After the power dropped, the spokes were unreadable. Traditionally, everything is all about it:) The autopsy shows the decomposition of the two elements on the controller, circled in a square. After studying the history of the problem, I realized that the problem cannot be solved by simply replacing the controller. You need to repair the native chip or re-soldering the flash memory chip to the same chip. Controller model. Ask local maintenance personnel for help. Geographically Moscow.
I have to highlight it with a 1 pixel green line. If so, this is a very subtle hint.
Without this clue, I would not find it.
They have been oxidized and even covered by the smoke above. If there is something serious, 31 will be burned out.
Most likely, you only need to replace the fuse to replace the input suppressor.
Seagate was placed for 5 years and plugged in two power sources at the same time. How to do it.
I clicked the mouse every now and then, and then I started to use it only for seeds. I checked everything if there was a problem. Once, the computer started to load it for a long time. After half an hour it turned on and it seemed to have nothing. The same happened, I checked if there was a problem, again the rules. Copy from it and start the movie. After a while, when you try to open it, it hangs for a long time, and it loads after restarting until you pull it out and put it on the shelf. After restarting, the screw made a clicking sound, nothing more, the screw was not visible. Check the contact between the receiving area and the control board: where the contacts of the head block are connected, they may be oxidized. Therefore, this kind of optical disc will become blunt without a head (including head flapping). I have encountered this situation myself, especially at the old Seagate company. In this case, an eraser is sufficient. Usually, the panel needs to be loosened with screws, which can be easily unscrewed, but with very little effort. The most important thing is not to disassemble. ) Without loosening the circuit board, check its diagnostic contact pad: if there is a bare oxide pad, you can roughly understand the contents of the back. In addition, you can try to stupidly nail the screws with the model name, but this is always at your own risk. Also, check out the rest of the properties: if some values are increasing, there is no harm in searching. Use an eraser-you will see the specification as it should be. On the back, is the same platform used for the main unit contact feet. Of course, this is just the fastest way to try to fix this problem, and of course, as mentioned above, even if no power is used. Its price is too high, but I still don't understand what it is. Can you tell me?
It seems that some CDs can be ignored. : Reference: Therefore, don’t pay attention to 1 and newer and 2.5-inch drives, other models and all attributes on the and drives, non-zero values indicate problems, for example, with bearings, etc.
Although it is not, it looks more like a burned out resistor.
I have the same things, the same disks and the same failures. During maintenance, they don't even want to try to re-soldering. Maybe only the power is interrupted, or it will reach the memory. Then only 3100 will help. Write: / _ or email: mail.
I renamed it to avoid infection. Finally, I came across an interesting circuit board, so you can submit this post:) This defect is a typical failure of this series of circuit boards and adjacent lines (with similar power systems). When the design engineer decides not to cool the power transistors, the circuit board problems begin. A polygon with a through hole on the other side? No, you haven't heard.
Let's try to remove them, considering that they are soldered to copper, which can be very difficult. It turns out that the board has been in the hands of the craftsman, but after 3 days of repair, the scope of the problem is getting bigger and bigger: the lower shoulders are fresh, the upper limbs are burned out, and the controller flies to the rainbow. It is not surprising if the new transistor is soldered to the old burned substrate. After calling the adjacent transistors, we found that they were also slightly punctured and some freezes, so we deleted them.
After the operation, we will start repairing the burned area. First, clean up, remove all the roasted copper, and use a scalpel and some mother to remove the plate mask.
Next is the routine, we repair the copper, solder, press, return a pair of resistors and install new transistors. 
The anti-ultraviolet mask makes our intervention more invisible.
On this note, the recovery of the frying part and my post are over, the board is still waiting for the controller from. For this, I ask for leave until the next article! Well, due to telepathy, since I have not completed the psychic course, I cannot accurately determine all faults. (They started school from the second semester)) After a while, the phone called me.
This happens because the phone has too much parsing. The plume of smoke broke just where it connected the glass to the plume. Under these protective covers, there are important roads to -, part of the audio codec track and the main 1.8 line, on which all important microcircuits are located. This is a paper jam between the rails. This must be resolved.
Naturally, I will not send anything, but switch to the web version. First, you need to check its maintainability.
All data will be lost, and repair costs will double. First, you need to order a serial address so that the phone can be activated on the server. At the beginning of April, the cost became 21 dollars, the waiting time started from 11 days, how much the fucking cost. I was rejected and confirmed to order again within a month. Unable to cancel the order, here either wait to refuse to receive, or wait until you receive the serial number by mail. To activate successfully, all you need is a serial phone number and a Bluetooth and-address.
I called me and got information that my finger must be valid. Over the past few days, I discovered that starting from 14, the original button serial number must be written into the memory. But even with him, there is nothing I can do. The scanner disappears with the memory, and the system has no failure error when the power is turned on. The system sees it, but refuses to activate it. This remains to be seen. On this basis, the repair may have been completed, and 6501 enters the auditorium again) Now I am already working hard to add a second physical card to it, and I think I will write a small post soon. ) ... Various old iron pieces will be restored soon, but considering the wishes of the previous article, today I want to introduce the most authentic ones. Attention, there are many pictures! Therefore, I got the repair from, which was given to me by a friend 5 years ago when he wanted to demolish the garage. For me, she is not particularly interested, because her condition is very bad, and for toys, I have another attachment. But while waiting for the necessary prerequisites for another project, I decided to do something with this poor guy. The cartridge eject lever does not work, only one joystick completes. Generally speaking, sadness is trouble.
In this case, another console panel is placed. There are 3 connectors on the front of the development board. This case is designed for non-removable joysticks and there is an expansion port on the front. In addition, for non-native boards, the acquisition button and the power button are connected separately. As far as I know, the previous owner didn't want to disturb the transfer buttons and joysticks at all, but saw off the front part of the plank from the old plank. 
I am particularly satisfied with removing the power stabilizer from the board. How and why is a mystery.
It is not clear whether the problem is in the toggle switch or in the non-contact of the stabilizer.
We can do the same for platforms where the pop-up lever is unnecessary. Film photoresist, printing template on film, UV irradiation and soda ash development.
I am not a bad painter, so the quality of factory painting is impossible. Of course, it can be done better-it is a matter of practice and skills, which is still developing =) A complete video of the process. For new subscribers, I will be very happy because we still have a lot of ideas about content. Thank you for your attention, your
There is a problem that when the module fails, the device becomes dangerous-why? The problem lies in the activation system. When the device is updated or refreshed from the beginning, it needs to be activated. To this end, the following methods are used:-Address-Bluetooth address--A unique number is formed by these parameters. With the help of these servers, they can provide activation certificates. If some of these operations do not work in the phone, the phone will turn into a pumpkin. They brought the equipment, but did not update it.
In fact, this means that the microcircuit is faulty or the soldering between the microcircuit and the circuit board is poor. After a detailed inspection, it was found that the device had been repaired by Uncle Liao's uncle and stuck to his nephew’s tears. Now it is necessary to solve the problem, Solution 2:-Roll the microcircuit to restore it-if there is a fault, replace the microcircuit. The fault may be that some components in the microcircuit are burned out. I just said that something in the microcircuit burned out, but isn't it her own? Yes. This is actually not a microcircuit, but a system on a chip filled with resin. For this photo, thanks to the people in the profile forum. There are big pitfalls when replacing microcircuits. The module is bound to-flash memory. Therefore, you will need to remove the memory and modules. I took off the motherboard, which is strange, the memory is already soldered. Interestingly, directly under the back of the board is. This is the cause of the failure. When replacing the memory, it will warm up slightly, the soldering will break, and it will stop working. This is the problem.
Normally, it happens slowly, but due to local overheating, the process speeds up.
The problem has been resolved and another unit has been restored. Why did I start this position with such an educational program? I do not know. For example, it is difficult for me to explain to a person why I need to charge for this. Nevertheless, I have to reconnect the flash drive, because when I dry the hair dryer on the board from the back, the flash drive falls off. All the fun of 5.5 is always stainless steel. Everything becomes so simple and complicated at the same time. I am happy to advise young professionals and those who need urgent welding assistance. ) Communication: Thank you for your time and patience. All people are healthy, don't get sick!
Or why sometimes a penny spare parts are expensive. Yes, he tightened everything tightly, and even had to pull the socks out of the closet and put them on immediately to avoid interference.
After swimming in the pool after vacation, I got my phone. From the demonstration, it was learned that the mobile phones were less than 4 months old, one of them arrived at me a few months after the purchase, and the second one was with the owner for less than a month. He decided to check the moisture protection at work. I will tell him to fix it. The official warranty is naturally cancelled because: moisture and dust have entered your dust and water protection device, which is not covered by the warranty. Diagnosis starts from 1501. So, what if you flood a hundred lawn mowers? 
Basically, dozens of water passes through the top of the face (marked in green). It, or more precisely point sensors and proximity sensors, die immediately and very frequently, with no possibility of recovery. In this case, the point is dead, and in another position, the proximity sensor is dead. As you know, they remain unchanged and are bound to the processor by the serial number of the face. Just like the buttons on the old version. The most frequently asked question by subscribers and customers: I flooded my phone, how much money should I carry? I will also answer here: The drowning device is a lottery (not a TV, but a normal device, no ), so lucky. The maintenance cost can be the price of diagnosis, or the impossibility or inconvenience of maintenance. This model expired a week after the flood. Stosh, a few drops of water have arrived.
The microcircuit is an additional stabilizer for the main audio codec, and is in a short-circuit state like an adjacent small capacitor. This is the main power cord and the phone cannot be turned on. How did these oxides occur, or just flooding? this is very simple. For example, moisture will only scatter from the board onto the battery (in this case, water droplets will accumulate on the protective screen of the main camera). There is no danger nearby. This is the saddest thing. Under the action of the heat emitted by the work phone, this drop of water evaporates and the steam enters the phone. He cannot go out alone without help or blows, because the phone will be sealed when it gets wet. Even if the phone is turned off, the main power cord is always 4.3 volts. As you know, electricity attracts water, and water flows along the simplest path-this is the first power line available. The condensate gradually accumulates on a continuously charged capacitor and gradually starts to pass small currents through itself (in working conditions, it filters out the ripple of the microcircuit). Once the air conditioner is covered with a conductive layer, it breaks and starts to make all current flow through itself, while becoming more green and attracting water. At this time, the phone will immediately shut down. The protection system of the battery and the main controller does not allow the mobile phone to ignite from the peak current output, but only cuts off the power. The same situation. Why is the entire power cord not immediately oxidized? But because the current there began to leak and it would attract water vapor. As they said, people with slippers and people walking on tiles) battery current output can reach 31. You can watch the exploding electronic white fish on. But this was carried out under the condition that all protective measures failed. In the above, a protection device can provide insurance to the brother, that is, another current protection device. This is a little theory and a little practice. Since no more damage was found anywhere, I will perform visible processing and search in the process. This is the power cord in the picture. After inspecting each microcircuit, I did not find anything suspicious (in a uniform square, I marked the area to be repaired.
I soldered the top of the circuit board into place, assembled it into the case, and then poke it into the charger. Recently, I saw this phone and changed its display. Has been working for nearly 2 years. Therefore, not all flooded phones are beyond reach. ) In fact, this simple repair method is to remove the capacitor, causing the customer to lose seven thousand. The second phone is more expensive because the flash driver is full of water, so I had to buy a donor to remove the necessary microcircuits. The speaker and proximity sensor circuits were also affected. He also replaced it. Why is such a simple repair worth so much money? At that time, the original cost of the monitor used was about 30,000 U.S. dollars (flew into the monitor at the risk of breaking). The equipment used to disassemble each model of motherboard and consumables was their own. On average, In other words, for 8 or more models, the dismantling cost is $8001. Well, the rest is time/rental/spare parts, because I can)) You can ask a question in my #. Here, you can also monitor repair photos that are not shown here. Don't get sick)) See you! Or why some phones take a long time to repair. In fact, this phone has not been completely repaired, and spare parts for only a penny cannot be purchased anywhere. But I will start again.
Okay, well, it doesn't matter to me, it's mainly the background, so there are some starting points. and so. What if you want to heat your phone in a microwave oven? The first step is to burn all the antennas in the phone.
Since I will purchase the bottom plate separately and remove some components from the original exploding board (on the Chinese board, half of the hooks are missing, so the network signal is weak, and problems such as charging may occur), so I will start with-the network.
Here comes the first problem-I cannot find the same microcircuit. All the donors are tired, no one. The main difficulty in repairing Sony phones is that there are no solutions. Not at all. You must do everything in a similar way to other phones (all phones have the same design principles).
There is no antenna nearby, but on the back of the burnout. So the emissions burned that road and flew here. I replaced the burned out microcircuit, added a damaged resistor, and further improved the antenna.
This means it does not work elsewhere. Then I will figure out how to-find the right microcircuit. I am starting to use a cellular network.
This completes the repair and waits for the appearance of spare parts. Now, we need to restore the antenna on the plastic box. I did not check every range. But I think everything is fine here, because there is no call between switches. Still need to deal with-the antenna on the plastic. The principle is the same. I solder the conductors for spraying, nothing more. Recently, I was digging again. , It is impossible, many roads in the middle layer have been burned (I tore off half of the plank to find its heading and direction, even cut some unnecessary roads, but repaired them) . Only-valid. Everything else runs seamlessly. All these wires are signal wires, which makes it complicated to find the trace and the cause of the problem, that is, they are directly grounded to the total mass of the phone, and when they ring, they will ring on any capacitor on the board . Usually only a cellular network has been raised for several months. -It is working, but due to the lack of duplexer microcircuit, it can capture distances within 11 cm, and I am still looking for it. That's it. Why me. There is no need to check the phone with a microwave oven, which will not bring benefits. It is good that the battery does not explode, otherwise the phone will become 111% of the dead. ) Is it recommended to restore the phone after the microwave oven has heated up? This question can only be answered after inspection, because in this case, all antennas are burned out, and in another case, the processor may be short-circuited. However, if the price of the phone is less than $5,000, then the convenience of repairs will be immediately questioned, because such repairs (such as mail services) require an average of 4000 repairs. If you are interested, I can equip my workshop at home as soon as possible, and then burn a cheap phone that is half working (flash flash memory) and try to repair it. I will also try to complete all work suspended due to the situation as soon as possible, and conduct activities remotely through delivery. : A seminar has been organized. I work remotely. Since it is a course booker, we will proceed first. Nothing happened, even if the screw was not detected. Without wasting time, let us look for a donor screw. Oh, I found out that even though the revisions are the same, there are only 321 gigs instead of 251 (536287 revision.
