I want to learn how to repair electronics and household appliances. How to learn to repair computers

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 condemned you to homelessness. 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. Ideal 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 oil, spark plugs, air filters, look through 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 various parts 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. Join us and you too will become crazy about cars!

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 start

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 all the 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 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 operation

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.

Greetings friends!

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

We can't imagine how we ever managed without them!

But a computer can pretty much ruin the user’s life if it breaks down.

The good news is that you can learn computer repair just like any other craft.

There would be a desire!

But a computer is a complex thing, so a repairman must have knowledge in several areas.

Where to start?

What does a computer repairman need to know?

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

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

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

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

What parts does a computer consist of?

But being only an advanced user is not enough!

A computer repairman must know what parts a computer consists of, how they are constructed, and how they interact with each other. The best way to start getting acquainted 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 Phillips screwdriver.

Disassembling a laptop or tablet is much more difficult, and you will also need 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).

Familiarize yourself with the computer structure and its components can be found on this website in the section.

I note that I do not use complex terms unnecessarily (which are so scary for beginners) and talk about complex things in simple human language.

To repair computers, the amount of knowledge must be quite large and must be accumulated gradually. Being an advanced PC user and knowing how the components of a computer work, you can move on.

What malfunctions occur in computers?

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

The hardware is the same components of the computer that we have already mentioned.

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

A driver is a separate program for interacting with some part of a computer or peripheral device(printer, scanner, etc.) built into the OS.

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

Now do you understand why you need to be an advanced user and know how the computer hardware is designed and works? In order to know where to dig in the event of a malfunction - towards hardware or software.

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

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

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

Block and component computer repair

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

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

The difficulty here is that this may require reinstalling drivers or even the OS. In addition, if there is a malfunction hard drive you may lose all your data, which is extremely annoying. To identify a hardware malfunction, you need to perform the appropriate tests - memory tests, hard drive tests, etc. Many modern computers(and especially laptops) already contains such tests.

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

There are also so-called (repair and maintenance manuals), which contain more detailed information and ways to troubleshoot common faults.

Please note that when purchasing a User Manual, the buyer may not be provided with it.

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

But the aerobatics are component repairs!

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 this give? 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 have a good knowledge of electronics and be able to use measuring instruments. This is also discussed on this site, in particular, in the section.

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

Why learn computer repair?

The number of computers and other smart equipment will only increase, so specialists will always be needed to repair them. This type of service is now in great demand. So, consider your job guaranteed!

Computer repair can be learned just like any other craft. This site will help you with this. In conclusion, let us recall the good old truth - “education is a way to help 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 get acquainted with how computer hardware works and how it works. After this, 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 quite large. But it’s like in any other profession! Whether you choose a repairman profession or any other is up to you. If you want to become a computer repairman, good luck!

And my website will help you!

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 finishing works 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 the functional purpose of 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 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).
