With the continuous development of television, we have seen tremendous changes in the TV industry. Although television technology is becoming more and more advanced, we cannot forget the tragedy that happened in TV before. The following Wanwei home grid editor will introduce the user to the TV series how to prevent explosions and prevent natural 3 common sense, don't miss it!
First, what kind of TV more prone to spontaneous combustion or explosion?
1. TV sets that have exceeded their useful life
Relevant experts suggest that the current life of the TV set is 8 years, and the safety factor will continue to decrease as the life of the home TV is approaching. If the user does not pay attention to maintenance, this "overaged" TV set is prone to accidents such as spontaneous combustion or explosion.
2, modified TV
It is understood that 95% of modified TV sets are assembled with old picture tubes and new circuit boards, and even if the circuit board is new, it is often used to change the circuit board of the small screen TV to the large screen TV. Therefore, such television sets have a short life span and are a safety hazard.
Second, what is the cause of spontaneous combustion or explosion of the TV set?
Some experts pointed out that there are two reasons for the self-ignition or explosion of TV sets. For example, after the TV is powered on, the electronic components in the machine will generate a certain amount of heat, which is radiated through the cooling holes of the TV casing. If the TV is placed In a TV cabinet that is not conducive to heat dissipation or a place that is not ventilated, heat will accumulate in the machine, causing damage to electronic components and smoke.
In addition, there are also reasons for external influences, such as the screen being hit or struck by lightning. TV antennas erected outdoors, if lightning protection devices are not installed, it is easy to introduce lightning into the TV set during thunderstorms, resulting in extremely high temperatures, which will not only cause the TV to catch fire, but also may cause the picture tube to explode, seriously endangering personal safety.
Third, how to prevent TV accidents
1. Purchase products that have been certified and produced by large formal enterprises. Some private small enterprises produce relatively unprotected products.
2. Pay attention to whether the TV environment is safe. Do not place the TV near a heat source or in a humid environment to keep the air dry.
3. Don't watch TV with a fault. When the TV shows odor, smoke, grating abnormality, there is a fire or fire in the machine, it should be shut down immediately and sent to the professional maintenance department for repair. When replacing critical originals with safety signs, you must use original, factory-approved, reliable, and secure originals.
4. Use and maintain the TV correctly. When not in use, power off and unplug the plug instead of using remote standby. Turn off the TV in the event of a strong thunderstorm, and unplug the power cord and cable. For those who do not have cable TV, be sure to choose to stay away from the power supply line when setting up the outdoor antenna, especially away from the high voltage line.
Do not cover the dust cover immediately after watching the TV. Because the TV set will generate a lot of heat when it is turned on, once it is turned off, it will cover the dust cover, which will block the heat dissipation inside the TV. TV opportunities have a negative impact, it is best to cover the dust cover after about 20 minutes of shutdown.
