Today, I found a shadow to the right on the LCD screen. I checked the settings of the monitor and restored the initial settings.

 

No way, you can only seek help from Baidu. The results are all strange, but one thing is the same, that is, they have not solved the problem.

 

Someone said on the Internet that there may be something like a Speaker next to it. Without a speaker around the monitor, I tried to move the monitor a few times. the problem still exists, and the screen turns yellow several times. In one move, the screen is black... show no signal... I immediately checked whether the lines behind the monitor were normally connected, and checked whether the connections between the cables and the chassis were normal. As a result, I found some looseness. After being tightened, the screen was no longer black and no yellow screen was displayed, no shadow. Solve the problem!

 

I remember that the same was true when I was repairing a computer for a friend. The computer had no sound, and the result was a redo of the system, and a variety of drivers on the Internet. Finally, I decided to dismount the host and confirm whether the onboard sound card had a problem. Then I suddenly found that the sound output interface of the speaker had an error!

 

A while ago, we had a similar unforgettable memory on our website. A function has some disagreements with the text description, which leads to errors in user understanding and usage, attracting a lot of complaints. These complaints directly led the developer to check the code several times, flip the error log several times, and test the code multiple times on the website. It takes a lot of time. The modified text description will generate an unexpected one!

 

To solve the problem with a devout attitude, what is a devout attitude? Believe in our software and hardware, and believe that we are more likely to make mistakes than software and hardware. If you have any problems, start with yourself and find your own problems. Are you using the instructions? Are you planning violations? Software and Hardware have more or less bugs and exceptions, but there are fewer problems than errors in use.

 

Of course, as a software and hardware developer, in addition to ensuring the product quality as much as possible, it is necessary to avoid errors that may occur during user use. Proper guidance and prompt are necessary. For example, food guide on instant noodle packaging, deletion tips in windows, and identification of men and women's toilets. Although we cannot guarantee that the male/female restroom is "available" (with paper and location), it is better than "completely unavailable" brought by the wrong restroom.
