  Chen Ziping originally only planned to briefly introduce Lin Hong to the content of the arcade machine, but he didn't expect that Lin Hong seemed to be very familiar with circuits and would ask a question at critical moments, gradually opening up his conversation. It just so happened that this arcade machine was a bit difficult to repair, and for a while, he couldn't detect where the fault was, so he detected it while introducing the relevant structure and general principles to Lin Hong.

  This time, Lin Hong came into contact with the concept of processor and memory. On the card board, there was a row of circuit components, which were graphic and command storage and processors. As for the specific principles of these two structures, Chen Zhiping did not elaborate, nor did he himself understand much, only knowing their general functions. The memory, as its name suggests, is used to store data. The processor, on the other hand, is used to process input signals and convert digital signals from the graphic memory into analog signals output to the scan board, which are then displayed on the CRT.

  Chen Ziping simply took it as a review and reorganization of the knowledge he had previously grasped, as for whether Lin Hong could understand it, he clearly did not hold any hope, after all, this knowledge, let alone a primary school student, even in college, it would take some time to understand, because there was no such knowledge to learn in college.

  Lin Hong's eyes lit up as soon as he heard it, and in an instant, he had built the entire model of the arcade machine, just like it really existed in his mind.

  "What's wrong with it?" Chen Zhiping was getting anxious, he had checked all possible places, but still couldn't find any clues. Generally speaking, if the screen is pitch black and has no raster after booting up, just like there's no power supply, usually it's a problem with either the power supply or the CRT.

  However, Chen Zeping carefully checked these two parts and all parameters showed that they were extremely normal.

  Just as Chen Ziping was losing his patience and thinking of putting the machine aside for now to deal with later, Lin Hong suddenly said:

  "Little brother-in-law, it should be a problem with the scanning part."

  Chen Ziping was slightly stunned, then shook his head: "It shouldn't be. I just checked with a multimeter, and also disassembled zd801, d806, r802 for testing, all of which were fine."

  "Electrolytic capacitor C806." Lin Hong said he had no choice but to report a more specific component name.

  Chen Ziping only then realized and reflected on it, his face full of surprise as he looked at Lin Hong: "Lin Hong, have you come into contact with these things before?"

  What Lin Hong just said, ordinary people generally do not know about it, and even technical personnel can't touch it. Even if his elder brother opened a repair shop, the rural maintenance personnel are generally only at the stage of replacing parts, that is, first determine which part is broken, and then replace the entire part as a whole.

  It is said that "a master's skill can be seen in one move", and Lin Hong's two sentences just now have shown his extraordinary attainments in this aspect.

  "I just know some technical aspects of TV." Lin Hong didn't say much, this sentence was enough. He figured out that eighty percent of the malfunctioning parts of this game console were in the display section.

  Chen Ziping seemed to see Lin Hong for the first time, carefully sizing him up before re-examining the electrolytic capacitor that Lin Hong had just mentioned. Electrolytic capacitors are a special type of capacitor with very large capacitance, usually tens or even hundreds of times larger than ordinary capacitors. C806 is a model number of an electrolytic capacitor, where the letters and numbers represent specific parameters.

  There were dozens or even hundreds of capacitors of various sizes on the circuit board, each with its own function. Lin Hong accurately stated the capacitor model number, so Chen Ziping quickly found this electrolytic capacitor named C806.

  Chen Ziping placed his hand on the electrolytic capacitor and felt it for a moment, discovering that this capacitor was obviously much hotter than other components. He looked at Lin Hong in surprise, although he hadn't used an instrument to detect it, but in his heart, he had already acknowledged what Lin Hong said.

  Then he replaced this capacitor with an electric welder and used a multimeter to test it. As expected, the capacitor had severe leakage.

  Chen Zeping left for a while, and he couldn't find the electrolytic capacitor of this model temporarily. So he found a scrapped machine in the warehouse, removed an electrolytic capacitor from the circuit board, and then returned to the game room to solder it onto the game console.

  He pressed the power button and the screen lit up instantly, already fixed.

  At this moment, it is already known that the problem lies in this capacitor. In this way, tracing back, one would naturally think that this fault is not a big deal and can be thought of with careful consideration. However, Chen Zhiping does not think so. Maintenance is like this, reverse deduction is easy, but thinking from the phenomenon to locate the faulty component, this process is fraught with difficulties.

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

  "Uh, elementary school fifth grade."

  Chen Zeping suddenly felt that he could no longer continue to ask questions, a fifth-grade elementary school student and electronic master stood in front of him, whose level was likely even more formidable than his own, giving him an extremely defeated feeling.

  Chen Zeping is very clear about the current education level, and naturally will not think that all children are now so fierce, can only say that Lin Hong this kid is too abnormal.

  "Unexpectedly, Xiao Pang's vision is quite good. Either he doesn't find any friends at all, or when he does, he finds someone as awesome as this." Chen Ziping thought to himself.

  Actually, although they are all from Dongling City, they have been developing in the southern coastal cities before, and only started to slowly shift their focus back to their hometown in the past two years. Xiaopang just transferred back this semester, due to the differences in education level and economic development between the two places, resulting in Xiaopang being unable to get along well with his schoolmates, as he put it, they have no common language.

  "Lin Hong, you're really amazing. I believe that in the future, you will definitely become a leader in this field. Work hard on your studies, and after getting into university, you'll be able to learn even more profound knowledge." Chen Ziping said.

  "Thanks for the encouragement, Little Brother-in-law!" Lin Hong nodded and then plucked up the courage to ask, "Little Brother-in-law, have you ever seen a real computer?"

  After asking, Lin Hong waited expectantly for Chen Ziping's reply.

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

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