1.注意地磁的影响。大屏幕彩电的荧光屏应朝南或朝北放置,使地球的磁场方向与显像管内电子束射线方向一致,防止地磁影响色纯度。当然也要远离带磁性材料的录音机、磁疗器等设备。2.注意透气、散热。大屏幕彩电应放在干燥通风处,远离暖气等热源,离墙壁至少要10-20cm,也不要放置在通风不佳的电视柜内 1. Note the effect of geomagnetism. The screen of the large-screen color TV should be placed facing south or north, so that the direction of the earth’s magnetic field is consistent with the direction of the electron beam in the picture tube to prevent the influence of the magnetic field on the color purity. Of course, you should also stay away from devices such as tape recorders and magnetic therapy devices that use magnetic materials. 2. Pay attention to ventilation and heat dissipation. The large-screen color TV should be placed in a dry and ventilated place, away from heat sources such as heating, at least 10-20cm from the wall, and not placed in a TV cabinet with poor ventilation
