hmm, I don’t power off the TV, just standby. How long does it take for you to run cec-client, mine always takes about 3-5sec to open the bus - seems strange to me. Some kind of comm problems on the bus may result in loosing commands. Sometimes is works issuing the command twice, sometimes nothing happens after 5 times. This is anoying, because it would solve my problem very smart rather than navigating the menus using adb sendkey.
