本刊2004年6期任丽萍同志提到彩电“慢显像”原因除管座受潮外,还与电源的滤波电容漏电及开关电源正反馈电容开始未被激活有关,这的确不假,但是笔者碰到的几例彩电“慢显像”却既不是显像管座漏电,也不是电容漏电或未被激活,请看下面实例。例1一台福日 HFC2168彩电,开机时有伴音无图像,约2min(分钟)后才慢慢显示很暗的模糊图像,随着时间延长,亮度增高,图像逐渐清晰,开始也换过管座,结果故障依旧。在刚开机后查二视放管 c 极电压正常,说明电源、亮度控制及亮度通道正常,再查显象管加速极电压也有近300V,且阳极高压亦基本正 The issue of Comrade Ren Liping comrades mentioned in 2004, “slow imaging ” reason in addition to damp seat, but also with the power supply filter capacitor leakage and switching power supply positive feedback capacitor has not been activated, which is true, but I encountered a few cases of color TV “slow image ” is neither the seat tube leakage, nor is the capacitor leakage or not activated, see the following example. Example 1 a Fu-HFC2168 color TV, there is no sound when the boot image, about 2min (minutes) before slowly showing a very dark blurred image, as time goes by, the brightness increases, the image gradually clear, began to change the tube seat The result is still the same. Just after the start of the investigation to see the second c-tube voltage is normal, indicating power, brightness control and brightness channel is normal, then check the picture tube acceleration voltage is also nearly 300V, and the anode voltage is also positive
