I want to learn how to repair electronics and household appliances. How to learn to repair cell phones yourself. In this series of articles you will learn

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 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 have absolutely no money, then you can go to FixPrice and look at something there, but do not count on such tools to last a long time. 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.

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 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. 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 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 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 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.

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?

This means that the repairman must know in general terms how it works operating system(OS) of the computer, office programs (text editors, Email, 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 novice, knows how to select the OS boot source or service programs (HDD, 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).

You can get acquainted with the structure of a computer and its components 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 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 malfunction 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 methods for eliminating 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 language, 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 workplace consider yourself 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 it works and how it works computer hardware. 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!

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 table surface, only tools, desk 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.

Do you want to learn how to repair a car yourself? Can you imagine how cool it will be to fix the problem yourself? But at the same time, you are not confident in your abilities, do you think that you are not capable of learning the science of auto mechanics? Put your doubts aside, if you really want to learn how to repair a car, you can do it!

You need to start step by step. Of course, you shouldn’t immediately try to remove the gearbox from the car and try to fix it, this will not lead to anything good. It’s the same as if in middle school they start teaching you the Laplace transform instead of elementary mathematics. Illogical, unreasonable, you simply won’t understand anything and will waste many hours.

If you really want to learn, start with the basics.

To get started you will need:

Patience and perseverance. Study the material you will have to work with. Step by step, each step, one after another.

Buy tools. Expensive professional kits are not necessary, just enough tools entry level(not outright junk, of course, but decent cheap tools). Maybe you won't like climbing in the oily insides of your iron friend in the end. In this case, why overpay?

And lastly, but most importantly, where to start? We invite you to familiarize yourself with five interesting and at the same time easy repair options that will teach you the basics of working with a car, in case of incorrect actions will not cause serious damage to the car and will certainly give you moral satisfaction from the fact that you were able to do it yourself.

If you get involved in the process and with constant practice (for example, you don’t have new car, requiring constant repair), then in a couple of years you will have a fairly good knowledge of the structure of your car, understand which bolt is responsible for what, which lock nut performs which function and what parts these or other systems consist of.

And it can all start with five simple renovations.

Replacing spark plugs

The advice does not apply to owners, because it is more difficult to change spark plugs on their boxer engines than to replace a worn clutch disc on other cars. Boxer engines are capricious in this regard. It is necessary to do a lot of difficult and, in a sense, jewelry work to unscrew all the candles, and most importantly, to correctly install new ones. These are the costs of the “boxer” design. In our case, it is better to turn to professionals who, with the help special tool and the accumulated experience will replace your old parts with new ones.

But if you're not driving a Subaru, then it's time to take action! For work, purchase:

Ratchet wrench

Extension

Spark plug head (3/8 inch twelve-point)

1. Remove the spark plugs.

Carefully disconnect the wires from the spark plugs. Take a socket wrench with an extension and a ratchet, slowly begin to unscrew the spark plugs counterclockwise.

2.Do not mix up the wires

If you have, label each wire so that you do not confuse the order in which they are connected to the spark plugs. Or change the spark plugs one by one: unscrew them, install a new one, connect the terminal.

3.Installing a new spark plug

It is very important to choose the necessary ones that are suitable for the specific make, year and model of the car. Consult your owner's manual or brochure from an auto parts store.

To make sure you don’t make a mistake, you need to take exactly those models of spark plugs that are already on your car.

Using a spark plug head, tighten the spark plug 1/8 of a turn, not with too much force, or use a torque wrench, having previously found the data on the tightening force of the spark plugs. Overtightening can lead to the destruction of the threads in the engine, and this is very bad.

Changing the air filter

Replacement air filter is one of the easiest jobs on the list. It is easy, quick and cheap to replace on almost any car, partly because filters have to be changed frequently, every 10-15 thousand km on passenger cars, access to it has been made as convenient as possible.

On most cars, you won't need any tools at all to access the air filter. Just unfasten a few latches, remove the top cover of the air filter box (check with technical documentation, manual, so as not to be mistaken where the filter box is located), and now you have access to it.

On some modern cars, the filter box is screwed on instead of latched. So take a screwdriver, remove the screws, and you can easily carry out the replacement procedure.

It is physically very difficult to confuse the location of the filter element in the box. But just in case, read the manual for your car about how the filter should be positioned correctly. After reading, act.

Changing the engine oil

When you imagine someone servicing a car, the picture that probably comes to mind is changing the oil. This is the most classic of points. Maintenance, and it is also one of the most important.

The oil is changed during maintenance once every 12 months or upon reaching a certain mileage recommended in the operating manual (10-15 thousand km), whichever comes first.

It is preferable to change the engine oil in a pit or in a garage equipped with a lift. *

*Take precautions, always put the car at speed or on the handbrake!

To replace you will need:

The head of the key for the drain plug of your car

Ratchet wrench

Filter puller (available at auto parts store)

A container where you will drain the used oil (the container, of course, should be larger than the capacity of your engine)

And of course, to replace it you will need the oil filter itself.

It is important to know:

Before changing the oil, you should drive the car for a short time. Thus, the entire suspension of foreign particles will be in the oil volume, and when it is drained, the engine will be better cleaned.

1. Unscrew the oil filler cap. It is located at the top of the engine.

2. We climb under the car and unscrew the drain plug with a wrench, having previously placed the prepared container. *

*Precautionary measures. Avoid getting engine oil on you. It is hot after the engine is running, so you won't get burned. Use thick rubber gloves when unscrewing the cap.

3. Draining the oil is a slow process, so while it is draining from the engine, you have time to remove the oil filter. Usually no tool is required for this. We find the filter and unscrew it manually. There are times when he does not leave his seat. Then we will use a puller previously purchased at the store.

Many modern engines have paper oil filters, which can be easily accessed with a socket wrench. Just unscrew the cap and your oil filter is in full view.

Apply some used engine oil to the new filter's O-ring and install it. Carefully read the instructions on the filter for its installation.

4. Oil glass. We tighten the drain plug. You shouldn't pull it very hard, there is a risk of breaking the thread. Screwed in all the way, tightened a little.

Uploading something new engine oil into the upper neck through a funnel. Fill in such an amount of oil that the level on the oil dipstick is between the “Min” and “Max” marks, a little closer to the second mark. Close the lid and start the engine.

Necessarily! After the first trip, check the oil level. It is ideal to watch it on a hot engine 10 minutes after stopping the engine.

Replacing an incandescent lamp

How many people does it take to ? This joke has a considerable amount of truth. The simplest task can turn into a serious headache. On some cars, to change one light bulb, you literally need to disassemble half the front of the car.

In other cases, replacing a light bulb is not a troublesome task:

IMPORTANT! It is necessary to choose the right light bulb model. To do this, we remove the burnt out light bulb, take it to the store and use it to purchase a new one.

Changing brake pads

Replacing brake pads on a car is a bit more risky than replacing a light bulb. That's why HIGHLY RECOMMENDED For the first time, replace the pads with a knowledgeable person who, if something happens, can correct the mistake.

Before replacing the pads, watch some of the following videos explaining the principles of replacing pads on various calipers:

Thank you for your attention!
