Fallout 4 miscellaneous world objects

Electronics
Televisions are miscellaneous objects spread throughout the Commonwealth. They can be powered in settlements, and will display the message "Please stand by" in the standard Fallout fashion.

One interesting thing to note is that, when televisions are powered down, you'll notice they display what appears to be a reflection. Upon closer inspection however (In Sanctuary), they are actually showing a different location entirely. each one is different as well. Where are the locations they show? That's still a mystery.
