(I've even heard stories of direct sunlight streaming through a window confusing the infrared sensors and turning the TV on-though I've never experienced this one myself.) You might even have a neighbor using a universal remote that's sending compatible codes to your TV next door-it's rare, but it can happen. If you have a Vizio in the living room and a Vizio in the room across the hall, for example, your remote signals from one room could affect the TV in another. While most TVs shouldn't interfere with one another, TVs of similar makes could easily intercept remote commands from each other if they're close by.

If your remote is running low on battery, it could be sending out errant signals as its power fluctuates.
