I want to learn how to repair electronics and household appliances. How to learn to repair cell phones yourself

Many people often ask how to learn how to repair cars. Don't worry, friends, I have the answer to your deepest question.

The fact is that if you decide to become an avid auto mechanic, you will often be faced with difficult choices, for example “Hmm, should I go take a shower and change into clean clothes now? Although, I’ll 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. You meet your friends along the way, who then call your wife back and ask why she kicked you out onto the street and doomed you to be homeless. But these are all minor things.

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

1. Buy yourself a junk car

Want a crash course in car repair? Buy it for yourself. The best way learning how to repair cars consists of studying their structure. Especially if you are young and don’t have extra money to repair your car. Perfect option.

Many excellent craftsmen did not even know how to change oil or spark plugs until they were twenty years old. But then they bought a car that was older than themselves and began to rebuild it, thus learning the art.

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

2. Buy a tool kit

You can’t unscrew the nuts by hand, especially if they’ve been 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 don't have any money at all, you can go to FixPrice and look at something there, but don't count on such tools to last long. 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 pimped car, you can always gain a certain set of knowledge from training videos.

It’s hard to count how many videos I watched in search of answers to my questions about car repairs. In fact, their range is simply huge.

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

4. Buy a repair manual

A very useful thing. Step-by-step instructions for repairing your car will help you deal with any problem. They are not expensive, and if you are ready to read from the screen, you can even download one for free on the Internet. These books will save you a lot of time and effort.

5. Register on the forum

Most useful information can be found on the forums. Dozens of knowledgeable guys share their experiences, photographs and step by step instructions. In addition, they will tell you how to do this or that job while losing as few fingers as possible. Useful thing!

6. Help your friends

Has your friend's car broken down? Help him quickly. You will gain invaluable experience and establish yourself. Plus, if something ever breaks down for you, your friend will be more willing to come to your aid.

7. Talk to sellers

Aftermarket parts often employ hardened auto mechanics who can give you any advice. Don't underestimate their talents.

If your fuel pump is bad, go to the market and chat with the seller. He will tell you how to replace it, what parts you need and maybe give you a small discount.

But you shouldn’t rush 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 mechanic is visible at first glance (see point 1).

8. Sign up for a mechanic course

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

9. Read books

Buy or download several books on mechanics and electronics. After reading them, you will become much clearer about how your car works. Once you figure this out, repairs will no longer be a problem for you.

10. Read auto blogs

For example, CARAkoom.com. Every day we post a lot of interesting material dedicated to the world of cars. In addition, our regular columns about the structure of various parts of a car, for example, or, will help you easily understand the basics of the structure of cars. We try to use the most understandable analogies to explain complex automotive concepts. We also have one where you can gain a lot of knowledge and ask questions to knowledgeable people.

Quantity electronic devices is growing every year at an unprecedented rate.

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

Where to begin

Correcting problems with electronic devices is a delicate thing, and 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;
• metal resistance;
• inductance, etc.

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

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

If the electronics do not turn on

When connected to the electrical network, the device does not work, no LED signals are activated or no sound is produced, the reason for this is a burnt-out power supply. Try connecting the device in series with a powerful incandescent lamp to prevent a short circuit. When the power supply is running, the lamp will not light up, but if there is a short circuit on the power supply, the lamp will light up.

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

Incorrect work

If your electronics work intermittently, periodically giving a problem, there are many reasons for this operation. For example, when the computer turns off when the computer is under load, and after some time it works again, the fault may lie in overheating or damaged contacts.

In this series of articles you will learn:

• What knowledge and skills are needed to carry out repairs?
• How much does the repair cost?
• How much do master finishers earn?
• Where can I learn how to do repairs and decoration in Moscow?

Everyone faces the need for repairs sooner or later. The need to live in a neat, functional and cozy 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.

Benefits of DIY repairs

If you need repairs, there are several ways: contact a repair and finishing company, hire a private craftsman, 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 obtain a guarantee that all purchased materials were used for their intended purpose. Knowledge of the market, understanding of pricing and correct finishing technologies 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 of finishing work will not require a lot of time and money, but will help you choose the right materials, avoid mistakes and unnecessary expenses, and as a result save significant money. In addition, you will have truly in-demand skills that can become a profession and bring a good income!

First step: theoretical foundations of repair

First, decide on the budget and scope of work. We still recommend leaving highly specialized tasks, for example, installation of internal communications, wiring design and cable laying 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, set aside a few days to visit construction centers and hypermarkets and compare prices. Then conduct research on 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 finishing materials market: primers and moisture-proofing compositions, dry mixtures for putty and plaster, paints and varnishes, adhesive bases, various types of finishing;
• Selection of facing materials and their characteristics: plasterboard, floor and wall tiles;
• Ability to read and prepare 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 per square meter of area;
• Knowledge of safety and fire precautions.

Step two: what practical skills are needed for repairs?

To get an initial idea of ​​the stages of work, you can contact several repair companies to create an estimate. This service costs a symbolic amount or is completely free, but you will learn the opinion of professionals, discover places that you did not take into account, and compare cost estimates from different companies (they may differ by an order of magnitude).

Let's assume that you decide to do the repairs yourself. To do this you will need the following skills:

• Dismantling and preparatory work: cleaning the walls from the remnants of the previous finish, treating them with moisture-proofing compounds, thermal insulation, applying primer and markings;
• Rough finishing: leveling walls and floors, sealing cracks and joints, puttying surfaces;
• Finishing depending on the selected materials: working with dry plaster mixtures, painting and varnishing, wallpapering, tiling or frame-cladding work (gypsum board).

Articles and Lifehacks

In this article we will look at the basic part of how to learn how to repair Cell Phones on your own.

Your first step on this path is to purchase a tool, without which repairs will be impossible. Of course, these are screwdrivers with different tips. Cross slots on screws are rarely used, for example, in Samsung models.

In other phones, as a rule, star slots are used. Nowadays it is not difficult to find such screwdrivers. You need tweezers for working with small parts and a brush for cleaning. A soldering iron and a hot air gun will be needed for complex repairs.

Learn to look soberly at the work ahead of you. Without some experience, it is better not to undertake the repair of a device that requires replacing parts using a hot air gun.

First stage of training

• At the first stage of training, it is better to take phones from the “unrepairable” category. Such devices can be borrowed free of charge from the workshop.
• They practice the skills of disassembling and assembling a phone, starting with removing the cover, all parts secured with screws, boards, cables, and displays.
• Get into the habit of putting all your fasteners in a small box, preferably one with compartments for sorting screws. Place it away from the edge of the table so that you don’t try to pick up screws from the floor with a flashlight.
• There should be no unnecessary objects on the surface of the table, only a tool, a table lamp and, of course, the device being repaired.
• Also, do not forget to write down and sketch all the stages of disassembling the device. Until you gain confidence in your abilities and knowledge of the design of various models, do not undertake the repair of sliding and folding models.
• Your rule should be: if you’re not sure, look on the Internet. When washing the phone, under no circumstances should alcohol get inside the display backlight units. It is impossible to remove the stain that appears after this.

Moving on to real repairs

• Start real repairs only after you are confident in disassembling, assembling the phone, and replacing its removable components. First, try to repair devices that you don’t mind ruining.
• Make sure that the cause of the failure has been correctly identified and the repair has been completed successfully.
• Having learned how to restore removable components, you should also, for more complex repairs, master the work of replacing microcircuits and other components on boards using a hot air gun. During this work, the display must be removed.
• But it’s quite difficult to gain the skills to work with a hot air gun on your own. Therefore, it is advisable to replace the microcircuits and restore its fastening after training from a specialist.
• There are also specialized courses. Their cost pays off within six months.
