How to learn how to repair cell phones yourself. How to turn into a car mechanic: some tips for those who want to repair a car on their own Learn to repair electronics where to start

The number of electronic devices is growing every year at an unprecedented rate.

So, the production of electronics in St. Petersburg can only please. However, no matter how high its quality, it can still break. Sometimes a breakdown can be corrected on its own, so there is no need to take the equipment to a service center unnecessarily.

Where to begin

Troubleshooting electronic devices is a delicate thing, and in order to learn how to do it yourself, you need some knowledge of physics, at least a school course.

You should at least have an idea of what it is:

current strength;
resistance of metals;
inductance, etc.

You also need to gain experience in soldering radio components, and learn how to use an electrical tester and multimeter. For repairs, you will need to purchase all the necessary equipment, and depending on the type of equipment being repaired, you will need to understand the wiring diagrams.

A lot of people think that fixing PCs is a workshop job. But even beginners can rest a computer at home without special skills with a minimum of equipment. By yourself, if you have a soldering iron, you can replace the capacitors. But if you need to replace microcircuits, if you do not have experience and equipment, it is not advisable to repair such a breakdown yourself.

If the electronics won't turn on

When connected to the electrical network, the device does not work, no LED signals are triggered or no sound is emitted, the reason for this is a burnt out power supply. Try turning on the apparatus in series with a powerful incandescent lamp to prevent short circuits. When the power supply is working, the lamp will not light, and in the event of a short circuit on the unit, the lamp will light up.

Then we look for a malfunction in the power supply itself. This could be a simple cable break or a blown fuse. If successful, we eliminate the problem by replacing new parts or soldering the broken ones.

Incorrect work

If your electronics is working intermittently, occasionally giving a problem, there are many reasons for this. For example, when it turns off during loads on the computer, and after some time it works again, the malfunction may lie in overheating or damaged contacts.

Sooner or later, everyone faces the need for repairs. The need to live in a neat, functional and comfortable space is inherent in people of all income levels. An entire industry is built on this need, including the services of designers, planners and specialists in the repair and decoration of premises.

Self-repair benefits

If you need repairs, there are several ways: contact a repair and finishing company, hire a private master, or do everything yourself. It would seem that in the first two cases, your task comes down to setting tasks and monitoring the work performed. However, there are pitfalls here. Finding competent and reliable contractors is extremely difficult even with a decent budget - the market is still filled with unscrupulous craftsmen who can disappear after making an advance payment.

In order for the work to be completed on time and in compliance with all requirements, you will have to spend a lot of time and delve into all the details. Extra numbers may appear in the estimate, and it is almost impossible to get a guarantee that all purchased materials were used for their intended purpose. Knowing the market, understanding pricing and the right finishing technology will be your advantage.

If you do the repairs yourself, you will have to approach the matter even more responsibly, but the effort invested will pay off. Professional training in the field finishing works does not require much time and money, but it will help you choose the right materials, avoid mistakes and unnecessary costs and, as a result, save significant money. In addition, your assets will retain truly in-demand skills that can become a profession and bring a good income!

The first step: the theoretical foundations of the repair

First, decide on a budget and scope of work. We still recommend leaving highly specialized tasks, for example, installation of internal communications, design of wiring and laying of cables to specialists. In order to correctly set tasks, before starting work, it is advisable to decide on functional purpose each room, the number and location of light sources, switches and sockets.

To study the market for materials and tools, take a few days to visit construction bases and hypermarkets and compare prices. Then conduct a study of professional forums for the advantages and disadvantages of certain materials. You can also gain this knowledge by enrolling in finishing courses.

The minimum amount of knowledge for planning and organizing finishing work includes:

Basics of design and zoning of premises;
Knowledge of the market of finishing materials: primers and moisture insulating compounds, dry mixes for putty and plaster, paints and varnishes, adhesive bases, different types finishing;
The choice of facing materials and their characteristics: drywall, floor and wall tiles;
Ability to read and draw up drawings and floor plans;
Knowledge of the classification and purpose of finishing, measuring, laser and electromechanical tools;
Knowledge of the basics of rationing and consumption of materials for square meter area;
Knowledge of safety and fire prevention measures.

Step two: what practical skills are needed for the repair

To get an initial idea of the stages of the work, you can contact several repair companies for an estimate. This service costs a symbolic amount or is free at all, but you will find out the opinion of professionals, find places that you did not take into account, and compare the options for estimates from different companies (they may differ by an order of magnitude).

Let's say that you still decide to do the repair yourself. To do this, you need the following skills:

Dismantling and preparatory work: cleaning the walls from the remnants of the previous finish, processing with moisture-proof compounds, thermal insulation, applying a primer and marking;
Rough finishing: leveling walls and floors, filling cracks and joints, surface putty;
Fine finishing, depending on the selected materials: work with dry plaster mixes, painting and varnishing, wallpapering, tiling or frame-sheathing works (gypsum plasterboard).

How much does a renovation cost in Moscow?

For those who hesitate between doing their own repairs and choosing outside contractors, we provide an overview of the prices for repairs.

Prices for repairs in Moscow:

Greetings friends!

Computers and other smart devices have become an integral part of our lives.

We have no idea how we used to do without them!

But the computer can pretty much spoil the life of the user if it breaks down.

The good news is that you can learn how to repair computers like you can do any other craft.

There would be a desire!

But a computer is a complicated thing, so a repairer must have knowledge in several areas.

Where do you start?

What does a computer repairer need to know?

A computer repair technician must be an advanced user personal computer(PC).

This means that the repairer must know in general terms how it works. operating system(OS) computer, office programs (text editors, Email, browsers, image viewers, etc.), be able to use the Internet.

Most often, they do not work with Windows of various modifications, office suite MS Office, Chrome browsers, Opera, Yandex browser. An advanced user, unlike a teapot, knows how to choose an OS boot source or service programs (HDD, flash drive, DVD drive etc.), see what kind of hardware (processor, memory, video card, etc.), find material of interest to him on the Internet, including computer repair.

Without this minimum, nowhere. But today it is taught even in high school! If you want to become a repairman but have skipped computer science classes at school, you can take an advanced user course.

What are the parts of a computer?

But being just an advanced user is not enough!

A computer repairer must know what parts a computer consists of, how they work, how they interact with each other. The best way to get started with computer hardware is on desktop computer , not on a laptop or tablet.

The desktop computer contains a separate system unit, monitor, mouse and keyboard.

Such a system unit can be easily opened and disassembled using a curly (Phillips) screwdriver.

Disassembling a laptop or tablet is much more difficult and requires a special tool.

The system unit contains a processor and memory, a video card (separate or integrated), network adapter for communication with the outside world (separate or integrated into the motherboard), DVD or Blue-ray drive (optional), (electromechanical or solid-state - SSD).

You can get acquainted with the device of the computer and its components on this site in the heading.

Note that I do not use unnecessarily complex terms (which are so frightening for beginners) and talk about difficult things simple human language.

To repair computers, the amount of knowledge must be large enough and it must be accumulated gradually. As an advanced PC user and knowing how the components of a computer work, you can go further.

What kind of malfunctions are there in computers?

There can be a great many malfunctions in the computer. But they can be roughly divided into two types: hardware malfunctions, hardware and software(software).

The hardware part is the very component parts of the computer that we have already mentioned.

Software is not only an operating system and office programs, but also drivers for various internal and external devices.

A driver is a separate program for the interaction of some part of a computer or a peripheral device (printer, scanner, etc.), embedded in the OS.

Without a driver, any piece of hardware - just a set of metal, plastic and electronic parts.

Now you understand why you need to be an advanced user and know how the computer hardware works and how it works? In order to find out where to dig in the event of a malfunction - in the direction of hardware or software.

The malfunction is usually accompanied by characteristic symptoms. For example, the computer "slows down", does not load, does not work, or. Analysis of these signs, knowledge of the operation of the OS and the "hardware" of the computer will help to form a troubleshooting algorithm.

For example, if it is impossible to print from a computer to a printer, but the print test of the printer itself is successful, then you should not immediately reinstall the OS, but first check the interface cable and the printer driver.

Various troubleshooting recipes can be found in the heading on this site.

Block and component computer repair

After you have accumulated a certain amount of knowledge, you can start practicing. Any knowledge without practice is dead and useless!

Novice repairmen usually start with block repair... If a hardware malfunction (motherboard, memory module, power supply, video card) is detected, it is replaced with a similar one.

The difficulty here is that this may require reinstalling the drivers or even the OS. In addition, in the event of a malfunction hard disk you can lose all your data, which is extremely annoying. To identify a hardware malfunction, appropriate tests must be performed - memory tests, hard disk tests, etc. Many modern computers(and especially laptops) already contains such tests.

Therefore, a novice repairman should study at least a specific User Manual.

There is also the so-called (manuals for repair and maintenance), which contain more detailed information and ways to eliminate typical malfunctions.

Note that the User Manual may not be provided to the customer upon purchase.

Service Manuals are most often on English language, therefore, knowledge of technical English is an extra plus for the repairman. At the same time, there are many online translators, which undoubtedly makes life easier for beginners.

But aerobatics is a component repair!

That is, replacing not the entire component of the computer, but some parts on it, for example, or capacitors on the motherboard or in the power supply. What does it do? With the necessary qualifications, repairs can be much cheaper, since a transistor or capacitor costs much less than motherboard or power supply.

But to reach this level, you need to know much more than all of the above! You need to know electronics at a good level, be able to use measuring instruments. This is also described on this site, in particular, in the heading.

If you have a desire - get acquainted, study. It's free!

Why learn to repair computers?

The number of computers and other smart equipment will only grow, so specialists in their repair will always be needed. This kind of service is now in high demand. So workplace Consider it assured to you!

Computer repair can be learned like any other craft. This site will help you with this. In conclusion, let us recall the good old truth - "education is a way that helps to overcome the vicissitudes of fate."

So, let's summarize. To learn how to repair computers, you first need to become an advanced PC user. Then familiarize yourself with how it works and how it works computer hardware... After that, you can start practicing. To master component repair, you need to study electronics, learn how to use measuring instruments and other auxiliary equipment.

The amount of knowledge that needs to be learned is large enough. But this is just like in any other profession! It is up to you to choose the profession of a repairman or any other. If you want to become a computer repairman - good hour!

And my site will help you!

Many people often ask how to learn how to repair cars. Do not worry, friends, I have the answer to your innermost question.

The fact is that if you decide to become an avid auto repairman, then you will often face difficult choices, for example “Hmm, is it worth going to the shower now and changing into clean clothes? Although, I will still get dirty with oil "... Or, for example, you get out of the workshop, all torn and dirty and go to the store for spare parts. On the way you meet your acquaintances, who then call your wife back and ask why she kicked you out into the street and doomed to homelessness. But these are all small things.

If you are ready to start this lifestyle, then sit back and get ready to listen.

1. Buy yourself a wreck

Want an express course in car repair? Buy yourself. The best way to learn how to repair cars is to study their structure. Especially if you are young and you don't have the extra money to repair your car. Perfect option.

Many excellent craftsmen until the age of twenty did not know how to change oil or candles. But then they bought a car that was older than themselves, and began to sort it out, thus learning the art.

Ask for advice from friends, from your father, from your grandfather. Learn the basics. Change oil, candles, air filters, look through the technical documentation and everything will go like clockwork. A rusty bucket will help you fall in love with cars and learn how to care for them.

2. Buy a tool kit

You cannot screw nuts with your hands, especially if they have already become rusty for ten years. Go to the store and invest in a good set of tools.

I advise you to start with a screwdriver and a rich set of replacement bits. If you have no money at all, then you can go to FixPrice and see something there, but do not count on the long service of such tools. I recommend immediately investing 3-4 thousand and buying a good, branded kit.

3. Watch videos on YouTube

Even if you don't have a wreck, you can always get a certain set of knowledge from the training videos.

It is difficult to count how many videos I reviewed in search of answers to my questions about car repair. In fact, the assortment of them is simply huge.

However, I advise you to be choosy and look at the reviews and the number of views, since YouTube is open to everyone. Therefore, if you see that the guy in the video cuts the clutch cable or breaks the brakes, then turn on your brain for a second and be aware of what is happening.

4. Buy a repair manual

A friend has a car? Rather help him. You will gain invaluable experience and prove yourself. In addition, if something breaks with you, your friend will come to your aid more willingly.

7. Talk to sellers

In the aftermarket markets, there are often hardened auto repairmen who can give you any advice. Don't underestimate their talents.

If you have a fuel pump screwed up, go to the market and chat with a salesperson. He will tell you how to replace it, what parts you need and maybe give you a little discount.

But you shouldn't throw yourself at every seller. First, make sure that he is well versed in his business, and then start a conversation. As a rule, a good auto repairman is visible at first glance (see point 1).

8. Sign up for courses in mechanics

It is not at all necessary to go to school and get an education, because today more and more private courses are being opened. Take a couple of lessons and you will learn a lot of new and useful things about the automotive world.

Articles and Life Hacks

In this article we will cover the basic part of how to learn how to repair Cell Phones on their own.

Your first step on this path is the acquisition of a tool, without which repairs will be impossible. Of course, these are screwdrivers with different tips. Phillips head screws are rarely used, for example, in Samsung models.

In other telephones, as a rule, splines "asterisk" are used. Nowadays it is not difficult to find such screwdrivers. Tweezers are required for working with small parts, a brush for cleaning. A soldering iron and a hot air gun will be needed for complex repairs.

Learn to take a sober view of the work ahead of you. Without some experience, it is better not to undertake the repair of a device that requires replacement of parts using a hot air gun.

The first stage of training

At the first stage of training, it is better to take the phones from the category of "non-repairable". Such devices can be borrowed from the workshop free of charge.
They practice the skills of disassembling and assembling the phone, starting with removing the cover, all the parts fixed with screws, boards, cables, displays.
Get in the habit of stacking all the fasteners right away in a small box, preferably with compartments for sorting the screws. Place it away from the edge of the table so that you do not try to collect the screws from the floor with a flashlight.
The table surface should not contain extra items, only a tool, a table lamp and, of course, a repaired device.
Also, do not forget to write down and sketch all the stages of disassembling the apparatus. Until you gain confidence in your abilities, knowledge of the design of various models - do not take on the repair of sliding and folding models.
Your rule should be: not sure - look on the Internet. When flushing the phone, never allow alcohol to get inside the display backlight assemblies. It is impossible to remove the stain that appears after this.

Go to real repair

Start real repairs only after you are confident in disassembling, assembling the phone, and replacing removable units in it. First, try to repair devices that you do not mind spoiling.
Make sure that the cause of the breakdown has been correctly identified and the repair has been successful.
Having learned how to restore removable units, you should also master the work of replacing microcircuits and other components on boards using a hot air gun for more complex repairs. During these works, the display must be removed.
But it is quite difficult to get the skills of working with a hot air gun on your own. Therefore, it is advisable to replace microcircuits and restore its fastening after training with a specialist.
There are also specialized courses. Their cost pays off within six months.
