They say it's too easy to fix the tv now
Some maintenance technicians, however, collect money when they come to the door and look at the tv and say the main plate is broken. If you change the main board, it's 700, 800
The price of individual maintenance techniques may be higher, but it takes time for technicians to come in, eat themselves and have children in their homes to attend school. Now that their time has taken, the money is certain, and that's not bad. If you think they're expensive, you can get a cheap mechanic to fix it, and you can do it yourself

I. Benefits of self-maintenance
1. Saving money
Unless it is a very small electronic product, most televisions, washing machines, refrigerators, air conditioning master boards can be found on the internet. Since these parts come from second-hand power recycling or from shredded television, they are not expensive, ranging from dozens to over $100。
Logical panel
For normal television maintenance, which is expensive, it is not the cost of spare parts, and it is normal to charge 300 or 400 for maintenance of the above-mentioned doors, saves money and is very expensive to repair。
2. Not killed
It is true that individual maintenance staff would be too expensive to see that you are not familiar with and that you are not capable of doing anything. If you're not familiar, you don't know how to behave, you're the only one who gets killed。

3. A sense of achievement
Most men like to fix a toy for their sons, change their own faucets, fix a lamp, but it's a lot of success when the problem is solved. If we can fix the tv at home, she'll spoil you again。

4. Exercise ability
The mechanics, the washing machine, the air conditioner and the apprentice also come around day by day, and we are afraid to tear down the machine, to do it, mostly by strangers who are not familiar with it. Each maintenance exercise exercises its ability to do things. More machines are repaired and any machine is repaired。

Ii. Risk of self-maintenance
1. Machine scrap for newer
We look online at the maintenance video, the maintenance video of the washing machine, and the maintenance video of the air conditioner, which makes us look like it's really very simple to repair the television and washing machine. It's too easy for me to do it myself. In fact, the initials are for amateurs and for introductory people, because many of these videos present the most basic, simple operation, and the most critical and central part is passing. You won't know until the lord says so. Even if the lord said so, you wouldn't remember. When you have a problem, you will remember that it is the most crucial step to draw attention to。
I saw some of my classmates on the internet telling me that they were working on the tv, with their ears on both sides of the screen, trying to take it off, and then the ears fell off and the screen broke. It's not familiar with the working principles of the lcd screen。
2. Accidental electroshock injuries
Both televisions, refrigerators and air conditioners are used to turn off the power, which means that the main or power panels of these appliances are hot, that is, hot marked on the board, which is absolutely untouchable. Any touch at the hot end will put you down。
There is also a need to be aware of the treatment of large-capacitated discharges when power is maintained. Because of the different design lines, some of the power switches are not discharged to the large capacitor, and this 300v voltage can last 10 days or even a month, as long as they touch both ends of the capacitor。
Three, more tools in your hands
Different appliances, fixed screws, and different modes of installation, require different maintenance work. For a long time, there will be pliers, electric drills, electric screws, screwdrivers. If you're a hottie, fix a neighbor or something, you can open a maintenance store with your hands on it。
Iii. How to select suitable panels
While we know that the television is broken, it will take some time to find an identical panel. Because the main panel of the television sets divides the hardware version and the software version, although the hardware is identical and the interface is the same, the suitable screen is different, and it cannot be installed, and it can be painted。
1. Same interface
Whether we change the main board of the notebook or the main panel of the television, the peripheral interface has to be identical, or the functional line is redundant, leading to a loss of functionality, which is that the machine has not been repaired。
In particular, televisions, internal screens, power, buttons, horns and infrared interfaces must be identical when replacing the main panel. Different interfaces are difficult to modify, rather than changing them。
The external interface would need to be identical, otherwise it would not match the location on the television shell, even if it could not be installed。
Two, screwdriver
Stabilizing the main plate would be convenient if the screwhole were consistent, with at least two or three screws required. Because the main panel of the television is fixed at the back of a lamp in the metal shell, the screw lock is flushed. If they are not matched, these sprouted screw holes may lead to short-circuiting of the main panel to work。
Three. Same main plate number
Whether it is a power plate, a main board or a logic board, it has a hardware plate number. What we need to note is that this plate number is not the only one that matches a model, and maybe a plate plate that matches a variety of models, which may be the case, although most of the main plate is the same, some of the functional interfaces are different. So when we pick out the board, we need to look at not only the shape, but also the details。
4. Same or higher software
Like tv master boards, logboards, notebook master boards, tablet main boards, which are internal to run systems and software, the hardware that is supported on the outer edges has problems matching, so we also need to consider software versions, usually high-end, low-end versions。
The five-screen model is the same
While televisions are of similar sizes on the screen, as are screen interfaces and even logical panels, the matching master plate, because of its built-in screen drive, can only be found if the software is not replaced。
In a simple sentence, if the main panel is selected, it needs to look at the model, and it needs to look at the main panel, and it needs to look more at the screen model, which is the same。
