On some festivals, many families or shopping malls will hang a string of colorful lanterns to set off the atmosphere. But after repeated use several times, you will find that these colored lights are not on. What should we do in this situation? Then let's take a look at the solution that colored lights are not lit in series.

First, the reason why the colored lights are not lit in series

First of all, we need to know why the colored lights are not lit in series. Therefore, when the lantern is not on, we first need to check whether there is a problem with the power supply of the lantern. We can connect the power of the lantern first and then see if the indicator light is on. If the indicator light is on, it means that the power supply of the lantern is good, but there is a problem inside the lantern. If the indicator light is not on, there may be a problem with the power supply of the lamp.

Second, how to repair the series lights that don't work?

When we check, if there is something wrong with the power supply of the lantern, we need to see if the plug and socket of the lantern are loose. If it is loose, press the plug hard. If there is something wrong with the household circuit at home, resulting in the series connection of colored lights is not bright, then it is necessary to find a professional to check and repair. If the lanterns are not installed properly, the whole power supply should be turned off, and then the lanterns should be reinstalled one by one in series.

And if there is something wrong with the quality of lanterns, we need to replace them in series, just replace the lanterns with problems. If most lanterns have problems, there is basically no need for maintenance. It is more worry-free to make a string of new colored lights directly.

The above is the reason and maintenance method of colored lights in series shared by Bian Xiao, hoping to help friends who are confused. You know, solving the problem is not the first step. The first step is to find the cause of the problem and then deal with it according to the cause. Blind attempts will not only lead to bigger problems, but also waste time. Therefore, when friends solve problems, they must learn to find the reasons first.
