your initial response seemed to overlook the fact I didn't have the problem BEFORE i upgraded to 10.2.
Diana.McCall has been actively involved in many of the posts since the 10.2 insomnia issue occurred.
Her findings definitely err on the side of it being an app scanning issue, and while my LAN setup would also support such a theory... the other ATV in my life, would not (as she knows from another post)
while I agree my television model may now be to blame, would Apple kindly remove the anti LG TV feature they added to 10.2, because I was very happy with 10.1.1 and the ability to leave my ATV plugged in and asleep.
In terms of it being a first world problem, for me it isn't as my ATV is switched off when not in use (along with the media amp)
However my parents and others who have approached me for advise as to why their's have developed this ON like status, would like to know what changed and caused it.

* I was not the original finder of the HDMI solution, I simply tried THAT suggestion (along with the many other suggestions out there) and also found a connection (or lack off) is what is required to keep the ATV off since upgrading.
