Why Should I Get My Mainboard Repaired?


There is a wealth of information available (especially on this page wink) about mainboard repair.

But before delving in to the details you'll likely ask yourself "Why? - What are the benefits of repairing my mainboard?".


A quick read here will reveal a few significant factors you may want to think about:



For newer devices its often an easy choice to go ahead as the cost of replacing the device is high.

If your device is older the cost of mainboard repair may seem high versus replacement options.  However if you consider the drawbacks of not repairing, you may think again.


Data Not Backed Up

Data you know that you haven't backed up is probably the most compelling reason to repair your damaged mainboard.

What about the files you don't remember right away or haven't yet synced to your cloud storage?


Data & files like:

  • Contacts
  • Text messages
  • Email
  • Documents
  • Pictures & Videos
  • Applications and settings
  • Personal configurations

will only be accessible or recoverable after repairing
the fault(s) on the mainboard.

data trapped due to faulty mainboardIf you haven't done a backup or your synchronization settings are incorrect or disabled your data files will not be accessible and trapped in your disabled device when your logic board is ailing.


Data that is stored on the Logic Board

Many devices do not have independant storage devices such as a hard drive or solid state drive:

Mobile phones, tablets (such as Apple iPad and Microsoft Surface Pro) always have data stored on the Logic Board.

Many newer MacBooks and Windows laptops no longer use removable storage devices (meaning the data is stored on the logic board).

Any data recovery from these devices require logic board repair before data can be retrieved, extracted or recovered.


Data That Can't Be Synced

Some data is stored only on your device.

You may be surprised just how much data is never backed up to the cloud.

Some examples:

  • Payment settings such as tap to pay
  • Health & fitness statistics
  • Biometric data such as fingerprints, iris scans & facial recognition
  • Passwords and pins numbers
  • Secure applications

In many cases the only chance to free your imprisoned files is to repair the mainboard fault and restore functional access to the device.


Logic Board Repair Prices

The logic board on a computer is sometimes referred to as a mainboard or more frequently called a motherboard.

When replacing a component/part (for example, a screen or a mic, etc.) does not solve the actual problem being experieced, a mainboard repair/replacement is usually the solution.

We will need to complete a diagnostics to determine the extent of the repair required and then provide you with a finalized repair price and time to complete for your approval.

What is a Motherboard (Logic Board)?

Linus from Linus Tech Tips gives a quick explanation of what a motherboard is:

A Device Logic Board may also be referred to as a Mainboard or Motherboard.

iPhone Internal components

Logic board repairs are considered when all other repair options have been exhausted.

The logic board, otherwise known as a mainboard or motherboard, is the primary component of any electronic device. It controls and is connected to all the peripheral components, ie. screen, speakers, charging port, battery, jacks, everything.

When one or more of the connected components fail we most often replace the problematic components -- problem solved. However, if we find the issue persists with replacement parts, this raises a red flag that there may be other underlying issues.

Identifying a solution is of far greater importance than discovering the cause. When a device comes in for repair and it is identified that the issue is with the logic board, we normally look at the symptoms to narrow down the source of the problem and determine the solution.

Internal components, or parts we cannot see from the exterior, cannot normally be identified as being a source of an issue without running some diagnostics. For this reason, we cannot be sure that the logic board is in fact causing issues until the device has had an internal diagnostic inspection.

laptop Internal components

Some common issues with logic board failures can be suspected through its symptoms, but not 100% confirmed without digging deeper.

For example:

an iPhone that doesn't respond to touch may have a defective or damaged screen assembly or the issue could be with the integrated circuit component on the logic board that processes the capacitive touch. The latter can sometimes be identified when a foreign grey bar appears at the top of the display screen.

Logic board micro soldering


We repair all logic board issues in-house using the latest industrial high-performance tools and equipment. Whether your device logic board requires micro soldering, trace restoration, re-balling or component replacement, we are your resource for getting the job done right. To ensure you 3-8 business day turnarounds we service all logic boards at our Mississauga location. Dropping your device off at our Toronto location may take additional 2-3 business days.



Liquid Damaged Logic BoardIf your device has been damaged by exposure to water or any other liquid, you can be sure that the liquid has managed to get to the logic board. In these cases, the resulting corrosion will cause damage to the circuits on the logic board and can even inhibit some from working or the device may not work at all. In some cases, the components on the logic board have become damaged and require further repair as a result.



Flash Memory & Storage Logic Board Repairs

Standard memory sticks with USB Type-A plug are the most common type of portable memory. They come in different sizes and styles and have a very small and convenient package. Internally, the components are all connected to the small logic board, including the Memory chip, USB controller, jack and sometimes an LED indicator light. Read about our USB memory Data recovery if your important data is stuck inside and you need to get it out.

Memory chips, which are normally NAND type storage memory ICs, have a minimum typical life expectancy of 5 to 8 years. It has several I/O points which all connect to the motherboard in order to power the chip and transfer data. Unless the NAND chip is physically damaged there is a possibility to revive the device without replacing the NAND chip entirely. On some less expensive USB sticks, the NAND chip is encased in an epoxy, making it nearly impossible to replace. Memory corruption can also occur, causing the chip to behave strangely. Sometimes the information being read/written can be scrambled or the NAND will not activate as a result of memory corruption.

Inside look at a USB Memory stick showing the logic board and its components

USB controller IC talks to the device its plugged into, telling it what kind of device it is and how to handle it. USB controllers are the intermediary which all USB communication is transferred through. The standard universal serial bus, or USB, connection method is found in nearly all digital devices.

The jack is simply the standardized plug that plugs into your computer, TV, or other devices. We are seeing an increase of different plugs, such as lightning port plug for iPhones and Apple devices, microUSB for OTG devices and the new standard of USB Type-C. The most common and iconic looking plug is still the standard USB Type-A. This is the component that gets the most physically worn down, it is the only part that gets plugged and unplugged from devices. There are small, normally copper, pads which make electrical contact in order to transfer power and data to the device. Wrenching the device while its plugged in will cause the jack to be disconnected from and possibly damage the logic board. Also, the internal pads will eventually wear out with over use. In both these cases the jack would need to be re-attached or replaced with possibly some additional repair to the logic board traces.

LED indicator lights are not really a functional component. The sole purpose is just to let the user visually know that it is on and sometimes it blinks to tell you its reading or writing data. If the LED indicator light burns out it can be replaced, but not crucial. On the other hand, if the LED indicator light is not working and the device its plugged into doesn't recognize it, this could be an indication that something else is happening. No light? No power? Then there is obviously more to it than just the light.

Essentially, since all components are hardwired to the logic board all issues that cannot be resolved by re-formatting the memory is solved by addressing the physical problem on the logic board.

Video Game Console Logic Board Repairs

Possibly some of the more robust and advanced logic boards can be found in modern gaming consoles. There is a ton of high-tech proprietary engineered features packed into the current generation of gaming systems. Alot of power and high-level processing in order to give a modern feel with precise controller response and high definition video and refresh rate. You will definitely experience issues when one or more of these processes are interrupted. When problems happen an internal inspection is necessary to identify where the problem is originating.


Error codes are a great advantage in diagnosing a problem. When the Xbox 360 shows a red ring of death (RROD) or the PlayStation 3 has a yellow light of death (YLOD), there will be a problem booting the system. It is not an indication of what is going wrong, but that there is a general failure and as a failsafe it will not boot. When a console does not boot there will be no display on screen and thus no identifiable error code. This feature of a light pattern indicator informing the user that there is a general problem has been carried over to the current gen consoles with Xbox one's orange light of death (OLOD) and PlayStation 4's blue light of death (BLOD). Don't let the use of the word "death" scare you, it can be resurrected, it just needs to see a technician to address the internal issues.

Data Recovery from iPhone With Damaged Mainboard

When your iPhone mainboard is damaged, you haven't synced your iPhone's data with iCloud, AND you consider that data to be vital business information or irreplaceable nostalgic photos and videos (for example) -- you may not yet be completely out of luck!

There is more than one approach to go about recovering data from a damaged iPhone. 

1. The iPhone doesn't work but powers on to the point where when interfaced with a computer and software data recovery is possible.

2. Repairing the mainboard damage sufficiently to allow access to the iPhones memory and using a host computer and data recovery software.

3. Removing the onboard storage integrated circuits and recovering data from the onboard flash storage using a specialized iPhone flash IC host. 

Bring your damaged iPhone in to us and we will determine the best (if any) method to recover your iPhone data. 

iPhone Wont Turn On Due To Mainboard Damage

An iPhone that doesn't turn on after damage to the mainboard as a result of an impact, liquid exposure, heat etc. is not necessarily bricked forever. 

Depending on the circumstances that led to the damage there may be a short circuit, an open circuit that should otherwise be closed, or a capictor or other surface mounted 'power-management' component may be damaged.

Extensive testing using microscopes and infrared heat sensors to specifically identify the damage, and subsequently repairing circuits or replacing components with micro-soldering and reballing tools is required.

The entire process of repairing an iPhone that has mainboard damage preventing it from powering on can take several days.

iPhone iTunes Error 4013

The most common question asked by iPhone users finding themselves in this situation is "Can I get my iPhone working again AND save the data?"

When the cause of the 4013 Error (Cannot Restore iPhone) is mainboard failure there is no way to restore functionality while also saving the data on the iPhone.  

The NAND chip (integrated circuit or IC) requires reprogramming which will - while restoring functionality - will also restore your environment to factory defaults, with no data.  

iPhone Back-light Problem Caused By Mainboard Damage

There are several possible reasons (other than a failed or broken display assembly) for a dim backlight or no backlight at all:

  • Long Screw Damage

    • Sometimes an inexperienced home-technician or Do-It-Yourself enthusiast undertakes to replace their own iPhone Screen.  If they have not been very careful to put the same screws back into the same places a long screw may be tightened in where a shorter screw rightfully belonged.  This error may result in the longer screw having been driven down into the traces on the logic board causing a short-circuit or a broken circuit.

  • Diode Failure

    • Diode failure may happen as a result of the drop that broke the iPhone glass and (not obviously) also caused internal damage. It is not unusual for this failure to become evident until after a new screen has been installed.  This component replacement may accompany long screw damage.
  • Backlight Coil Failure

    • The least often culprit and usually a by-result of other damages -- still requiring surface mount logic board component replacement in such circumstances.

Here is an example of a logic board repair on an iPhone X that won't power up:

Macbook Logic Board Replacement and Repair

If we find that a logic board issue has a cost-effective repair solution, we can attempt to perform the approved repair. Generally, we need anywhere from 1 to 10 days to complete the repair, depending on the complexity.

For liquid-damaged devices, we do undertake cleaning of the logic board upon customer request. If the logic board can be reliably cleaned and we think the device can potentially be saved, we proceed to provide an estimate for repair. No warranties are offered for repairs on a liquid-damaged device. Please read our comments on the subject before bringing the device in.

We do not have access to new logic boards from the original manufacturers since we are not the authorized service centre for any vendors/brands/OEMs.

We do not carry any logic boards in our inventory, yet would be willing to source used/refurbished logic boards in the open marketplace (ie. eBay, Kijiji, etc on the internet) upon user request and after obtaining a deposit in advance. Sourcing logic boards can take from 2 to 4 weeks and can cost from $300 to $800 (including parts and labour). Also, we do not warranty these used/refurbished logic boards, since these are sourced from anonymous third-party sellers.

However, if you'd like to provide us with your own logic board, we would be happy to replace it, only charging you for our repair labour charge. Again, we cannot warranty the outcome of this, since we cannot warranty a part that we have not sourced ourselves.

Bottom Line: Unless the logic board can be repaired, we suggest that you contact the manufacturer of the computer/laptop for the logic board replacement.

Laptop Logic Board Solutions

Laptop Data Recovery

Laptops come in a variety of sizes with different interfaces and performance ability. Since the first portable computer, The Osborne 1, released in 1981, there has been an enormous amount of development, adding new features and accessibility to the world of mobile workstations.

Although laptops have come a long way from their first models (which weighed 23 pounds), the primary electronic components function exactly the same. All computers require a central processing unit (CPU), memory, graphics processing, power source, a display and a method to interface with it (ie. mouse and keyboard). Modern laptops typically have all these components mounted together into one convenient portable unit. Just like any other electronic equipment, if one of the major components don't function properly then the entire system will experience problems.

In order to pack all the state-of-the-art features into one unit, circuit boards have become increasingly more condensed. Utilizing smaller components, integrated circuits and multilayered circuit boards, which sandwich additional copper layers between layers of insulating material, all sorts of newer technology can be crammed into something we can carry in one hand. After more than 30 years, these portable computers still use a central circuit board which connects all the major components and interface devices. We call this circuit board a logic board (or less commonly known as main board or motherboard).

Laptop Logic Board Repair

When an internal problem arises, however, it is far less convenient to access the logic board than it is to carry around. Most issues with laptops require a teardown of the many tightly packed components, logic board repairs demand complete disassembly. 

Check our Data Recovery Solutions page for laptops when getting your laptop running again is secondary to recovering the lost data. If you're guilty of not backing up your important personal data and your old laptop is ready for the scrap heap, then it is abundantly clear that you need to restore your lost data before losing it forever.
