一、主机显示口损坏显示口损坏,一般是带电插拔显示器信号电缆插头造成。由于AST主机和显示器电源线插头的地线与国内大部分电源插座不匹配,使显示器地电位与主机地电位存在较大的静电电位差,当忘记显示器和主机电源开关,而插拔显示器信号电缆插头时,易使主机显示部分集成电路损坏。预防措施如下。1.将显示器电源线换成能插在主机电源输出插座上的显示器专用电源线。主机的地线一定要可靠接地。2.严禁带电插拔显示器信号电缆插头。故障排除方法:1.将主机送AST授权维修服务中心修理;2.应急时可购一块300元左右的TVGA9000显示卡,插入主机内插槽,代替底板上的显示口,并将底板上DIP开关置于外插VGA卡位置,各型AST微机DIP开关位置见表。
First, the host port damage display port damage, usually plugged into the display signal cable live plug caused. As the AST host and monitor power cord plug and the majority of the power outlet does not match the ground potential of the display and the host there is a large electrostatic potential difference, when you forget the monitor and the host power switch, and plug the monitor signal cable Plug, easy to make the host display part of the integrated circuit damage. Preventive measures are as follows. 1. Replace the monitor power cord with a monitor-only power cord that can be plugged into the host power outlet. The host’s ground must be reliably grounded. 2. It is forbidden to plug the monitor signal cable lively. Troubleshooting: 1. The host to send AST authorized repair service center repair; 2. In case of emergency purchase a TVGA9000 about 300 yuan graphics card, insert the host slot, instead of the display on the floor, and the DIP switch on the floor Placed in the extra VGA card position, various types of AST microcomputer DIP switch location table.
