It depends on how your phone is, if the phone does not exceed 1000 when you buy it, then don't repair it, and you can't keep up with it after a year. Because if it is not used for one year, it can be guaranteed for free.

What phone? If there is no warranty or man-made damage, it will cost 3 or 400 yuan to replace the board, and if the mobile phone is under 1,000 yuan, it has been used for a year or two, and there is no need to repair it.

It can be recovered, when the motherboard is damaged and the mobile phone is repaired, the original information can be read, but if the memory chip is also damaged, the original stored information can only be recovered with particularly professional equipment and programs.

Now the memory chip of the mobile phone is integrated on the motherboard, and the SD card will definitely be removed by itself before repair, and the integrated storage may also be replaced when changing the motherboard, so you must remember to explain it when repairing it to avoid information loss.

There are three main parts on the motherboard of the mobile phone:1. a baseband part.

Baseband chip and power management chip: responsible for coding.

2. Radio frequency part.

RF processor and RF power amplifier: responsible for sending signals out and receiving signals.

3. Other parts.

CPU memory for various controllers (touchscreen, Bluetooth, WiFi, sensors, etc.). There are also microphones, earpieces, speakers, cameras, interfaces for display screens, etc., all of which are soldered to a circuit board, and the whole board is called a mobile phone motherboard.

Can be fixed. However, most of the mobile phone repair points are to replace the motherboard, and those who can repair the motherboard are professional masters.

When I went to repair the phone, I said that the motherboard was broken for the following reasons:

Because the motherboard is relatively high, the repair of the motherboard of the mobile phone may be equivalent to more than 30% of the original price of the mobile phone, in addition to the motherboard has no technical content, a faulty mobile phone, if you need to check in detail, it may take a long time, or the maintenance master does not have the technology to repair, so changing the motherboard saves money and trouble.

Related information: If only some components of the mobile phone motherboard are loose or damaged, the probability of repair is very large, if the mobile phone motherboard burns out the entire circuit due to water or power surge, the probability of repairing the mobile phone motherboard is very low.

Hello, I am happy to serve you and give you the following answer: Lenovo mobile phone motherboard is broken and must be repaired. Depending on the model, the repair cost will also vary.

Clean the phone case and install it properly. In the repair process of a broken motherboard of a Lenovo mobile phone, you should master relevant knowledge, such as the inspection, replacement and installation of mobile phone parts, and how to use relevant tools correctly to avoid unexpected situations.

1. It can be repaired, but it is worth repairing it by yourself, and if you use the mobile phone for a few years, there is no point in repairing.

2. Symptoms of broken mobile phone motherboard: There are many aspects of broken motherboard, specifically to see what kind of machine it is, and what symptoms appear when using it; The worst performance is, of course, that it can't be turned on, there are many parts on the motherboard, and different parts have different functions, such as CPU, memory, power supply IC, power amplifier IC, etc.; The most important thing is, of course, the CPU, if it is bad, it may not turn on.

Summary. If the motherboard of the mobile phone is broken, whether it can be repaired depends on the degree of damage If the motherboard of the mobile phone is only loose or damaged by some components, the probability of repair is very large. For example, if a cable on the motherboard is broken or the camera is damaged, it can be repaired by replacing the cable or camera component.

If the mobile phone motherboard is only partially loose or damaged, the probability of repair is not large. For example, if a cable on the motherboard is broken or the camera is damaged, it can be repaired by replacing the cable or camera component.

If the entire circuit burns out due to water or power surges, the chances of the motherboard being repaired are very low. Even if it can be repaired by chain transportation, the repair cost is still very large, so in this case, it is generally recommended to directly replace the motherboard in the whole shed after sales.

If only some components of the mobile phone motherboard are loose or damaged, the probability of repair is very large. For example, if a cable on the motherboard is broken or the camera is damaged, it can be repaired by replacing the cable or camera component such as a cavity. If the entire circuit burns out due to water ingress or power surge, the chances of the motherboard being repaired are very low.

Even if it can be repaired, the cost of this repair is still very large, so in this case, it is generally recommended to replace the entire motherboard directly. If the mobile phone motherboard is damaged, the data may be rescued Some children's shoes cannot read the data in the mobile phone because the mobile phone motherboard is damaged (such as work documents, WeChat chat notes, photos**, etc.), in this case, you can go to the after-sales point to confirm whether the flash memory chip on the motherboard is damaged, if it is intact, you can solder the flash memory chip to the new motherboard to obtain the original data. However, not all mobile phone repair points provide this service, so you need to ask about the service before processing.
