Sony's products in this period are of excellent quality, and circuit boards generally do not have problems.

This is a mechanical failure, and the principle is actually quite simple.

Li Yunhai removed the front panel and then disassembled the rear panel.

He inspected the motor and the speed-stabilizing circuit to see if the buck resistor pole had burned out.

Finally, he carefully removed the circuit board and removed the spring blade of the micro switch.

This spring has been deformed and cannot come into contact with the microswitch.

Li Yunhai carefully hammered the spring blade and put it back on.

He first installed the circuit board, and then fixed the front and rear panels.

Before putting on the screws, I turned on the machine and tried it.

The music, which was as clear as flowing water, came out of the stereo.

The scene was cheered: "It's repaired!" ”

Someone muttered, "That's too easy, isn't it?" Just like that, I made 20 yuan! That's more than half a month's salary for my dad! I think 2 bucks is enough for him! ”

Li Yunhai said without raising his head: "Classmate, repairing is only worth 2 yuan, but if you know how to repair it, this knowledge point is worth 20 yuan!" Knowledge is power! Knowledge is wealth, do you understand? ”

Teacher Jiang smiled: "Okay, you're right! You've got what it takes! You deserve it! ”

Li Yunhai smiled, looked up, and just glanced at the dancing girl.

The girl smiled at him, her eyes bent into crescent moons, and there were two shallow pear vortices at the corners of her mouth.

I saw that she was about 1.7 meters tall, tall and beautiful, wearing a silk dance skirt, showing a plump good figure, her face was like a hibiscus, her eyebrows were like willow leaves, her eyes were more charming than peach blossoms, her skin was like snow, and her black hair was pulled into a tall beauty bun, like a budding peony flower, beautiful but not demonic, glamorous but not vulgar, charming and charming, and fascinating.

The young teacher clapped his hands: "Okay, students, hurry up and prepare, the performance will start on time at seven o'clock." ”

The onlookers dispersed.

Li Yunhai installed the screws, tried the machine again, and made sure that there was no problem, so Shi Shiran left.

Li Yunhai, who originally only had five yuan, earned 20 yuan by chance!

That's a lot of money for him.

His family is rural, his parents and parents, facing the loess and turning their backs to the sky, digging and eating in the soil, in recent years, the responsibility of the field, after the land is contracted to the household, the family conditions are slightly better, but the life is also tight, and the family has no money to spare.

Li Yunhai went to secondary school for three years, he was frugal, and finally saved ten yuan of pocket money for himself, went to visit the Shen family, and he generously bought a gift of almost five yuan, which was the most money he spent in his life.

And the 20 yuan just now is also the largest amount of money he has ever earned in his life.

He did not leave, but sat in the auditorium to watch the free show.

In this era when watching open-air movies is considered a luxury, literary and entertainment life is already lacking, and high-level theatrical performances like this are even more difficult to find.

The graduation performance of the art school, the program is wonderful, especially the dance, the girl on the stage, the dancing posture is light, the body is as light as a swallow, the body is soft as a cloud, the arms are soft as boneless, and the dance posture is like a lotus, such as the butterfly flying among the flowers, such as the gurgling water, such as the bright moon in the deep mountains, such as the morning light in the alley, such as the round dew on the tip of the lotus leaf, so that people are like drinking wine, drunk and unable to restrain themselves.

After watching the performance, Li Yunhai left the art school and returned to his school to rest.

Early the next morning, Li Yunhai woke up.

He was in no hurry to return to his hometown.

The adventure of making money last night made Li Yunhai realize that this was a good opportunity to make money.

In this era, there is a shortage of technicians!

In particular, some special machines cannot find special maintenance personnel in society.

Li Yunhai has dealt with electrical appliances and machinery all his life in his previous life, and has accumulated a lot of rich maintenance experience, whether it is old-fashioned or new-style electrical appliances and machinery, in his hands, he only needs to know at a glance where the problem is and how to fix it.

After a night of thinking, Li Yunhai decided to stay in the provincial capital for a while to earn some money before going home.

He was afraid that his family would be worried, so he wrote a letter and mailed it back, telling his family that he was doing something at school and would not go home for the time being.

Li Yunhai had breakfast in the cafeteria, bought a few big steamed buns to take with him, put a set of repair tools that he had worked hard to accumulate in the past few years, and put them in his yellow canvas schoolbag with the steamed buns, and walked out of the school gate.

After studying in the provincial capital for three years, Li Yunhai wandered around when he had time, and he had long been familiar with all the scenic spots and streets in the provincial capital. Especially the train station, Xinhua bookstore, book market, and parks, he will go to take a walk every Monday when he has time.

It was not easy for him to jump out of the farm, wasn't it just to see the wonderful world outside? Even if you can't go all over the world, you have to walk thousands of miles in the provincial capital.

Li Yunhai came to Wuyiwen near Wuyi Square.

The full name of "Wuyi Wen" is Wuyi Stationery Store, and its predecessor was a state-run stationery store. Opened in April 1980, the business scope is very wide, there are high, medium and low grades. Later, it was renamed "May Day Stationery Mall".

It is a six-storey building, the lower two floors of which are the shopping mall, the third floor is rented out to several different commercial establishments, and the upper floors are presumably the dormitories and staff clubs of the mall employees.

Li Yunhai had come here to buy stationery before, and knew that there were printers and photocopiers for sale here.

He found a green tree near the Wuyi Wen Company, sat down on the edge of the flower bed under the tree, and took out a piece of corrugated paper that had been prepared long ago from his bag, with a line of large characters written on it:

"Professional maintenance of typewriters, printers, photocopiers at a fair price."

Li Yunhai put the corrugated paper on the root of the big tree, this is the advertisement he played. Then he pulled out a novel and leaned against the trunk of a tree to read.

He's just waiting for the rabbit.

There are not many places in the provincial capital where you can buy these equipment, except for Wuyi Wen, that is, Kewen, the popular computer city and printer city in later generations have not yet been built!

Wuyi company operating stationery and modern office equipment, as many as 10 series, more than 8,000 varieties, computer equipment, photocopying equipment, musical instruments and other commodities in the province of the market share of more than 40%, is the country's largest stationery professional shopping mall.

People who come to Wuyiwen Store must have potential customers of Li Yunhai.

This is the most prosperous section of the provincial capital, with a lot of traffic and people coming and going.

Passers-by occasionally glance curiously at Li Yunhai lying under the tree.

A morning passed, and Li Yunhai did not open.

He brought steamed buns and water, and didn't go to a restaurant at noon, but nibbled on two steamed buns and drank a few sips of water for lunch.

July is on fire, and the sun is in full bloom.

Fortunately, it is very cool under the shade of this tree, and there are high-rise buildings next to it to block the poisonous sun, and the past few miles of Wuyi Square is the riverside, and the river breeze blows over, which is cool and pleasant.

There was still no business in the afternoon.

He's been here for a day's long wait.

But he brought the novel, and he finished reading half of it.

The next day, Li Yunhai still brought steamed buns and repair tools and came to Wuyiwen to wait for business to come to the door.

At eleven o'clock in the morning, a middle-aged woman with curly hair came to Li Yunhai.

The woman looked at the words on the corrugated paper, looked at Li Yunhai again, and asked, "Little comrade, is your master here?" Will you fix a typewriter? ”

When Li Yunhai heard this, he immediately came to his senses, put down the novel in his hand, and said with a smile: "Sister, the master is here!" Do you want to fix a typewriter? ”

The woman looked around and said, "Yes! There is something wrong with the typewriter in our unit, where is your master? ”

Li Yunhai patted his chest and said, "I am the master!" ”

The woman sighed and shook her head: "What are you kidding?" Little comrade, will you fix a typewriter? No one believes you when you say it! ”

Li Yunhai said eloquently: "Eldest sister, let me tell you this, looking at the entire provincial capital, no one knows typewriters, printers and photocopiers better than me." If I can't fix it, others can't fix it well. If someone else repairs it well, my price is cheaper than theirs! Moreover, let me tell you, eldest sister, as long as I have repaired the machine, and the same problem occurs in the future, I will give you a free warranty within a month! ”

The woman sighed, took a step back, and looked Li Yunhai up and down: "You little comrade, how old are you?" It's not a small tone! ”

Li Yunhai said with a smile: "Eldest sister, I am a graduate of Xizhou Industrial Technology School, and I studied the major of repairing electrical appliances and machines!" Am I more reliable than those so-called teachers who haven't been to school for a few days? You have to believe in the country's education level! ”

The woman said, "Are you a secondary school graduate?" Don't have a job? ”

Li Yunhai said: "I haven't just graduated, and it's not time to report yet, I'm idle at home, using what I learned after graduation, coming out to find something to do, solving the practical difficulties in the work and life of the people, and helping to solve the economic difficulties of the family by the way." ”

The woman snorted and said, "You little comrade, you talk quite interestingly. ”

Li Yunhai took out his graduation certificate and work registration card, and handed it to the woman: "Sister, I really don't lie to you, this is my certificate, you can check it." ”

The woman took the graduation certificate, looked at the steel seal on it, and said, "What a secondary school student!" Have you ever seen a typewriter? ”

Li Yunhai didn't intend to show off his talents, he just wanted to gain the trust of the other party, and said: "Old-fashioned mechanical typewriter, right? Chinese or Western? Chinese is equivalent to a movable type printing board, which is actually similar to the principle of steel plate printing, printing wax paper, you can make copies. ”

The woman sighed, "You really know about the typewriter!" I told people that they didn't even understand what it was! Okay, you come with me to the unit and see if you can fix it. ”

Li Yunhai put his things in his bag and followed the woman.

The woman works at a bank on Wuyi Road, not far from Wuyiwen, and it takes more than ten minutes to walk.

"I saw you when I passed by there yesterday, but I didn't dare to call you when I saw that you were too young." The woman laughed, "There is something wrong with the typewriter in our unit, and no one will fix this." ”

Li Yunhai said: "Computer printers and photocopiers are popular now. There are not many people who understand this kind of old-fashioned machine. What is wrong with your typewriter? ”

"Come in and see!" The woman led Li Yunhai to an office in the back.

It turned out that when the bank used a typewriter to print materials, it found that the typed content was not neat.

The woman took out a few pieces of printed wax paper and handed them to Li Yunhai to see: "Oh, that's it, the printed materials are all like this, and they can't be used at all!" ”

Li Yunhai didn't need to disassemble the machine, he glanced at the printed materials, and saw that the words on it were crooked, so he knew what the problem was.

"Sister, I just told you that the typewriter I repaired has after-sales service. In other words, I fixed this problem, and if the same problem occurs within a month, you find me, and I will fix it for you for free. ”

The woman said, "Okay, you say, how much will it cost to fix it?" ”

Li Yunhai thought to himself, this bank is a rich man! If you don't knock on their bamboo poles, you won't be able to get over it on your conscience!

So, he decided to quote a very high price for repairs.

"Eldest sister, I'll help you fix it, 80 yuan!"

The woman said, "Can you really fix it?" ”

Li Yunhai saw that she did not bargain, but repeatedly asked if it could be repaired, and knew that his offer was acceptable to the other party.

"Eldest sister, you can rest assured, I'll fix it for you."

Li Yunhai's idea is correct, in this era, it is indeed not easy to find professional maintenance personnel.

Occasionally find a knowledgeable master, and the price is much higher than Li Yunhai!

A typewriter costs a few thousand yuan, and it only takes a few dozen yuan to repair it, which is relatively not expensive.

This is a relatively old-fashioned mechanical typewriter, extremely expensive, only available in government agencies, and most people print with steel plates, as well as with ink.

The woman pointed to the typewriter and said, "Okay, 80 bucks!" You fix it, I'll pour you a glass of water to drink. ”

Li Yunhai got her consent, so he put his yellow cloth schoolbag on the desk, took out his tools, and began to repair the typewriter.

This failure couldn't be simpler, simpler than the problem we had last night!

The typing is not neat because the positioning bell of the typewriter is malfunctioning.

All you need to do is adjust the positioning bell, and the whole process takes less than three seconds.

The woman brought a glass of water, put it beside Li Yunhai, and said, "Little comrade, drink saliva and repair again." ”

Li Yunhai had already adjusted the positioning bell and said to the woman: "Eldest sister, I have already repaired it, you can try the typewriter again." ”

The woman looked at him in surprise: "Have you repaired it?" ”

Li Yunhai picked up the water cup, drank it all in one gulp, and said with a smile: "Yes, eldest sister, I have already repaired it." As I said, this machine has the same fault, and I will repair it within a month! So, you don't care how much time it took me to fix it, and you don't have to ask me what method I used. ”

There were other people in the office.

A middle-aged man who was a little bald said: "Director Wu, I did see what parts he repaired, and it was done in a few seconds!" ”

The woman was Director Wu, and she sighed: "I didn't see it, little comrade, you are really a master!" ”

As she spoke, she took the wax paper used for printing and turned on the machine to try to type a piece of paper.

This time, the printed material is clearly handwritten and neat.

Director Wu smiled happily: "Hey, it's really good!" Little comrade, you have excellent skills! To tell you the truth, we invited two masters who repaired electrical appliances, and they tinkered for a long time, but they still didn't fix it! ”

Li Yunhai said with a smile: "There is a specialization in the art industry. The master who repairs electrical appliances usually repairs TVs and radios is OK. As for this mechanical typewriter, I guess they haven't even seen it! How do you know how to repair it? ”

Director Wu said: "Little comrade, thank you for your hard work!" You've helped us a lot! I've got to type a copy today! ”

Li Yunhai said with a smile: "There is money to make, but it is not hard." ”

Several people in the office burst out laughing.

Director Wu immediately took out 80 yuan and handed it to Li Yunhai.

In a few seconds, Li Yunhai earned 80 yuan!

Add to that the 20 dollars he earned the night before, and he has a huge sum of 100 dollars in his pocket!

In this era when the average salary per capita was 40 yuan, it only took him two or three days to earn two or three months of other people's wages.

This feeling of making money is as exciting as hugging Shen Xiulan that day!

And that's just the beginning.
