@dusty_miller0Do a web search for "visio m55-f0 turns on by itself" and you will find that you are not alone. It is either the Rogers STB or the Nvidia Shield or both that are the sending input to the TV, and if the TV was set to that HDMI input before it was turned off it will respond by turning on. There are a few solutions:
1. Before turning the TV off select an unused HDMI input
2. Turn CEC off
3. Change the TV from eco mode to quick start
No need to disable wifi as that is not a contributor, it is all due to the design of the TV.
Just a quick update.
Have set TV to quick start and as stated had the phone reset. CEC has been disabled for awhile
The TV has not turned on the last 2 nights and will start plugging back in on Thursday night.
FYI. Last night I hooked the Nvidia Shield back up and left all else the same as last reported. HDMI left plugged into rogers box CES disabled and quick start on. Phone also plugged in
Iplayer what's the difference between ECO and quick start?
So far so good. Thanks again and I will keep you up to date
...what's the difference between ECO and quick start?
Your TV's operating manual will probably tell you that ECO uses a bit less power and it takes the TV longer to start up. Quick Start probably sends a bit of electricity through the TV's electronics so that they are kept warm for a faster start. You can test this by plugging your TV into a Watt Meter.
The response from @57 was textbook, and right on. Not sure if you were asking about that setting on your TV or the Ignite box. I have my Ignite box set to ECO and it will take nearly a minute to produce audio/sound. With quick start it is a lot faster. The terminology make be a bit different, and I do not have my TV turned on right now to check.
Same as week ago with everything except the sound bar plugged in. No other setting changed, and working as expected. It seems that all of a sudden everything started working the way it should as if a secret switch was turned on. Would love to know what is/was? Another week of isolation for the sound bar and I'll get back to you.
Thanks again to ALL who helped
Some TVs have a "signal sensor", so that if the HDMI (or sometimes other input) sends a signal to the TV, then the TV will turn on (wake up) by itself. I'm assuming that when the IgniteTV box updates, or whatever, that the signal becomes active. (I don't have IgniteTV)
You may wish to check to see if your TV has a menu item that reflects this sort of "wake up" and turn that off. It may also be related to HDMI-CEC settings in the TV. If you don't need HDMI-CEC functionality, then turn the feature off. See the following FAQ, item 4 on the topic:
