headset, we used a set that came with the iPhone and everything worked great. The difference is in the iPhone headset plug. The plug on an iPhone 3G headset has four metal contact rings with three black rings. This is to allow the headset microphone to work correctly. Other headsets might only have two black rings with three metal contact rings. Using this kind of headphone plug may result in shorting the electrical connection in the iPhone's headphone jack which makes the iPhone think that someone is trying to call or talk on the iPhone. This forces the iPhone's iPod player to Pause and Play randomly. Make sure you use the correct type of headphone plug with your iPhone if you come across this problem.

Recently one of our customers dropped her 3G iPhone resulting in a cracked screen, missing Power button, and twisted chrome frame (the chrome metal ring that surrounds the iPhone's screen and sits on top of the back cover). In fact, you could slide a quarter inside the iPhone through the twisted frame and back cover. It was in bad shape. Replacing a 3G iPhone's back cover is the most intense repair for an iPhone because it requires complete disassembly of the iPhone as well as removing a handful of small parts glued to the back cover. The chrome mid-frame is also glued to the back cover with epoxy or very strong glue. This iPhone's chrome mid-frame was straightened out to allow a perfect fit with a new back cover. After gluing in the small parts (such as the camera's chrome ring and the headphone jack's chrome ring, we installed the iPhone's headphone jack, battery, logic board and screen. The iPhone now works great and you can no longer see inside it through the twisted frame.
