长城 C—1453A 是具有节能、多频扫描等功能的35cm(14英寸)彩色显示器。经多年使用后,故障率相对较高,下面介绍其常见故障的检修方法,供维修时参考。1.行输出变压器损坏的检修长城 C—1453A 彩色显示器,使用几年后,行输出变压器的损坏率较高,我们学校一个计算机房的五十余台长城 C—1453A 彩色显示器(以下简称彩显),己有十多台的行输出变压器陆续损坏。损坏的情况都是在聚焦电位器一方的上端穿孔或开裂,对散热片上用来固定行输出变压器的一颗螺钉的尖端放电打火。其他型号的彩显行输出变压器的损坏率相对很低。
The Great Wall C-1453A is a 35cm (14 ") color display with features such as energy saving, multi-frequency scanning and more. After years of use, the failure rate is relatively high, the following describes the common troubleshooting methods for maintenance reference. 1. Line output transformer damage repair Great Wall C-1453A color display, the use of a few years after the line output transformer damage is higher, our school a computer room of more than 50 Great Wall C-1453A color display (hereinafter referred to as color display ), Have been more than a dozen sets of output transformers one after another damaged. Broken holes are either punched or cracked at the upper end of the focus potentiometer, sparking the tip of a screw used to hold the line output transformer on the heat sink. Other types of color display output transformer damage rate is relatively low.
