简介

If you need to replace the power button on your Logitech G733 Wireless Headset, you can do so with this guide. Since getting to the power button requires taking off the circuit board, you can also access the scroll wheel using these same steps. For this guide, you will need a Phillips #000 screwdriver, a Torx T4 star-shaped bit, and a halberd spudger. The most difficult step is popping the plastic button off; make sure to do this step with care.

你所需要的

1. 步骤 1 Power Button
  Before you begin, discharge the headset battery below 25%. A charged lithium-ion battery can catch fire and/or explode if accidentally punctured.
  
  Gently start to pull the left ear pad off, starting from the top.
  
  Slide your finger around the edges until it releases completely.
  
  Remove the ear pad.

4. 步骤 3
  Gently lift off the speaker housing, with care not to strain the connected cable.
  
  Remove the screw on the bottom right-hand side of the motherboard using a Phillips #000 screwdriver.
  
  Use your thumb to gently pull back the tab at the upper right-hand corner of the headphone and simultaneously pull the circuit board out.
  
  The scroll wheel may fly out when you pop the circuit board out.

  Once the motherboard is loose, gently pull the wire out of its harness.
  
  The wiring harness is glued, so be careful with it. It should pull out easily.

6. 步骤 5
  在这个步骤中使用的工具：
  Halberd Spudger
  $2.99
  
  购买
  Pop the power button out of its recess by pushing it through the side of the headphone with your finger.
  
  Now use the hook end of the halberd spudger to pry the connecting piece of the power button off at the end furthest to the inside of the headphone.
  
  This step is the most difficult, so be careful when prying.
