有的人看完电视关机后,总要过一段时间再罩机,认为这样有利于电视机冷却,可以更好地保护电视机。其实,这是一种误解。电视机关机后,热空气开始冷却收缩,居室内的灰尘也随着冷气被吸入机内,这样久而久之,尘埃就会损坏机内的零、部件,从而直接影响电视机的使用寿命。自然界绝大多数昆虫也和人体一样是导体,有一定的导电能力。如把电视机摆在蟑螂等虫子时常出没的地方,一旦它从机壳后的散热孔爬进机壳内,就有可能造成短路。因此,关机后应立即上罩。另外,不论是彩色或黑白电视机,除早期生产的部分31厘米黑白电视机或印有快速显像字样的进口电视机外,在收看节目完毕后均不必拔下电源插头。这是因为关闭电视机开关后,机内电源开关已把外界电源完全断开,频繁插拔电源插头,反而容易造成电源线断折损坏。(沈平)
After some people watched the TV off, it would take a while before the re-capping machine, that this is conducive to the cooling of the TV, you can better protect the TV. actually it is a kind of misunderstand. After the TV is turned off, the hot air begins to cool and shrink. The dust in the room is also sucked into the air conditioner as the air conditioner is turned on. In the course of time, the dust will damage the parts and components in the machine and thus directly affect the service life of the TV. The vast majority of insects in nature and the human body is the same conductor, a certain degree of conductivity. If the TV set cockroaches and other insects frequented place, once it climbed into the chassis from the cooling holes, it may cause a short circuit. Therefore, the shutdown immediately after the cover. In addition, no matter the color or black-and-white TV, apart from the early production of some 31 cm black-and-white TV or imported fast-displayed imported TV sets, do not have to unplug the power plug after watching the program. This is because after turning off the TV switch, the power switch inside the machine has completely disconnected from the external power supply, plug the power plug frequently, but likely to cause damage to the power cord breakage.
