Yes. We accept Visa or Master only.
Sorry, no. But we will discount if the iPhone been repaired other things in our shop before.
First of all, iPhones are not water-proof.
They are just water resistance.
When we do any repair or upgrade on your devices, we will replace the “water-resistance seals” if it’s damaged.
But you must know that the iPhone can still get water damaged even it’s not opened before. Let say a new iPhone water-resistance is only good for the first few months.
After a few months, the iPhone suffered the hot weather and cold. The rubber seals became weak and loose.
We repaired countless iPhone X, XS, or 11pro that were water damaged. Trust me on this.
We will be responsible for it.
but so far never happened due to our very well trained skills and high-end tools for the job.
Because if the board is never messed by other people before, it shouldn’t have any surprise.
Speaking of which, a long time ago there was a case not related to Audio IC repair, the device was repaired at another shop before our hand. Suddenly the device became dead before we even begin to repair it. But the owner didn’t see it. Then we found out the motherboard is in very bad condition, the last shop they overheated the motherboard and caused a lot of potential problems. They were very lucky to return it to the owner before it becomes dead.
Since it died in our place, we will repair it without additional cost.
But the board condition is that bad, the best option was to fix it with the ultimate method – Transplant to a new board.
Transplant means we move the CPU and memory into another motherboard. Everything working nicely.
But let say if there is really an accident that causes the iPhone to become fully dead in the process, we’ll just replace the motherboard without need you to pay more.
The risk is 0.1%.
Why does it happen?
The Audio IC failed is because the solder joints below the ic-chip are broken.
Due to the iPhone 7 design problem, the motherboard of that spot is the weakest. Once it suffered a hard fall to the floor, the audio ic is the first thing to get damaged.
Not entirely your fault. It’s their design problem that they didn’t expect it.
Don’t worry, it can be fixed permanently.
Do not send your device to a regular repair shop to fix this issue. The Audio IC on iPhone 7 and 7 Plus is located behind the Baseband and CPU, and an inexperienced technician can easily damage other components, causing the device to fail. If you send me a dead device, it will cost you more money and take longer to fix.
The second reason is that regular repair shops don’t apply a permanent solution, and the problem can reoccur again, even after changing the IC.
It is important to avoid poorly trained technicians who may cause more damage and fail to repair the device. There may be more damage inside the device than you think, and a simple problem can become a complicated one. In such a condition, the cost of repair will be higher too.
How to repair iPhone 7 Audio IC?
To fix this issue, the logic board needs to be removed from the housing.
The Audio IC is located just behind the logic board. A hot air soldering station is used to remove the Audio IC, but the technician needs to be very well trained to avoid overheating and damaging other components.
After removing the Audio IC, we will desolder all the remaining balls on the logic board. However, most of the time, we can see that there is a broken pad.
The real problem originates from the pad pointed out by the arrow. This is the pad that easily breaks and causes the Audio IC to malfunction. The Audio IC itself is not broken.
99% of the iPhone 7/7 Plus Audio IC problems are caused by this connection.
Sometimes, the pad may appear fine after we remove the IC, misleading technicians to believe that it’s just an Audio IC problem. They may replace the IC, but this fix only lasts for a short time, and the problem reoccurs later.
The internal breakage of the pad makes it barely connected.
The Audio IC on the iPhone 7/7 Plus is labeled as U3101 in Apple Schematic. This C13 pad is connected to the R1103 resistor and then directly into the CPU, making it a crucial component.
The motherboard’s flawed design makes this spot easily breakable.
Therefore, the pad needs to be rebuilt, regardless of how it looks.
We need to create a strong “wire jumper” from R1103 to this C13 pad to permanently solve the problem.
The final step is to reinstall the IC back onto the logic board. If the Audio IC has been previously fixed, there will be green glue beside it.
After the repair is completed, a final test is performed to ensure that everything is working properly.
Simply go to the voice memo app and try to record your voice. If it begins and is able to receive your voice, then it means that the Audio IC is working properly.
