我有运行Raspbian的RPi B通过HDMI连接到我的LG电视.我成功编译并安装了cec-client,我可以使用命令echo“on 0”|轻松打开电视cec-client -s,但当我尝试使用命令echo“standby 0”|关闭电视时cec-client -s我得到这个输出：

没有任何反应.此外,我只使用CLI,并在一段时间后RPi将电视放入空白屏幕保护程序,但我无法弄清楚如何在我的命令下立即执行此操作.
最佳答案
似乎libCEC没有任何问题.然而,LG TV模型的HDMI-CEC实现可能只是忽略了备用命令.您应该使用其他符合HDMI-CEC标准的设备测试Raspberry Pi,以检查备用命令是否正常工作.
