管座,是彩电中故障率较高的部件之一,管座受潮漏电后,容易引起电视机图像模糊,光栅暗淡,显像时间过长的故障。有的漏电严重的故障机,经过几十分钟甚至几个小时,图像还不能清晰,为排除故障,防止故障面扩大,这时应及时更换显像管管座。但有的机型、管座与显像管脚配合过度紧密,难以拔下,特别是粗管劲配9脚管座的(如福日系列机),由于管脚多,配合紧
Headers, is one of the components of higher failure rate in color TV sets. When the headers are damp and leaky, the TV images are easily blurred, the grating is dim, and the imaging time is too long. Some serious fault leakage machine, after dozens of minutes or even hours, the image is not clear, in order to troubleshoot, prevent the fault surface to expand, this time should be replaced CRT seat. However, some models, the tube seat and the imaging pin with the over-close, it is difficult to unplug, especially the thick tube with 9-pin tube seat (such as the Fuji series machine), due to the pin more, with tight
