I am on my 2nd ATV the firstone Bricked on me I havd it plugged in 24/7 and after 5 months it stopped working. No Lights, Nothing. Luckly for Me it was still under warranty.
So I took it to my local Apple store and had no problem getting a new one. B)
As everyone knows the ATV's get REAL HOT :). and Even when they are in standby moe they are HOT!
When I got my 2nd ATV home I also Purchsed a A/C Remote Control to Turn ON/Off The Power to the A/C Plug. What I do now is put my ATV in standby mode then click the remote control to cut the power to the Unit. Is this a good idea to extend the life of my ATV ? or is this doing more harm then good ?
You shouldn't have any issue just disconnecting the power, though if you are worried about it there is a 'shutdown' option located in nitoTV --> Settings --> Utilities. Selecting this prior to powering off the AppleTV will do much more to protect the AppleTV than the standard 'standby' option.
