I have a Pi (with Raspbmc installed on it) connected to an LG TV. I disabled the CEC options in XBMC related to turning the TV on/off. However, the Pi keeps turning the TV on when rebooting. I can confirm it's the Pi and not XBMC as the TV comes on before XBMC loads. Is there any way to prevent Pi from turning the TV on? I understand that it sends a signal through HDMI when it comes on, but does it send a "wake up" signal? If so, is there any way to prevent it? It's not fun to come back from work or to wake up and see the TV's been on for hours... Thanks!

If it helps, the functionality causing this is HDMI CEC. – Jivings♦ Dec 2 '12 at 9:17

Try editing /boot/config.txt to include the line

hdmi_ignore_cec_init=1

If you're using OpenElec, the file is /flash/config.txt

More info on config.txt options can be found on the elinux wiki pages

Nice, I didn't know about that option. – Jivings♦ Dec 2 '12 at 19:18
Thanks! That's exactly what I was looking for. – Mircea Dec 8 '12 at 6:34
