From the above seems to show the failure, the author estimated that the fault is mostly the work of the subsidiary CRT circuit damage occurred because the cathode-ray tube voltage of the focus is very prone to failure similar to the above phenomenon, the phenomenon that gave rise to such failure is due mainly to display work over time, then the CRT focus very near the jack attached to a lot of dust very easily, which encountered wet dust easily lead to the air tubes of focus very significantly decrease the performance of socket contacts, then a cathode-ray tube focus to the natural voltage decline will be affected down, so that we could monitor the performance will be prone to poor focus, image display is a relatively vague.

从上面的显示故障现象来看，笔者估计该故障现象多半是显像管附属的工作电路发生了损坏，因为显像管的聚焦极电压十分容易发生类似上面的故障现象，引起这种故障现象的原因主要是显示器工作时间一长，那么显像管的聚焦极插孔附近很容易附着不少灰尘，这些灰尘遇到潮湿的空气后容易导致显像管的聚焦极插孔接触性能大大下降，那么一来显像管的聚焦极电压自然就会受到影响而下降下来，这样的话显示器也就容易出现聚焦性能不好、图象显示比较模糊的现象了。
