Hardware and Software of Phones

Mobile phones have two options when it comes to repairing. There is a software side and the hardware side.

The software side is when every fault is worked on using a computer, a box, Internet connection, cracking and others while the hardware part is when everything has to be worked on manually by way of replacing parts using the different tools as seen above.

Phone Hardware

As seen mentioned above, those are some of the parts which can be worked on and or solved by way of doing things manually. They include replacing of the different ICs using the special tools and or cleansing.

Main Hardware Parts of a Mobile Phone

Different phones are made differently but, all of them do share almost the same parts when features and specifications are not put into consideration. Below are the different parts.
• The Microphone
• The Ear piece
• The Ringer aka Loudspeaker
• The screen (LCD)
• The Touch screen
• The Vibrator
• Keypads (keys)
• Antenna

• And many others.

Please note that each of the above has its own work and function where by when it’s faulty for example, the related task won’t be performed and which may make the phone unable to do the required work.

Part work, fault detection and repairs:
Now we should look on how to repair the different parts of the cell phone and how to tell that they are faulty and need repair.

The Microphone

The main work of the microphone is to exchange sound (words) with the other party during a call. The microphone records what you say and transmits them to the other calling partner. The mouth piece is located in most cases at the bottom side of your cell phone.

Fault detection:
When microphone or mouse piece is faulty, it won’t be able to do the transmission and usually, you will not be able to listen to the other person assuming he or she is the one with a phone with a fault mic, and or, he or she won’t be able to hear you assuming it’s your phone with a fault.

Repairing:
Depending on what the fault is, you may need to resolder the microphone wires if they are broken, and or to simply replace the old microphone with a new one. Microphones are sold in tech shops which sell phone spares and you can buy it at a price which is determined by your phone type and mode. You will need a soldering wire and a soldering Iron for this work. A meter is useful to help in detecting whether the mouth piece is completely dead of work-ing. And please note that before thinking of replacing or doing anything else, it’s advisable to ensure whether it’s working or not since they may be additional reasons for It not to work.

The Ear piece

The Ear piece does capture incoming voice and sound from the other part that one is taking to. And usually, its located where on the top center of your phone where many usually put the ear when speaking with another. When you receive a call or make one, the ear piece is the one which help you here the ring and or voice of the other.

Fault detection:
When the ear piece is faulty, it won’t be able to do the transmission and usually, you will not be able to listen to the other person assuming it’s your phone with a fault.

Repairing:
Depending on the kind of phone, you should begin by testing the earpiece using the testing meter. Once you confirm that It’s not working, and then you will simply need to purchase a new part (ear piece) and replace It. On the other hand, if its measuring but not working, you can clean up the seater and or consider looping if It’s a broken line.

The Ringer

The ringer Just like the names works as an alert when there is an incoming call. When someone dials your number, it’s the ringer which makes the sound to let you know. The same ringer works as aloud speaker when It’s activated during a call. It is also used when playing music, watching TV, listening to Radio and others.

Fault detection:
When your phone stops ringing and also playing music with no headsets inserted, It’s a sign that the ringer is fault. You can also try the settings page/profiles and see if the ringer is set to off or on and if on, then it’s a sign of it being faulty.

Repairing:
You need to use a meter to test it and confirm whether you should replace it or not. if its fault, then you need to buy the same part from the phone spares shop and replace it. However, if It’s measuring but not working, you can clean up the seater and or consider loop-ing if it’s a broken line.

The screen (LCD)

The LCD is the one through which we are able to see the different features of the phone and a sign that the phone is working. The LCD has lights which help one to see even during the night.

Fault detection:
If the screen stops showing, is damaged with a crack and or shows by faded, chances are that it’s faulty.

Repairing:
You need to use a meter to test it and confirm whether you should replace it or not. if its fault, then you need to buy the same part from the phone spares shop and replace it. How-ever, if it’s measuring but not working, you can try to do the following below;
• Clean up the screen connectors.
• Replace the screen fiber.
• Replace the screen ICE
• Perform Jumping (looping).

You should note that different phones have different screens. There are those which are simply plugged on, those with a fiber, those which simply sit on the connectors and others. You should ensure that you check the type of screen and perform the necessary tests before replacement since It may not necessarily be the screen depending on the fault. A soldering Iron and wire are commonly used when mobile phone screen repair perth.

The Touch screen

Most new phones and models have touch screens. The touch screen Is used to tap anything just like how keys on the old keypad styles do for example when making a call and one has to press a number, or to recharge with a card.

Fault detection:
When you can’t do anything on your device using the touch, I mean when the touch is not responding however much you try touching It, chances are that it’s faulty. Use a meter to test and confirm.

Repairing:
With Touch screens, all you need Is to buy the new touch screen and fixing it using either a plug connector and or using a soldering iron and wire. You can too replace the related IC as-suming the touch itself is okay, and or loop it.

The Vibrator

The Vibrator Is an additional alert when there is an incoming call, and or as set by the user through the settings. Usually, the vibrator rotates every time it’s triggered (on an incoming call or an alert).

Fault detection:
If there is no vibration, then chances are that it’s faulty. You can also try the settings page/ profiles and see if the ringer is set to off or on and if on, then it’s a sign of it being faulty.

Repairing:
Begin by measuring and confirm that it’s faulty or working. It’s measuring positive but not working, you can try to clean up where it seats and replacing the IC. If on the other hand it doesn’t pass the test, then you will need to replace It with a new part. Vibrators are mostly plug-in and play. There are too those which come attached to the ringer where by you need to buy all at once.
