1 图像抖动电视机使用一段时间后,有时会出现图像抖动现象.当更换新显像管后,图像抖动也就消失了.这说明显像管高压导电通路上接触不良.在高压接通时,图像发亮;高压断开时,图像消失.人眼就会感觉到图像有一明一暗的抖动现象.
1 image jitter After a period of time, the image jitter sometimes appears. When the new picture tube is replaced, the image jitter disappears, which indicates poor contact on the high-voltage conduction path of the picture tube. When the high voltage is on, the image is bright. When the high voltage is disconnected, the image disappears, and the human eye can feel the image has a bright and dark jitter.
