The TV at home suddenly "strikes", what is going on?

Recently, many residents in Yangzhou have encountered problems with their TVs. For example, Miss Shi's TV started making a "beep" sound with a faint ozone smell when turned on. Initially, she didn't think much of it, but later discovered that the TV had no image despite having sound. This TV was purchased last year when she and her husband moved into their new apartment in the Southern District. However, since they usually live with their parents, the TV in their new home has rarely been used. Similarly, Mr. Hu's family also experienced a similar issue. His TV screen remained blank for several minutes before showing any image. Now, it takes over an hour for the TV to display an image after being turned on. Mr. Hu mentioned that during the summer, his family stayed at his grandmother's house, leaving the TV unused. He hadn't expected that returning home would result in such a malfunction. According to local appliance repair professionals, the high humidity in the fall contributes significantly to these issues. Many households in Yangzhou have reported problems with their TVs, ranging from no sound to complete black screens. These malfunctions are often caused by prolonged disuse or improper storage of the devices, leading to potential short circuits within the appliances. A senior technician at a major repair shop explained that even minor issues like unclear images or occasional static can eventually damage the TV’s internal components. Proper maintenance and regular usage are crucial to prevent such failures. Additionally, it is recommended to keep TVs away from damp environments, strong magnetic fields, and direct sunlight to prolong their lifespan. As temperatures drop, other household appliances like water heaters also face increased risks. Mr. Zhang, head of a local appliance repair service, noted that with fewer people using air conditioners, more customers are turning to water heater repairs. He emphasized that regular cleaning of water heaters is essential to prevent scaling, which can hinder heating efficiency, especially in smaller models. Furthermore, older water heaters pose significant safety hazards due to worn-out parts and outdated technology. It is advisable to replace such units to avoid accidents. To maintain the longevity of your appliances during the fall, it’s important to occasionally power them on, even if they aren’t being actively used. Doing so helps evaporate accumulated moisture and prevents internal damage. For instance, simply turning on the TV for a brief period can help dry out its components and reduce the likelihood of future breakdowns. Overall, staying vigilant about appliance care and understanding seasonal maintenance requirements can save both money and hassle. Regular checks and timely repairs are key to ensuring that your household electronics remain functional throughout the changing seasons.
