Back in the 1990s, she became rich through scientific research

Qin Hongfei started to dismantle the machine, and in a few seconds she dismantled it until only the frame was left. The store was surrounded by many people watching the show, but this did not affect her performance at all.

If anyone who knows her strength is here...

It will definitely be called overkill!

Qin Hongfei has never mastered the basics of repairing electrical appliances, but she knows the principles of these things better than anyone else. As long as she understands the principles, there is nothing that cannot be repaired, so the approximate level of difficulty is - the level of stacking blocks in kindergarten. .

The reason why the TV cannot be turned on is because of the relationship between the power supply and the motherboard. Qin Hongfei repaired the power supply and the motherboard one by one through troubleshooting methods...

The boss looked more and more confident that she couldn't fix it. How could she fix it without replacing the parts?

Someone nearby saw it and asked, "Aren't you going to replace the parts?"

Qin Hongfei said that logically it should be replaced, "But the parts are expensive! It hurts money." TVs are so expensive at this time, more than 2,000 per unit, and replacing the motherboard and power supply would cost hundreds.

This willful answer leaves people speechless and choked.

However, the next development made them somewhat unbelievable.

Qin Hongfei didn't know how to do it on the power supply and motherboard. She even used a hair dryer and electric welding. The process only took half an hour. Then she installed it back and started plugging in the power. The TV that originally couldn't start started up. , although it is just a snowflake.

"Yeah, is it fixed?"

"It's not even close, the voice is also bad." Qin Hongfei said, and then continued.

"How is this possible?!" The boss looked at the lit TV in disbelief. No, it would definitely break after a while.

However, this moment has passed another fifteen minutes.

Not only did the TV not go dark, but the sound of rustling snowflakes also began to come out. Qin Hongfei took the sky formation and started tinkering with the channel closing. Soon, the picture gradually appeared. Although it was very blurry, it might be activated. If it can close the channel, it was indeed It was repaired. "Guest, you can move your TV away. Welcome to come back next time."

The young man's eyes widened, "This is impossible..." He had obviously gone to several stores and it was true that the TV was so bad that it couldn't be repaired and could only replace parts. What, how... "You did something to it. What?"

Qin Hongfei naturally knew why he was so shocked, but she didn't point it out. She just smiled and said, "I am a repairman, so I will repair it naturally. If you are in doubt, you can test it now. We will not provide any after-sales service outside our store."

When the young man heard this, he naturally stepped forward and slapped her hard twice. You are black. You have a black screen.

Unfortunately, it didn't go as he wished.

In full view of everyone, he wanted to get some water or something, but this little shabby shop didn't even have stools, let alone tea to serve people.

Qin Hongfei looked at him with a half-smile but not a smile, "The main power supply of the TV is inside the machine, and the casing has a certain protection against external forces. If you hit it like this, there is no way to break it. Now that we have determined that there is no problem, Then go back with it." She accepted the money.

The young man knew that he might be in trouble this time, but he couldn't regret what was written in black and white in front of so many people, so he could only hug his TV and leave with blood dripping. Before leaving, he glanced at the neighbor next door fiercely. The owner of the store said, "Trash."

He vowed that he couldn't fix it, which made him more confident. But what's the result?

The boss suppressed his blushes. Soon, he thought of something and smiled strangely, "Xiao Qin, my uncle underestimated you. If you are not good at this skill, you will start to learn to do tricks, right?" ?”
