15px;">首先进入维修模式，对日立彩超EUB6500进行自检，结果显示一切正常。由于是间歇性故障，我们只能长时间开机观察。在一个多小时内，我们观察到了两次异常发生。在故障发生的同时，我们注意到，与彩超联接的工作站上的画面并未出现异常反应。由此初步判断机器主机正常，问题可能出在显示器上。</span></p><p><br /></p><p><span style="font-size: 15px;">另外发现在关闭日立彩超EUB6500后(机器下角电源开关不断开)，显示器上出现“noinput”字样，由此推测此机器的设计可能和电脑类似，显示器和主机各自有单独的电源供应。打开显示器后盖，我们看到由主机中引出的一根电缆线包括了</span><span style="font-size: 15px;">DC12V电源输出口，VGA端口，数据排线接口等。</span></p><p><br /></p><p><span style="font-size: 15px;">我们用一块12v的直流电源适配器为显示器供电，并用VGA视频线将其与一台电脑主机相连接，即用它来代替普通液晶显示器。开机两小时，未见异常。因此大概可以判断，问题是出在VGA视频线或者是两端的接口上。</span></p><p><span style="font-size: 15px;"><br /></span></p><p><span style="font-size: 15px;">用万用表测量后发现，视频线一端由于弯折而产生了接触不良。咨询厂家，他们对整套电缆的报价是上万元，而我们通过观察断定，联接超声主机和显示器的视频线是独立的，因此我们用了一根三米长的VGA视频线代替后故障排除。</span></p><p style="box-sizing:
