-n fails to find Chromecast when TV is powered off

[xsdg]

I just noticed that specifying the Chromecast name with -n only works when the TV is powered on, and fails to find the Chromecast when the TV is powered off. However, dropping the -n arg causes the Chromecast to turn the TV on with HDMI-CEC and then works as expected.
