Advice 1: How to fix a phone screen

You dropped your phone and broke the screen. This can happen to anyone. Fortunately, the replacement screen in your phone is a relatively simple operation. All you need is the display and a special set of screwdrivers.
How to fix a phone screen
You will need
  • New display
  • Special screwdriver set
  • Jar for small parts
Do not panic even if your phone is worth several thousand. Display - not the most expensive part. Screens most phones are sold at a price of about 300 rubles. Only very large displays cost about a thousand rubles.
Take your phone to a store that sells spare parts for cell phones. Show it to the seller and he'll tell you what kind of screen you need and whether it is available.
If you are going to change the display independently, and the special screwdriver you have, purchase at the same store and their. In any case, do not attempt to open the phone in the normal screwdriver. You will ruin the splines on the screws, and then remove them will be impossible.
Do not place the screen in a pocket - it is very fragile. Bring it home in the package.
If you have even a little doubt in their abilities, better give me your phone and display in your nearest workshop. You will spend to replace it more money but the result will be guaranteed. If your phone has a touchscreen, it for the replacement display is better not to take even the most experienced house master.
Enter in a search engine query of: "how to replace display in (the model name of phone)". Find illustrated step by step guide to replace the display in your phone.
Select the screwdriver set bit corresponding to the slot type screws, used in your phone. Place it in a screwdriver handle, then immediately close the box from the set, so as not to lose other bits.Turn off the phone, remove SIM card and battery. Put them in a place where they will not be lost.
Examining the phone, exactly follow all the recommendations of the guide. All the details that are small enough, put not on the table, and in a jar. Otherwise, you can one careless movement to wipe them from the table onto the floor. This is especially true of screws. Make sure to note, the screws of which lengths correspond to which holes in the phone.
Replacement display in most cases is carried out without soldering, so soldering is not required. We perform this procedure carefully so as not to crush the new screen.
Assemble the phone in reverse order. Be careful to set in place all removed details.
Put the SIM card and the battery back into the phone. Turn it on and make sure the new display works. Also make sure that it continues to work all the buttons and vibrate, microphone, and speaker.

Advice 2: How to fix speaker

Almost all of us at home have speakers, a subwoofer or other device for transmitting sound to the speakers. And at least once during the operation of the dynamics fail. This happens because of violations of the climate regime, pollution of the speakers, their mechanical damage.

If you learn to deal with the cause of failure, then in half the cases you will be able to fix it. To fix the speaker can be quite simple screwdriver. Sometimes in the case are a soldering iron, extra wire, glue, gum and other unexpected materials. It is worth considering that modern loudspeakers have a fineness of organization, therefore, to fix them more difficult. On the other hand they are better protected, and it reduces the risk of breakage.

Here is a small list of breakdowns and ways of dealing with them.

  1. If the dynamics of the bent membrane, you can try to restore its shape. This should be done very carefully, as a disruption of the structure is irreversible and may worsen the situation.

  2. The membrane is attached to the diffuser, sometimes the problem of noise and rattles in it. It could be damaged. So you need to very carefully spin dynamics and replace the diffuser. Mending in such a situation is quite complicated, and then it's better just to replace the entire speaker.

  3. Problems can occur because of the clogging dynamics. Most often dust, rust or debris get between the magnet and the coil. This leads to the fact that the speaker starts to emit the "extra" sounds. Everything is simple. Gently rotate the housing and get to the speaker. Then wrap the match cotton soaked in alcohol and remove the debris. It is important not to disturb the wires and connection dynamics.

  4. If it was broken or broken wires that go to the cone, then you need to restore them. In this case, to repair the speaker only with a soldering iron. Failure becomes the result of constant vibration in dynamics, to prevent the wires need to be strengthened.

  5. One of the most difficult options is when the magnet dynamics "leads". Most often this happens because of the proximity of other magnets, temperature changes. Here is one recipe – replacing the magnet, and better dynamics overall. So how to choose a magnet of the same strength can be difficult.

  6. If you have violated the integrity of the "plate dynamics", you should try to replace it or to make these out of paper. The latter is very short-lived and uncertain.

In General, speakers repair is not difficult, important to have at least the basic concepts in the physics of sound and acoustics. If you want to avoid such trials, buy dynamics of the closed type, and in case of breakage just change them.

Advice 3: How to fix the microphone

Modern people without phones feel not comfortable, even if they almost never use.

However, the permanent contact with technology requires us to some new knowledge. That is, if you want to use technology, be prepared for the fact that you will need to learn how to do the basic repairs of their machines. The problem faced very often, it is a violation of the microphones in phones, headsets and microphones to computers. Note that to fix the microphone as a rule, not difficult, repair is elementary. However, most often we lose time, money and nerves to carry the microphone in the Studio.

There are three common problems that put the microphone down. If we consider the problem carefully, it can be solved independently.

  1. The microphone loses sensitivity because of clogging. Dust, microparticles of the skin, the COP gets on zvukousilitel head and that loses its properties. To fix the microphone in this case, need wool alcohol and a screwdriver. You need to release the microphone. To do this, sometimes you need to spin the phone or remove the cover with it. Then dip the cotton wool in alcohol and very carefully remove the plaque from the head. Keep the wool left on it. Let the alcohol evaporate and set the microphone back.

  2. The microphone loses sensitivity due to moisture. Sometimes between the gasket and the head is delayed condensation. Usually, the head does not rust, but the moisture does the job. You need again to release the head and to warm it under a lamp. If there are pads, the same should do and take off.

  3. The microphone fails due to rupture of the incoming wire. There are two options – change, or soldering. To apply them you need based on the specific situation. Phones, often need to solder the broken wire. With headphones, there are situations of violation of the wire in multiple places, then it's better to change everything.

If the problem is serious change the whole unit, especially when it comes to the phone. As for the set, then it is better to just replace it completely.
