Heavy humidity, abnormal TV failure in autumn
Yesterday, the reporter visited a number of home appliance repair organizations in the city, found that the recent changes in the types of appliance repairs, from the summer main air conditioning repair to the current TV and other home appliance repair.
"In all kinds of home appliances, TV sets often have faults, but they do not affect the use, so most families will make do with them." The person in charge of a home appliance repair organization in the city introduced that TV images and sounds sometimes do not exist, or Some channels are unclear, there is always a bright spot in the middle of the screen when the computer is turned off, and these conditions may cause the picture tube to burn out.
The reporter learned that most TV sets are partially or completely damaged and cannot work properly. It is not because the components exceed the service life, but because the users are not properly used and carefully maintained. Therefore, once the TV is different, it is best to find a professional in time and find out the reason. In addition, you should also pay attention to the following points when using the TV: TV should be away from humid environment, strong magnetic substances, smoke and dust, various harmful gases, chemical solvents, and avoid direct sunlight.
Ask
What other appliances are prone to problems in the fall?
With the gradual decline in temperature, what other household appliances are prone to problems in the fall? Mr. Zhang, the head of Yangzhou Weixiaobao appliance repair company, said that from the current daily repair orders, the summer air conditioning maintenance peak has come to an end, but with As the temperature dropped, the number of maintenance in the water heater increased.
“Now the most used urban residents are gas water heaters.†Mr. Zhang told reporters that due to the long-term use and not cleaned up in time, the scale inside the gas water heaters gradually increased, which will greatly affect the “heating†of small-displacement water heaters. In addition, Mr. Zhang reminded the general public that the weather is getting colder, the frequency of water heaters is increasing sharply, and the water heater spontaneously ignites into a fire, so it is best to abandon the old water heater. Mr. Zhang pointed out that the self-ignition water heaters have a longer life span. On the one hand, such water heater parts are aging and there are endless hidden dangers; on the other hand, due to the limitations of the times, some machines have technical innate deficiencies. Although the water heater sales instructions indicate that the water heater needs to be tested once a year, in fact many users do not have the habit of regularly maintaining the water heater.
remind
Avoid getting wet, home appliances should always be "opened"
So how do you avoid the “strike†of home appliances in the fall?
"The TV set will not be seen for a long time, and the failure rate will be greatly improved." After the sale, the staff of Huiyin Household Appliances admitted that the air humidity in the city is high. If the appliance is not used for a long time, the moisture in the air will cause the interior of the TV. The electric oil inside the air conditioner is solidified, which in turn causes the circuit board to burn out, and the life of the appliance is greatly shortened.
The appliance salesperson reminded that as the season changes, an effective way to avoid the damp of home appliances is to open the appliance frequently. If the TV is turned on, it will heat up, and the moisture will be emitted and absorbed. “In the fall, even if some appliances are not used, they should be used occasionally for a while, which is also a way to extend the life of appliances.â€
