故障现象:偶尔出现满幅回扫亮线。图象极淡薄,但伴音正常。此故障有时连续工作数小时不出现。有时一开机就出现。或开机十分钟后才出现故障。检修过程:根据伴音正常,有满幅回扫亮线,一般是视放一级故障。当开机故障再现时测量视放管集电极电压,当表笔一触印刷线路板时,故障随即消失。用手摸视放级各元件的温度正常,仔细检查亦无
Symptoms: Occasionally appear fullback flyback bright line. Very thin image, but the sound is normal. This failure sometimes does not appear for several hours of continuous operation. Sometimes a boot appears. Or boot 10 minutes before failure. Maintenance process: According to the normal sound, a full swing line, generally put a failure. When the reproduction of the boot failure measured as the collector tube collector voltage, when the table pen touches the printed circuit board, the fault disappears. Touch the temperature of the various elements of the normal level of grading, no double check
