Your mobile phone’s circuit board, or commonly known as motherboard is a very complex component. Without it, your phone wouldn’t be able to function. It is, in fact, the heart of your entire device like a CPU is of a computer.

The circuit board holds together multiple crucial parts of your mobile. Let’s say your heart fails. What happens then? Your body stops moving and you are considered as dead. Similarly, if your motherboard gets damaged somehow, your device will stop working. Thus it’s important to identify whether your phone is malfunctioning due to a defective motherboard.

However, it’s not an easy job to repair your phone circuit board. Luckily, our experts at Hitec Mobile can easily figure out what’s causing your phone to malfunction and repair it accordingly in no time.

1. Motherboard repair Requires A Special Skill-Set

If your tablet or smartphone is malfunctioning, it may require a range of repairs from replacing its screen to a full-fledged repair of its motherboard. If you’re not a technician, then it will be difficult for you to define what’s going on with your phone. You need a lot of experience and some special skills to be able to repair a iPhone motherboard.

Keep in mind that repairing your mobile from an inexperienced or unqualified technician can cause further damage to your device.

However, as long as we’re here, you have nothing to worry about. The HiTec mobile technicians are experts in all the above-mentioned fields. They can ace all type of mobile phone repairs ranging from simple to the most complex. Repairing an IC on a motherboard is an example of one such daunting tasks. Furthermore, a motherboard’s fuses and ICs can malfunction due to flaws in design or total component failure. With years of expertise, it’s no longer difficult to detect and fix such issues.

2. Dedicated Tools and Workmanship

To repair a motherboard, one must be able to master hot air gun ic removal techniques, soldering, handling of precision tools to be able to tackle complicated capacitors and diodes on a circuit board because circuit board is as complex as it can get; therefore, only a well-trained technician can and should handle them.

Soldering is by no means an easy job as it makes use of high heat. If one doesn’t know how to do it properly, odds are the heat could melt down and cause severe damages in other working components.

As you know, it is too difficult to learn by yourself the art of Logic board repair technique without formal training. That’s why even watching YouTube on repair DIY for the whole month would not be enough to repair faulty motherboard on your own theoretically speaking.

What are the symptoms of a faulty motherboard?

Similar to how a disease can cause various symptoms to arise in a human body, the indications are endless for different types of motherboard issues. It is mostly seen that replacing one of the parts, such as the charging port, Wi-Fi antenna, or the camera is sufficient. Let’s take a quick look at the possible symptoms of a faulty circuit board.

Below are the five principal causes of phone breakdown:

  • Continuous usage for a prolonged period
  • Water damage
  • Serious impact on the body
  • Manufacturing flaw
  • Attempt to root android phones

1. Prolonged use.

Motherboards don’t act friendly against heat. Your phone usually heats up when you use it for a long time. This heat tends to wear away the copper and aluminum materials that hold the parts together, and once they lose contact with the motherboard, problems start to show up.

Today's smartphones can protect themselves from overcharging with a safety protocol. This means that your battery will automatically stop charging once it's full. However, overheating can still occur if the battery is faulty. The chemical reaction inside will cause the cell to swell and detach LCD from the housing. To avoid further damage, do not attempt to open the iPhone. Instead, take it to an Apple store or independent repair shop to have the battery replaced by an expert.

Furthermore, if you’re a hardcore gamer or use your phone a lot even when it’s charging, you may start noticing the overheating issue gradually. This happens because while the battery is charging and allowing you to use it at the same time, the process of discharging and recharging becomes stressful for your motherboard.

If your phone heats up even on idle mode, it’s time you checked whether or not your device is due for motherboard repair.

2. Water damage

A minor water spill or splash is unlikely to damage any phone. However, the majority of smartphones will not survive a 1-meter dive down the water or even 10-15 minutes in the rain.

Even though most flagship smartphones today are waterproof (or so they claim), if you look closely to the details, you’ll notice that they’re actually “water-resistant.” In fact, many manufacturers don’t even include water corrosion as part of the company’s warranty policy.

Newer phones like iPhone 11 and 11 Pro Max are known to be IP68 water-resistant. You can click here to learn more about their disclaimer warranty policy.

It’s known to us that water will damage all sorts of electronic devices—no questions asked. When the motherboard comes into contact with water, a spike in the current causes short-circuit. This causes your device to shut down. Contact to water can also cause a chemical reaction that forms into fungus and algae on your motherboard. The longer your phone is running with water damage, the more short-circuited its parts and chemical produce will be, making it very difficult to save your phone on the long run.

Therefore, if your device comes into contact with water, make sure to power off immediately and look for the quickest way to dry up your phone. After that, you can go to a repairer to perform a chemical wash on the motherboard to hopefully revive affected parts to avoid serious damage on the board IC chip.

3. Serious physical impact

Have you ever dropped a phone? If so, what was the first thing that came to your mind? Yes! A cracked screen. Most consumers ignore the fact that any type of serious impact can cause possible internal damage to their phone.

Here’s a more obvious example, imagine your phone was run over by your neighbor’s car. Apart from the broken back glass and the cracked screen, you might notice your device to be even flatter than it was before the accident, or be gravely bent out of shape. And we can guess that a deformed smartphone means a deformed motherboard—and this will require repairing.

With that being said, modern flagship smartphones come with bezels that are surprisingly durable and can endure these impacts, and it’s rare to see such instances these days.

4. Manufacturing defect

Yes. You heard it here first. Unfortunately, this is a very common issue. Sometimes, there’s a defect with the motherboard’s engineering design which causes some parts to break down quicker than the rest—and this is where we come to your rescue.

These manufacturing defects are the reasons why mobile repairers like us can earn a living. And, we do so by fixing their mistakes, so it’s a win-win; you get your device fixed, and we gain a loyal customer. Remember, if you service your phone with a qualified technician, you reduce the chances of damaging the device entirely.

Below are some commonly known manufacturing defects that occurs to Android and iPhone devices:

  • Oneplus Phone: eMMC (which keeps the data storage in phones) error causing the device to auto-reboot or get stuck in a boot loop. This is a known manufacturing defect of Oneplus where the eMMC component on the motherboard breaks down. The defect is so common that most used smartphone dealers are no longer accepting second-hand Oneplus devices.
  • iPhone 6 to 6S Plus: Battery begins to drain quickly right after a software update. This happens due to the software not being compatible with the battery version.
  • iPhone 6 Plus: The poor design of the iPhone 6 Plus causes the device (motherboard) to bend 7.2 times more likely compared to the iPhone 5S after an impact.
  • iPhone 7 Plus: Touch issues. This problem is very common and is caused by the Touch IC malfunctioning on the motherboard.
  • iPhone 8: Does not power on. This is another common issue of the iPhone 8 device. You can click here to learn more about it.
  • iPhone XS Max: Water Damage problem. If the phone comes into contact with water, it causes a lot of issues, despite having IP68 Rating.

5. Rooting Android phone

The term “rooting” is vastly popular in the world of Android. Like any phones, Android also runs on an operating system (OS) designed specifically for casual day-to-day use. Usually, the OS comes with a few restrictions and limitations in place in order to protect the stability of the phone, as well as its components.

Rooting is a practice of removing such limitations and restrictions. This process lets pro users actually to modify the OS itself.

Rooting feels great when everything is working fine. When things get a bit rough, however, it’s bad news for the device and its user. A rooted device basically allows you to overclock the processor. While “technically” it does make the phone run faster than it has any right to, it’s still not recommended.

You simply cannot buy a CPU cooler for your smartphone like you would for your computer processor. Hence overclocking is not even an option here. Making your device run faster than it was originally designed to will generate additional heat, which will damage the parts on the motherboard eventually.

When your smartphone breaks down, it’s crucial to repair your motherboard as soon as possible if you want to save your device.
