Vizio M470NV is an economy class LED TV made by Sharp for Vizio.
The main board in it suffers from a few problems that are actually common for the Vizio LED TVs made by Sharp and based on the same design and built with the same pool of components.
It took time to TV repair shops, but now repair services and possibly even exchange boards are starting to become available.

I hope you get a response. I am having the same issue. It turned off on my this morning @ 0600 and then after getting home from work I was cooking dinner and was wondering who turned the TV off. It did it again.
Then it happened about three hours after that. I wish I knew what the problem was!

Let's try this first:
Testing remote control:
The remote control puts out IR (InfraRed) signal that human eyes cannot see, to find out if the remote is sending out the signal or not you just point the remote at the digital camera's Lens (Digital Camera can detect IR), you should see flashing light on the camera's screen when any one of the remote button is pushed. If you do see the flashing on the camera, then the problem is in the TV IR receiver or the main logic board; more troubleshooting with scope will be needed to look at the signals.
