iPhone Motherboard Repair

Please fill out the intake form for questions and before sending any phones in for repair

iPhone motherboards are some of the most technologically advanced pieces of equipment that modern consumers have access to. They pack a maze of intersecting voltage lines, controlling a multitude of different functions, into a tiny area inside your iPhone. Everything that your iPhone can do is controlled by the motherboard; it acts as the brain.  Once the iPhone X was released it became clear that iPhone X Motherboard Repair and higher would become quite common. It is a stacked board that can be prone to voltage line disconnects. UNABLE TO ACTIVATE and NO SOUND DURING CALLS are both examples of iPhone XS Max Motherboard voltage line disconnects. 

There are a few ways that iPhone motherboards will typically fail:


Over time, flexion of the iPhone can break the voltage line traces causing disconnects. When this happens, a jumper wire is used to manually reconnect the broken line. The problem is gradual and usually goes unnoticed. 

High Impact

A cracked screen is not the only possible outcome from a dropped phone. If your phone suffers a severe drop or is crushed it is likely that the motherboard will also be damaged. Capacitors become shorted, coils become loose, and chips become smashed. 

Spontaneous Failure / Voltage Spike

Sometimes it is unclear why the logic board failed. Often, a capacitor will be found shorted on power lines for seemingly no reason.

Water Damage

Water will wreak havoc to a motherboard. In most cases, a motherboard that has been damaged by water will show problems for the rest of its lifetime, even if repaired. For this reason the best solution is to perform IPHONE DATA RECOVERY if you do not have a backup and purchase a new phone.

Causes These Problems:

No Power / Dead iPhone - Most iPhone logic boards problems will manifest in the most simple way, a phone that does not work.

iPhone Boot Loop - This refers to when an iPhone will not fully turn on, instead only showing the apple logo for some time and then repeating. iPhone X, iPhone XS (Max), and iPhone 11 (Max Pro), are especially vulnerable to boot looping because of their stacked motherboard design.

Audio IC / No Sound / iPhone Sound Not Working - The iPhone 7 Audio IC was a wide spread problem causing many people to suffer from audio issues. It affected a great number of iPhone 7, however, it can also be seen in other models.

Touchscreen Not Working / No Touch - Your phone will turn on but the touch function will not register anything. This is most common in the iPhone X and iPhone XS. It was also seen widely in the iPhone 6 Plus as a signature problem.

No Service / No Signal - All iPhone Logic Board models have suffered from no service problems manifesting from a very complicated baseband circuit. It is a huge and complicated circuit with many components that can fail in a variety of ways.

The motherboard controls every function of the phone. Because of this, any problem that occurs has the potential to stem from the motherboard. Please fill out the Intake Form for inquiries.
