PHONE REPAIR 2 (Earpiece Problem)

2. EARPIECE PROBLEMS

AND SOLUOLUTIONS 


Unlike mouthpiece, earpiece is the ear of every phone. It helps you hear the other caller. When the earpiece is faulty you can't hear others while making call. It may deteriorate gradually by working partially. It may also stop working automatically. Depending on what happened to your mobile phone.

4 Causes of Earpiece Problem

1. Setting

2. Liquid damage.

3. Dropping

4. Sound IC or CPU.

4 Solutions

Very important.......Before you open any phone for repairs please make sure you test it first. Very important because most users don't ever know that bad network can contribute to poor phone call experience. So if there is poor signal you may hardly hear the other caller.

Now let's go to the first step to take when a phone has earpiece problem.

1. First, check that the volume settings are okay. 
If the volume is okay then it is something internal, at this time you can go ahead to open the phone. If the owner told you that the phone drops you are setting that something is definitely wrong with the internal components.

2. (Technicians Only) Open and check if there is any abnormality with the earpiece placement or if there is any liquid damage sign.
If there is solve it. Your eyes has a major role to play in Technician work, repairing small/micro parts of cell phones. 
If not check if the earpiece speaker is still working fine. Do so by using a multimeter to test it.
Keep the multimeter in Buzzer mode. The value should be 25 --- 35 Ohms. If it is not within this reading change the Earpiece.

3. If the problem persist check the earpiece tracks to make sure they are okay, then you can do a jumper wire if any of the tracks are disconnected.

4. What if those areas are perfect? Go ahead to wake the Audio IC up. Hahahha! Does IC sleep? Yes! To me when they are not working properly they are as good as dead or sleeping. You can wake it up by Heating or Reballing it.
Last but not the least. If the problem persist go ahead to heat the CPU. If its still the same reball it or change it.

Note: Audio IC and CPU are the main control for earpiece in every device 

Trying any of the 4 steps above, can lead to smile and happy ending for both technicians and device owners.

Warning!
Be carful not to brake the phone
