"It's not hard to check for faults. Starting with its function and the components on the circuit board, you can get a general idea of its circuit composition. Looking at the layout of the components, we found the module for signal feedback amplification.

The component arrangement of the signal feedback amplification part is very special, and you can see that the electrical circuit above is composed of a triode amplification circuit. In this part, the only thing that can produce that kind of fault phenomenon is the 0.13 mm coil. ”

Lin Fuzhi, Daddy Lin, was stunned when he heard it. Lin Yan's analysis was meticulous, and it was simply a one-hit hit.

Without looking at the circuit diagram, you can understand the structure of the electrical appliance at a glance. This is a legendary skill, and it is a dream skill for all electrical repairers. What's more, this bastard boy also said the cause of the failure at all.

I also discovered this fault, but I measured it with an instrument, part by part. This is a difference from the level of failure that can be seen at a glance.

When Daddy Lin thought of this, his thoughts suddenly opened up. He thought of something, and he asked cautiously, "You also repaired that TV that day?" ”

Originally, Daddy Lin thought that the TV was damp, so it was broken. Send it to the store and open the shell, the wind blows, the moisture is gone, and it will be fine.

However, the more he thought about it during the two days he was hospitalized, the more wrong it became. Because, Brother Jingyuan said. This machine has not been repaired in several repair shops before, why come to yourself, just blow the wind blows. There must be something strange about this.

Thinking about today's projector, the spearhead of all these clues is directed at his own bastard, so it must be right to ask him.

If that TV was also repaired by him, then his own son would be too terrible. Although the TV is common, it does not mean that it is simple in structure.

Imagine how complex it is to transform an invisible or intangible electrical signal into a living, clearly visible moving image.

Even a layman watching soap operas in front of the TV every day can't imagine how the TV works.

"Hey......" Lin Yan sighed, just because of his subconscious words, he caused so many things. The good sleep time is used to popularize science for the father who is a "professional repairer".

Lin Yan said slowly and weakly, "The problem with that machine is relatively big. I came back from school that day to see you after the repairs. There is some doubt that the resistance value of a resistor has changed because of the passage of time.

I was skeptical, but I wasn't sure. So when you went to the other room, I scribbled the resistor with a pencil through the shell that I thought was problematic.

I think you also know that the material of the pencil lead is not lead, but graphite, which can conduct electricity. As long as you control the application force, you can increase the conductivity of the resistor at will.

I estimated the deviation of this resistance and applied the right amount of graphite. I didn't know if it was repaired at the time.

However, judging by your later conversation with Uncle Jingyuan, it seems that it has been repaired. ”

"It's really ......fixed," Father Lin muttered to himself in distraction. He also knew why his son looked at him at the dinner table that day, with a smile on his face. It turned out that he didn't take a fancy to my private money, but laughed at my skills.

The back waves of the Yangtze River push the front waves, am I really old......

Although Daddy Lin's technology in repairing electrical appliances has always been up for debate, his self-confidence has always been very strong. It's just that now his self-confidence seems to be crumbling.

Due to the level of soundproofing of this house, it really needs to be strengthened. So Mother Lin, who was lying in the bedroom upstairs, was woken up and heard the conversation between her husband and son.

Although, she couldn't understand what the two were saying. However, although she didn't know it, she was still happy for her son, who seemed to have made something wrong.

No matter how hard the old man is, he is the owner of an electrical repair shop. A housewife, in addition to expecting her husband's career to progress, also hopes that her children will be successful.

"Daddy, can I go?" Lin Yan missed his bed, and he wanted to go back and press on it.

"Good boy, worthy of my son. You will definitely become a great appliance repairman in the future. Lin Fuzhi patted his son on the shoulder.

In the small theater in my head, the drama of my glorious retirement, Lin Yan's son inheriting his father's business, and his grandson inheriting it was played. At that time, my own repair shop will also be a century-old shop with a name resounding throughout Akihabara.

"I'll try, then I'll go first." Lin Yan prevaricated. I turned around and wanted to go back upstairs to sleep. He didn't want to be some glorious electrical repairman.

His ambition was simple, to make more money easily before the age of eighteen. Retire at the age of 20 at the latest, and then live a half-world-long retirement life.

Enjoy life, nothing more than that.

"You go to sleep." Daddy Lin knew that Lin Yan would have to go to school tomorrow. Therefore, it didn't get mixed up to the point where he stayed up late to repair electrical appliances with him.

After a while, he still hadn't recovered from his excitement. I don't know if he would faint with excitement if he knew that his son had made an unprecedented game arcade machine.

When you are in a good mood, you are more productive.

Daddy Lin hummed a tune of unknown meaning in his mouth and repaired one electrical appliance after another.

Finally, he sat on a stool with his arms propped up on the workbench. I was stunned at the computer with the side cover lifted and the motherboard blackened.

Although he was in a daze, Daddy Lin didn't dare to start again. Because, he was afraid that he would be electrocuted again, or that he would not be able to repair this machine himself.

Therefore, he did not realize that the heart of the computer, the core processor, has been missing.

If you don't let my son see it tomorrow, I don't know when he will become so powerful, but he may be able to fix the computer.

Daddy Lin thought about it, he turned off the light and went upstairs to sleep.

Lin Yan woke up early the next morning, pushed open the window, and the cool air blew into the room. After the rain, the outside seems to have been washed away from all the dust and has become much fresher.

Mom is back, too. No more eating slices of bread that were baked by a bread machine. Ready for a real breakfast.

I went to school. Lin Yan picked up his schoolbag and walked out of the house.

No matter how well the road is repaired, after a long period of wind and sun, and cars run over, there will inevitably be some potholes.

Lin Yan carefully avoided these puddles, so as not to stain his shoes. In his careful colleagues, he saw groups of elementary school students, happily stepping into the puddle.

There was a "bang" and a circle of water droplets were splashed.

This is the life I yearn for, Lin Yan thought to the rising sun.
