Samsung do it yourself Samsung phone repair

They brought a Samsung gt – c3300 hello kitty telephone with an interesting defect, which I hadn’t come across before - it was that the device didn’t see the SIM card.

Well, well, we will disassemble such a pink mini device, probably aimed at children.

We remove the back cover, take out the battery - which in this model looks small, but has a capacity of about 1000 mA / h!

To disassemble the phone, you need to unscrew the screws, which, as it turned out, are also reinforced with sealant along the thread, so even a good screwdriver will be difficult to unscrew.

Next, by the mediator, we snap the case along the latches on the case, remove the iron protective screen from the special inserts in order to see the board.

So, we do not see protective filters - it is not peculiar mini fuses that are to blame, the soldering is intact, we inspect and stupidly see nothing, but if you look at a piece of the sticker on the protective screen, we find a piece of the leg from the SIM connector, which means it is damaged and the SIM card does not have contact as intended by the manufacturer with the phone diagram.

We are looking for a suitable connector, but nothing suitable is exactly found, we disassemble the old telephone that is not advisable to repair, namely lg gs101, and we solder the connector with a hairdryer in the holder on the back of the board, it is slightly smaller in size but fits in scale on the patient's scarf.

We solder the case only partially, and it holds perfectly at two points of support, we fix the lower three leads as expected, and extend the upper ones with copper tinned conductors, as expected.

We check a little by assembling the device in the reverse order - everything worked, now the device sees the master's SIM card and asks for a pin code! That's it, the repair is over, it remains to finally collect the pink apparatus! Author - Redmoon.

To begin with, it is strongly recommended that you familiarize yourself with at least the basics of radio electronics. The fact is that the repair of mobile phones is closely related to theoretical knowledge in this area. For example, if you need to replace a resistor (this is a passive current-limiting electronic component), then you definitely need to know its labeling, resistance, power dissipation, temperature coefficient, etc. With other owls, it is not very advisable to repair mobile phones without knowing Ohm's law. There are a huge number of books and manuals on the topic of radio electronics, as well as thematic sites on the Internet. But this is not enough. Mobile phones are digital devices, not analog ones. Consequently, all parts and components used for the production of the latter have differences among themselves. For example, for analog devices, surface mounting technology is mainly used, and for digital devices, surface mounting. The latest technology is called SMT (surface mount technology). It also translates as "surface mount technology". And the components used in this technology are called SMD (surface mount device).

Also, there is no analog signal in digital electronics, because it is actually digital. Consequently, all digital devices have their own types and levels of programming. These are just a few of the differences between analog and digital technology. But even this is enough to scare a newbie away. But there is no need to despair here. Everything is much easier than it seems. A lot of that frightening information is not needed when repairing mobile devices.But if you are planning to seriously tackle this business, then it is strongly recommended to study analog and digital radio electronics.

Now we come to the main goal of this article. So, now you will be described in detail the procedures for technical repair of mobile phones and types of repair devices.

In order to repair a cell phone, including repairing Nokia, Samsung, Sony-Ericsson, LG, Motorola, the first thing is to determine the cause of the failure of the mobile device and identify the component, assembly, module or part that has failed. For this, the knowledge that is described above is just needed. Usually, the breakdown of a mobile phone is caused by improper operation or loss of functionality of external devices. For example, in the first case, the phone fell into the water by negligence. To restore it, complete disassembly and thorough drying are required. After that, you need to use a soft-bristled brush to clean the phone's printed circuit board with a special cleaning agent or 96% alcohol solution. In the second case, the LCD, speaker, microphone, keyboard, etc. are out of order. As a rule, in most cases, such parts cannot be repaired and must be replaced. But if there is damage to the surface (soldered) parts on the printed circuit board, then a professional approach and experience are required. In addition, for this type of repair, you will need a diagram of assemblies, modules and components of the printed circuit board of a mobile phone.

In order to start the repair procedure, the phone must be disassembled.

To open a mobile phone without causing cosmetic damage to it, you need to acquire special tools for opening them. They allow you to open the phone case accurately and as efficiently as possible without causing defects. As a rule, these instruments are sold in sets, each item of which is responsible for its own specific opening. Such kits are not difficult to find in specialized stores. In addition, they come in various types. The difference is the functionality and the price.

You also need a specialized set of screwdrivers for mobile phones. You don't need to save on this. The more specific number of attachments you have, the more chances you will have to unscrew the screws without breaking the edges.

Further, in order to diagnose the phone for its malfunction, you will need a good digital multimeter. It can be used to measure AC and DC voltage and current, resistance, capacitance of capacitors, coefficient of transistors, diode state, continuity of circuits, sections of circuits or nodes, temperature. With skillful use and knowledge of some physical laws, they can find faults in the circuit. The range of multimeters is enormous. The difference is usually in functionality and price.

We also need a laboratory power supply or power supply. With it, it will be possible to set the specified voltage and current. You will need it very often when carrying out repair work, because it will be inconvenient to substitute the rechargeable battery for testing, over and over again. Modern power supplies are equipped with a current stabilization and protection function, as well as a large number of all kinds of clamps and probes for various cases.

Soldering equipment and fixtures. To carry out soldering work, you need a soldering station. Their variety is infinitely large, and the choice is determined by the price and functional range. There are combined soldering stations that combine both a heating soldering iron with temperature control and a hot air dryer, which also has the function of adjusting temperature and air flow.

A hot air dryer is usually required for mounting and dismounting SMD components, as well as integrated circuits made in a BGA package.

Also, when carrying out soldering work, you will need a device for the bottom heating of printed circuit boards. The fact is that when installing or dismantling, for example, integrated circuits (chips), there is a risk of overheating and failure. When using a heating device, on which the printed circuit board of the mobile phone is placed and fixed, the board is rationally heated. And already with a heated board, you can start assembling or disassembling components without fear of their breakage, because this procedure takes place in a few seconds.

Antistatic thermo-tweezers are also useful for soldering work. It is very convenient to use it to dismantle some of the components.

Since you will be faced with soldering work on the installation / dismantling of integrated circuits, you will need a vacuum manipulator. This device is manual and automatic. It is designed to place the chips with the contact pins on the surface of the printed circuit board of the mobile device as accurately, efficiently and conveniently as possible. It is inconvenient to do this with tweezers, especially since there is a high probability of “kill” the microcircuit with an uncalculated pressure. This will never happen with a vacuum manipulator.

Also in the work you need a desoldering pump. With the help of it, you can easily perform a desoldering by removing the molten solder.

Optics. Parts and components of mobile phones are measured in micrometers and nanometers. It is clear that working without special magnifying devices is very problematic and harmful to vision. In these cases, it is strongly recommended to acquire a 40 diopter technical microscope (not to be confused with a biological one). You will also need a backlit tabletop magnifier. It is not convenient to work with a microscope in all cases, and it is convenient to use a table magnifier almost always when ultra-high magnification is not required. Mounting magnifying glasses or forehead binocular glasses will also do the trick.

To carry out washing, cleaning of all kinds of components and printed circuit boards from dirt, oils, fats, solder, plaque and rosin, you will need an ultrasonic bath. It performs ultrasonic cleaning very effectively and safely.

Other tool. Among other installation tools and accessories, you will need a mounting fixing table, with which you can easily and securely fix the printed circuit board for repair work. Be sure to have a variety of tweezers, mounting awls, round-nose pliers, pliers, long-nose pliers, and wire cutters with you. You can add solder paste, flux, solder, rosin, cleaners, ultrasonic cleaner and other consumables to this list.

Where to get parts and components for repair? Of course, you can buy them in specialized stores, but it is best to buy broken phones. Since in some cases, it will be very problematic to find some parts, and it will not be difficult to buy, for example, a broken phone, which contains the necessary part, moreover, at a very low price.

Well, here we are with you and got acquainted with the minimum that a mobile device repair engineer should have. Of course, knowledge and experience will come with time, as theoretical and practical skills are developed. Read books on electronics, if possible, sign up for special training courses in the repair of mobile phones, communicate with people who have experience in this area, visit specialized forums on specific topics, where people are always ready to help.

In general, great success to you in your mobile phone repair business!

Using the Samsung U600 cell phone as an example, we will consider the most common breakdowns of these phone models. After a while, most of the phones of this model showed the following defect: the cable connecting the two parts of the slider was frayed. As a result, the image on the screen disappeared or just ripples appeared on the screen. Another defect: problems with touch buttons.

After some time, the camera stopped turning on and it became impossible to view photos in large size. In this state, he had to arrive for three years, until finally my hands reached him.

To repair my U600 phone I needed:

• Screwdriver Set,
• sharp knife
• tweezers,
• flex cable Samsung U600 connecting two parts of the phone.

In order not to loose the bolts, you can use a magnet. In my case, I only managed to buy a loop, although in a worse scenario I would have to buy a loop with touch buttons as well, but I managed to bring it back to life.

Recharge the battery before you start repairing your cell phone. After you have recharged the battery, remove the back cover and take out the battery.

Do not forget about one more important point when repairing phones, which the masters often talk about, is static electricity. They say that because of it, the failure of some elements of the phone is possible. And in order not to buy a static bracelet, we will recall the physics course and before disassembling the phone it is better to do a wet cleaning in the room, that is, to wash the floors and wipe the table on which the repair will be carried out with a damp cloth. At the same time, there should be no visible traces of water on the table. Such a procedure should be carried out after a while during the entire repair and you can not worry about static electricity.

We take the knife further and carefully pry off the cover under which the bolt is hidden. The master who repaired this phone for the first time unfortunately damaged the cover.
And unscrew the bolt.

Then we unscrew 4 more bolts holding the phone case. And taking hold of the part of the body in the area of ​​the flashlight, remove it.

The next step is to remove another cover from the end of the case, also prying it off with a knife.

And we unscrew the two bolts located at the edges and remove this part of the phone case.

Now we unscrew the six bolts that hold the case with the keyboard.

Disconnect the cable going to the keyboard and microphone by lifting the clamp that holds it and using tweezers to remove it from the connector on both sides.

Now we carefully take out the board and turn it over, where we can see the unfortunate loop due to which the phone's display did not work. With a knife, slowly from the side of the board, we pry the cable over the case with connectors. In no case should you remove it by prying it by the cable itself, since the case with contacts can come off the cable, and if the cable was new, it will become unusable. Having disconnected the ribbon cable, you can safely remove the board and the part of the case on which it was installed by pulling the ribbon cable through the hole.

Next, unscrew two more bolts on the other part of the phone case and move the metal part of the case as shown in the figure.

Now we remove the cable from the connector marked with number 2.

This disassembly of the phone Samsung U600 has finished the next step of the phone repair.

The assembly of the phone is carried out in reverse order, with minor nuances. Install a new ribbon cable in connector 2 and fix it with a latch. Now we take a part of the phone case, on which the sliding mechanism is installed, and by placing it vertically, we install the power button of the phone in its place. Holding this part of the case in the same position, take the second part, push the cable into the opening and align both parts of the phone case. In order for them to come together, you need to move the slider mechanism a little to the side. When both parts are aligned, tighten the two bolts.
The part of the phone with the display is assembled, we take the part of the case with the keyboard and push the cable through the hole in this part of the case.
We install the board on which the sim card is located and connect our cable from another part of the phone and the cable from the keyboard and speaker to it.
We tighten the body with six bolts to the sliding mechanism.
Install the lower part of the phone case and twist it. Then we install a decorative plug from the end.
We install the last part of the phone case in place and screw it on.
We install the SIM card battery and check the phone. If all the work is done correctly, the phone will work without problems.

"I do it myself - I'll tell you how to do it for you!"

If the breakdown of a mobile phone has ceased to be a hypothetical phenomenon, but has become a harsh reality, then it is important to make a fundamental decision - whether to contact a service center with your problem or to do the repair yourself. Each of these options has pros and cons.

There are many workshops that repair Samsung phones in Moscow. It is difficult to choose one that is trustworthy. Parting with your hard-earned cash to pay for the work of specialists is even harder.

But is there an alternative to contacting the service? Is it possible to repair a broken mobile with your own hands? And won't you have to take the faulty phone all to the same service after some time, only already disassembled, having spent a lot of time and money on ethereal attempts to rehabilitate it?

The answers to these questions depend on many factors. They often determine the final choice of the solution to the problem. First, it is important to consider the nature of the breakdown. If the phone breaks or falls, it is not advisable to take on the repair yourself. In this case, replacement may be required for most of the parts, the failure of each of which entails various malfunctions. Comprehensive repair of a mobile device can only be done by a qualified worker.

Of course, the failed parts can be purchased in the store, and the instructions for their installation can be downloaded on the Internet. Buying a set of tools for repairing will also not be a problem - the range of goods is quite wide. But, without experience of such actions, it is very difficult to get a decent result. And before starting work, you should assess the risks for yourself.

Dealing with software glitches seems to be an easier task. Its solution does not require the purchase of screwdrivers and wire cutters. But such work requires certain skills. To get rid of freezes, malfunctioning applications and uncontrolled restart of the device, you will have to update the phone software or reflash the device. Knowing how to do it and doing it yourself are two different things.

Secondly, you need to consider your phone model. There are devices, the design of which is simple and their repair will be successful even with a minimum of tools, knowledge and experience. But most modern mobile phones are complex devices. Their multifunctionality is provided by a variety of mechanisms. And by eliminating one defect, it is very easy to create another one yourself.

Worse, unskilled intervention can be fatal to technology. And even an iphone repairman from a specialized service may turn out to be powerless after carrying out amateurish upgrades.

In order not to find yourself in a similar situation, your strengths and abilities should be assessed with an open mind. And if there is even the slightest doubt about the success of your undertaking, then it is better to delegate some of the responsibilities to those who actually know what actions need to be taken in order for the phone to work and remain serviceable as long as possible.

After my daughter lost her smartphone, an old but very pleasant miniature slider Samsung E350 was taken out of the bedside table for her.

A couple of years ago, we put it aside, due to the failure of the screen. The screen worked, sometimes it didn't, and in the end it just glowed white. It is logical to assume that it was not the screen itself that was out of order, but the “wire” connecting the two halves of the slider. The internet says this is the most common problem with slider phones.

Of course, the simplest thing would be to take the phone to a service center. But, as we remember, “this is not our method”.
A couple of minutes of searching, and the online bazaar-auction produced a dozen compatible cables for Samsung E350, both native and Chinese. The range of prices is from 1 to 10 euros.

Well, for 10 euros (100 UAH) it makes no sense to repair it yourself - the same service center, so I ordered a “Loop Samsung E350 / E350E copy” for 1 euro (10 UAH) + 2.5 UAH delivery by mail :-). The letter with the train arrived in a couple of days. Now you need to disassemble the phone and replace the old cable with a new one. A short search on the net gave detailed instructions on how to do this.

From the tools you will need a Phillips screwdriver, scalpel and tweezers.
We remove the battery and use a Phillips screwdriver to unscrew the four screws circled in red.

Next, using a scalpel, release the side latches and separate the back part.

We take out the board from the case and disconnect the loop connector from the back side.

We proceed to disassemble the upper part, separate the slider mechanism, prying the guides with a scalpel.

Now we unscrew the four screws and also remove the cover with a scalpel.

The ribbon cable in the upper part is connected with the same connector as on the main board, without soldering. Therefore, difficulties should not arise. Moreover, the loop in this phone is one of the parts that often fail. Replacing it, as you can see, will not be a problem. You can just as easily replace the display, it is also connected with a similar connector, without soldering. There are cases of failure of the microphone, speaker. Everything is available for replacement after disassembly.

Everything is ready. We have disassembled the Samsung e350e phone.
(Instructions from the site mobiteh.com )

Now we insert our cable into the place of the old one and assemble in the reverse order.
Turned on the phone - the screen works fine 🙂
Of the costs - 12.5 UAH and half an hour to replace the train, but SEE of pleasure from self-repaired and returned to life things 🙂

Welcome to the section "DIY phone repair"! This section is a practical part of the BASICS OF ELECTRONICS resource.

Nowadays, a cell phone has become an integral part of our life; almost every person has this device! And some have two! And of course the phone, like any other electronic device, tends to fail. In this section, I will show in practice how to produce DIY cell phone repair specific models. Of course, the articles will be designed for radio amateurs and engineers who have some skills in soldering and know the basics of electronics and circuitry. However, the simplest repair of mobile phones with their own hands can be done by any ordinary person, without the aforementioned skills and knowledge. This, of course, concerns the replacement of some constituent parts of the phone.

I hope that the material presented on the topic of phone repair with your own hands will support the theoretical knowledge that someone may have already received on this Internet resource or from other sources!

In this article, I will tell you in detail how to properly stick a protective film on a phone (smartphone, communicator, etc.)

• material - universal protective film;
• phone - Samsung Galaxy GT-S5830.

In this article, I will introduce you nokia 6120 classic cell phone repair experience:

• external manifestation of a malfunction - the subscriber is not heard through the earpiece.

It happened that the touchscreen on the Samsung Galaxy S III Mini phone, dear to me, was covered with a network of non-decorative cracks. He took it to the workshop, they promised to do it quickly. The cost of repairs is 2500 thousand. But giving a third of its cost for repairing a phone is somehow silly.So, I'm changing the touch screen on my phone with my own hands.

He began by buying an original touchscreen in a telephone spare parts store for 560 rubles (he did not dare to take a Chinese analogue, although it is twice cheaper).

1. We also need small screwdrivers: regular and Phillips; a sharp object like a knife, you can clerical (I used a scalpel); medical gloves.

2. We disassemble the entire phone: remove the cover, take out the battery, SIM card, USB flash drive. Use a small Phillips screwdriver to unscrew the screws around the perimeter of the phone.

4. From the end, pry off the phone cover with a knife and separate the front wall from the back. We walk with a knife around the entire perimeter of the phone, disconnecting, removing two parts of the phone from the latches.

6. Now we need to disconnect all the cables on the board. Gently pry them with a small screwdriver (as in the photo).

7. After the cables have been disconnected, we hook and remove the board.

8. Unscrew the two USB-input bolts and take it out. This will have to be done because it covers part of the touchscreen loop.

9. Then work only with gloves so as not to leave fingerprints on the phone display. Otherwise, they will have to be wiped off for a long time with cotton swabs. We pry (just like when disassembling the case) with a sharp object (best of all with a blade) the edge of the touchscreen, we draw the blade along the entire perimeter. We lead along the very edge so as not to scratch the plane of the phone screen. The touchscreen is glued to the body with adhesive tape.

10. Insert a new one in place of the cracked touchscreen, after removing the protective film from the adhesive base. Putting it together in the reverse order, remembering to connect all the loops. The work is done, it remains to think about what to spend the saved money on.

Korean manufacturers produce high-quality appliances, including washing machines.

Usually, if a company is engaged in the production of various household appliances, and not just one kind of it, it is considered that the product is rather mediocre. This cannot be said about the Samsung brand.

A diversified product is in great demand among buyers, regardless of whether it is a household appliance or a telephone.

The company maintains its image by giving all its strength and knowledge to production. But, like any manufacturer, high-quality Samsung equipment also breaks down. We can not always turn to repairs: then there is no money, then there is time.

In order not to spend money on the restoration of the unit in the service center, it is best to perform the simplest operations to restore the equipment yourself.Today we will tell you how to repair a Samsung washing machine with your own hands.

Most often, heating elements, filler valves deteriorate in washers, drive belts are damaged.

1. Open the back cover of the device.
2. The belt must be pulled with one hand midway between the pulley and the motor to pull it out. Take a Phillips screwdriver, insert it into the groove of the pulley, and support the belt with your other hand.
3. Slide the screwdriver over the groove, freeing up any large portions of the belt and pulling it out of the groove.
4. When the belt has been removed, carefully inspect it from all sides for scuffs, damage. If any, replace it with a new one.
5. Now you need to put it on the pulley. Place the inside of the strap against the groove. To make the drive belt finally secure in place and get dressed quickly, turn the pulley with your other hand a little.

The pump consists of several parts:

1. electric motor;
2. shaft;
3. impellers (impeller);
4. a snail to which a branch pipe and a drain hose are connected.

Signs of a pump breakdown:

• The laundry is not rinsed or rinsing does not work at all.
• The car stops.
• Spin does not start.
• The water is not drained or drained for a very long time.
• Washing powder is not completely washed off with water when it is collected, but remains in a small amount in the cuvette.

First of all, you need to determine whether the pump was the cause of the breakdown of the washing machine or not.

Listen to the pump. If it hums, makes noise, trying to turn on, water does not fill up or does not make any sounds, this means that the pump is broken.

Do-it-yourself Samsung washing machine pump repair is carried out in the following order:

• unscrew the drain filter and clean it. The pump impeller may be jammed due to debris;
• if, after cleaning the filter, you have not achieved a positive result, water has neither been poured nor poured into the device, then there may be a blockage in the drain hose. Dismantle it and rinse it. Then put it back and run the test wash. If the pump continues to work incorrectly, look for the malfunction further;
• unscrew the filter and look into the holes, shining a flashlight. Feel the pump impeller with your fingers and try to twist it. If it rotates with difficulty, then feel for the debris that interferes with it: threads, hair and remove them;
• if the pump impeller rotates freely, then disassemble the washing machine further to check the pump malfunction. The pump does not work correctly, mainly due to its blockage.

Therefore, the drain pump and the pipe must be thoroughly flushed. But to get rid of the blockage, you need to remove them.

To do this, you need to perform the following operations:

1. remove the container;
2. put the typewriter on its side;
3. unscrew the bottom protection;
4. remove the drain pump and pipe. Place a well-absorbent cloth under the pump, because when you take it off, some water will pour out;
5. disconnect the clamp to release the branch pipe;
6. disconnect the plug from the drain pump sensor;
7. to remove the pump, loosen the clamp and unscrew the fasteners.
8. remove the drain pump, turn on the hot water tap and place the hose under it so that the debris is flushed out of the hose and makes a passage for water;
9. fix the bottom;
10. put the washing machine back and check if it works.

The reasons for pump failure can be different. Do-it-yourself repair of the drain pump of the Samsung washing machine depends on the causes of the breakdown.

• If it's not a blockage, disassemble the pump: unscrew the snail. At the same time, take a picture of how the electric motor is connected to it, so that you can then assemble it correctly. If the cause of the breakdown lies in the casing, which has been deformed by hot water, and the impeller blades touch it, then cut each blade by 1 mm with a knife, not more. Otherwise, the power of the washing machine will be much lower.
• The impeller can also be the cause of pump breakdown. It can simply jump off the axis: it hums, but does not pump water. In this case, the impeller must be replaced.
• Review all rubber gaskets.If any of them is cracked, rubbed, torn, then replace it.
• Sometimes the pulley fails. It can also be replaced.

The inlet valve becomes unusable much less often, but such cases are mainly due to the fact that the sealing gum loses its ability to retain water, because it crumbles and cracks. We need to replace it.

Open the top cover of the washing machine. The barrel-shaped element connected to the filler hose is the filler valve.

Loosen the clamp, disconnect the sensor wire, unscrew the filler valve. Look for cracks in the rubber gaskets. If they are torn, replace them with new ones.

Use a multimeter to check the resistance of the sensor wire. If everything is in order, put the part back.
