美国B超ADR 4000发生拉片监视器无光无图,外接监视器B超图象区域为空白,我们将修理的经验介绍如下: 分析:由上面的故障现象,我们首先想到是拉片监视器和存贮器公共电源出了问题,见图1。经测量,公共电源的交流保险丝开路,给存贮器供电的主电路保险丝F_2正常,故可初步判断是拉片监视器供电电路出了故障,见图2。给高压包供电电路的保险丝经测量是正常的,既然监视器无光,则高压包一定无
The United States B-ADR4000 occurred pull-tab monitor no picture, external monitor B super-image area is blank, we will repair the experience described below: Analysis: From the above symptoms, we first think of is the pull-tab monitor And storage of public power out of the question, see Figure 1. It is measured that the AC power supply of the public power supply is open, and the main circuit fuse F_2 supplying power to the memory is normal. Therefore, it can be initially determined that the power supply circuit of the pull-tab monitor has failed, as shown in FIG. 2. Fuses for high-voltage package power supply circuit is measured by the normal, since the monitor dull, the high-pressure package must be no
