The motherboard is the main microcircuit of each computer device, whether it is a PC, laptop or mobile gadget. It houses the key chipsets. Therefore, replacing the motherboard of a Sony smartphone is a very responsible procedure, requiring experience, attention and thoroughness from the performer. Careful attitude to the smart phone, other external and internal factors provoke breakdowns. Consider:
- Symptoms of a malfunction;
- Tools and materials;
- Repair process;
- Guarantees.
Symptoms
The reasons for the breakdown of the motherboard of the Sony phone are related to the mechanical impact on the smartphone, which affects the operation of the components located on it.
As a result of falling or hitting, the video chip, processor, speaker or microphone, RAM and power and volume buttons can be damaged - the range of hard is quite wide. Filling the smartphone with liquid leads to oxidation of the contacts of the microcircuits. As a result, corrosion is detrimental to technology.
This disrupts the electrical exchange between the elements and leads to a “point of no return” for the gadget. To prevent this from happening, it is recommended to treat the device with attention, not to allow it to fall into water and not to pour liquid substances on it. In addition to the above, power surges in the electrical network lead to damage to the motherboard. An out-of-service motherboard needs to be replaced.
Tools and materials
In the process of replacing the motherboard of a smartphone, Sony Service Center engineers use only certified equipment and tools. Infrared and hot air, contact soldering stations, binocular microscopes and oscilloscopes are a mandatory minimum for professional service. Of the tools, delicate plastic spatulas, tweezers, sets of screwdrivers and brushes, cleaning products to remove grease stains and dust are used.
Work process
To find out the exact cause and scheme for restoring the device, Sony conducts free diagnostics. Next, a complete disassembly is required. This is necessary to replace the affected element of the smart phone. An experienced master makes a replacement in 15-20 minutes.
After removing the outer parts of the case, the engineer snaps off the coaxial cable and connecting the screen and battery cables with a plastic spatula, disconnects these parts. For high-quality disassembly of the device, skill and training are needed, since this is a filigree work that requires concentration - one wrong move can damage the internal elements of the gadget.
Using tweezers, the Service Center master carefully removes the affected board. Now it remains to install a new one and assemble the Sony smartphone back, not forgetting to put the removed parts back. Only original spare parts obtained from the manufacturer Sony are taken for replacement. The repaired device must be tested.
Guarantees
The service center guarantees to replace the motherboard of a Sony smartphone - it is up to three years. SC operators discuss in advance with the client the scope of repair work, delivery time and where to deliver the mobile. And the courier service brings the restored device for free.
Removing the motherboard
The motherboard is the heart of any smartphone. It integrates all the elements of the phone and ensures their common work. Therefore, if the motherboard has been damaged, then further operation of the phone is often impossible. At best, individual modules on the board can be damaged, and the resulting problems in the system are not critical.
The phone's motherboard is always located in the case and can only be accessed by disassembling the case. To do this, you need to remove the back cover, and for non-separable models like Sony Xperia Z, Z1, Z3 and others, it is problematic to do it yourself. For them, the manufacturer provides a sealed assembly to protect against water. After detaching the back cover, you must remove the battery and disconnect all contacts. It is no coincidence that this sounds complicated.
Replacing a motherboard with a Sony Xperia is a very time-consuming and difficult job that requires not only special tools, but also skill. However, on any smartphone, the procedure for repairing the board is painstaking, as on Sony, because, unlike the external design and differences in the location of the control buttons, the internal structure of mobile phones and elements is the same.
Signs that indicate the need to repair the motherboard of Sony smartphones
According to MOBILA MASTER experience, this list looks like this:
1. The phone does not turn on, although it is fully charged;
2. The phone is constantly rebooting;
3. There is no charging from the network or when connected to a PC, or the device is quickly discharged. Here, before repairing the board itself, it is necessary to exclude malfunctions with the battery;
4. Control buttons do not work: power on (lock), camera, volume; various connectors and slots, cameras or speakers are faulty. Again, diagnostics will help establish a more accurate cause;
5. In general, the phone does not work properly, and the possibility of using it has decreased.
Motherboard recovery
The reasons for repairing the Sony Xperia motherboard are pretty standard:
Strong mechanical impact - impact of the mobile when falling or otherwise;
Water ingress or moisture oxidation of the board elements after insufficiently thorough drying, and this is also true for waterproof models in case of leakage or banal inaccuracy when closing the plugs;
The use in the previous repair of not original spare parts, but Chinese fakes, often not suitable for Sony;
Overheating of the device;
Damage to the connectors, which caused damage to the board;
Attempting to repair the smartphone yourself, which led to additional damage.
Since this element is the most expensive in a smartphone, and its price is often comparable to the cost of a new phone, most service centers in Moscow, after determining the cause of the malfunction, can offer two options:
Completely replace the motherboard with the original one for Sony Xperia;
Repair the motherboard and replace only individual modules responsible for a particular process.
Although, but this type of repair is not always advisable, because, with sufficient professionalism, repairing the board will extend the life of your Sony and save money.
