Case Name:AOC Milo Q220 error OSD locked
Case Detailed:

机型:MILO Q220液晶显示器

故障:时开机,是不开机,开机后报错OSD已锁定

检修分析:时开机时不开机,一般为电源板供电不良导致以及按键板问题;报错OSD已锁定,一般为驱动板程序及其按键设置问题。

维修过程:拆机测试按键板按键,菜单键和开机键有些失灵,于是更换这两个按键,防止后患,剩余4个按键也全部更换,开机测试,开关机OK,菜单键不能使用依然报错OSD已锁定,接下来解锁菜单键,测试全部功能OK。装机测试

 

知识拓展:MILO Q220液晶显示器报错OSD已锁定,顾名思义就是关闭所以按键使用权限,需要解锁后才能使用,此机器解锁和加锁方法一样,都是关机后按住菜单键后开机,5秒后松开菜单键即可
