Chapter 46 An acquaintance will know if there is any

Chen Ziping only intended to briefly introduce the content of the arcade to Lin Hong, but he did not expect that Lin Hong seemed to know the circuit very well. From time to time, he asked a question at critical moments and gradually opened his chat box. It happened that it was a little difficult to maintain this arcade machine, and he could not detect the fault for a while, so he introduced the corresponding structure and general principle to Lin Hong while detecting it.

This time, Lin Hong came into contact with the concept of processor and memory. There is a row of circuit components on the card board, which are graphics and command memory and processors respectively. As for the specific principles of these two structures, Chen Ziping did not elaborate. He did not know much about it himself. He only knew the general function. As the name implies, the memory is used to store data. The processor is used to process the input signal, and convert the digital signal in the graphics memory into an analog signal to output to the scanning board, and then display it in the picture tube.

Chen Ziping regarded himself as re-reviewing and sorting out the knowledge he had mastered before. As for whether Lin Hong can understand it, he obviously does not have any hope. After all, this knowledge, not to mention a primary school student, can't understand it for a while even in college, because there is no knowledge in college. .

Lin Hong's eyes were shining, and he established the whole model of the arcade in an instant, as if such an arcade really existed in his mind.

"What the hell is wrong?" Chen Ziping became a little anxious. He checked all possible places, but he still had no clue. Generally speaking, after booting like this, the screen is dark and there is no grating, just like not plugging in the power supply. Usually, the power supply part or the imaging tube part fails.

But Chen Ziping carefully checked these two parts, but the parameters showed that they were very normal.

Just when Chen Ziping lost his patience and wanted to put this machine on first and then deal with it later, Lin Hong suddenly said:

"Little uncle, it should be a problem with the line scanning part."

Chen Ziping was slightly stunned, and then shook his head: "It shouldn't be. I just checked it with a multimeter, and ZD801, D806 and R802 have also been removed and tested, and there is no problem.

"Electrolysis C806." Lin Hong said that he had to report a more specific component name.

At this time, Chen Ziping realized that he reflected. He looked at Lin Hong with a surprised face: "Lin Hong, have you been exposed to these things before?"

What Lin Hong just said, in general, ordinary people don't know at all, and ordinary people with average technology can't reach it at all. Even if his cousin is a maintenance shop, and the maintenance personnel in the countryside generally only stay in the stage of replacing parts, that is, first determine which place is broken, and then the whole The whole part has been replaced.

As the saying goes, "A connocist will know if there is any", the two words that Lin Hong just said reflect that his achievements in this regard are very extraordinary.

"I just know some technology about television." Lin Hong didn't say much. It's enough to have this sentence. He saw that 80% of the failure of the game console was in the display part.

Chen Ziping seemed to see Lin Hong for the first time. After carefully looking at him, he began to check the electrolytic capacitor just mentioned by Lin Hong. Electrolytic capacitor is a special capacitor with a very large capacity, usually dozens or even hundreds of times larger than ordinary capacitors. C806 is a type of electrolytic capacitor, and letters and numbers represent certain specific parameters.

There are dozens or hundreds of capacitors on the circuit board, all of which have different functions, but Lin Hong accurately said the capacitor model, so Chen Ziping quickly found this electrolytic capacitor called C806.

Chen Ziping put his hand on this electrolytic capacitor and felt it, and found that the temperature of this capacitor was obviously much higher than that of other components. He looked at Lin Hong in surprise. Although he had not yet used the instrument to test, he had already recognized Lin Hong's statement in his heart.

Then, he replaced the capacitor with electric welding, and then tested it with a multimeter. Sure enough, the capacitor has seriously leaked.

Chen Ziping left for a while, and he could not find the electrolysis of this model for the time being, so he found a scrapped machine in the warehouse and disassembled such a piece of electrolysis from the circuit board. Then go back to the game hall and weld this electrolysis to the game console.

He pressed the power button, and the display suddenly lit up, which had been repaired.

At this moment, I know that the problem is with this capacitor. If you push it back, you will naturally feel that this fault is not a big deal. If you think about it carefully, you can also think of it. However, Chen Ziping doesn't think so. Maintenance is like this. It's easy to reverse, but there are various difficulties in the process of locating faulty components from the phenomenon.

"Lin Hong, are you still in primary school now?" Chen Ziping asked.

"Well, the fifth grade of primary school."

Chen Ziping suddenly felt that he could not continue to ask questions. An electronic master in the fifth grade of primary school stood in front of him, and his level was probably better than himself, which gave him a feeling of failure in life.

Chen Ziping is very clear about the current level of education. Naturally, he will not think that today's children are so powerful. It can only be said that Lin Hong is too perverted.

"I didn't expect Xiao Pang's vision to be good, or he didn't look for a friend, and he found such a good one as soon as he looked for him." Chen Ziping thought so in his heart.

In fact, although they are all from Dongling City, they have been developing in southern coastal cities before, and it was only in the past two years that they began to slowly shift their focus to their hometowns. Xiaopang only transferred back from other places this semester. Due to the gap between the education level of the two places and all aspects of economic development, Xiaopang has been unable to get along well with his school classmates. In Xiaopang's words, he has no common language with them.

"Lin Hong, you are really good. I believe you will definitely become a leader in this field in the future. Study hard. Only after you are admitted to college can you learn more profound knowledge." Chen Ziping said.

"Thank you for your encouragement!" Lin Hong nodded, and then summoned up the courage to ask, "Ouncle, have you ever seen a real computer?"

After asking, Lin Hong waited for Chen Ziping's answer with an expectant face.

"Of course I've seen it." Chen Ziping smiled and then said, "Not only have I seen it, but I also have one myself."

"Really?!" Lin Hong felt that his heart was about to jump out.
