Buying a Moto X Printed Circuit Board

Smartphones are complex, detailed machines made of many miniature and necessary parts, and the printed circuit board inside your Motorola Moto X is no exception. The circuit board acts in the same way as a CPU does in your computer; it makes sure all the necessary information gets everywhere it needs to be, so it's responsible for every task your phone does, from downloading apps to responding to your touchscreen. It goes without saying it's essential, and it requires immediate replacement when it breaks down for your phone to work normally.

When Should You Replace Your PCB?

Since you can't see inside your phone, you probably don't know when to replace this tiny printed circuit board full of electrical circuits and wiring. Fortunately, there are a few symptoms of a faulty printed circuit board that may alert you to take a closer look at this component.

  • Since some PCBs literally burn out, a burning smell can sometimes indicate that the PCB is past the point of use. With a few smartphone tools, you can open up your Moto X and do a visual inspection to look for crispy components.
  • When you turn your phone on, nothing happens. Not only that but when you plug your phone into a charger, the LED lights don't come on and there's literally no sign of life (and if there were signs of life, it could just be a battery issue). This could mean your printed circuit board requires a replacement.
  • When you feel like you have the technical skill, you can use certain testing equipment to test the PCB to see whether the component requires replacement.

How Do You Buy the Right Printed Circuit Board?

A PCB looks like a miniature motherboard that's mostly made of copper. Since these components are so specific, you'll need to ensure you have the right one for your Moto X.

  • Also called a motherboard or a logic board, your phone's wiring board has its own model number, and this model number should match the model of your phone. For example, the XT1049 PCB fits the Motorola Moto X XT1049 phone.
  • When you are buying a used part, you'll want to ensure that it's in proper working condition. There are OEM parts as well as third-party parts, so choosing one is a matter of personal preference as long as you get the correct one.
  • Make sure the component is unlocked, meaning it's not tied to any specific carrier and you can use it with any carrier you like.

Which Tools Do You Need to Replace Your Circuit Board?

Replacing a PCB does require some specific tools and a level of comfort when it comes to fixing electronics.

  • You'll need to remove the SIM card from your phone and to do that, you'll need a SIM-card removal tool.
  • Pry tools like a spudger let you remove the back housing from the front housing of your phone.
  • Screwdrivers and tweezers are necessary to remove small screws and move small, delicate parts around without losing them.
