Not something I can test because of the way I have everything setup, I can't use Hdmi-CEC as it just confuses the hell out of my tv.
Anyway please enable debug logs and then use Hdmi-CEC and lets see if it gives any clues.
Also please let us know which make and model of tv you are using and I will pass the info onto the guy that knows Hdmi-CEC better than anyone else when he gets back after New Year.
The tools I use. Epson TW7100 (HDMI LINK), Samsung UE32D6500 (Anynet+), Denon AVR X2700H DAB, ultimo 4k and viper4k V40 receivers wake up from standby, only pulsed 4K does not!
Thanks in advance!
