Travel Much? Maybe you need a "FAKE TV" ?

Afraid of burglars entering your house when you are away overnight?   This product looks like just the thing (I sincerely like what I am seeing, I don't sell them, I am not affiliated with them in any way).
I bet one could be made with an arduino and an LED array? 

Fool Burglars with FakeTV!

Most burglars will not risk prison by breaking into an occupied house.  So when a prowler sees that flickering glow that means someone is home watching television, he knows to move on to an easier target. But now you can outsmart him with a FakeTV.  FakeTV simulates...

A lot better then leaving a TV on a timer. Most burglars assume that when a TV is on that someone is in the house watching TV, and they don't rob the house. Most TVS also don't have an option to leave them on a timer, and you can't put them on a timer like a lite because you have to press the button after plugging it in. Really enjoying my new faketv.

True, the timer would have to be rigged to the On/off button(s).

BTW:   this is a real product.   The product FAKES the flicker of a TV.   This shouldn't be too hard to emulate, do you think? 
.  Faking the flicker should be pretty easy with a few 555s (or similar) and a breeze with a µP.
.  Faking the sound¹ would probably be more difficult, but within the capabilities of most DIYers that could handle the flicker design/program.
¹ It would be very muffled sounds, not anything intelligible, which should make it a lot easier. Throw in some muffled applause and/or laughter every now and then.

One could get a fairly decent psuedorandom flicker from a LM556 or LM558, I suppose, but it might not be random enough to fool someone outside looking for it.  The Fake TV that I came across, does not use sound (that I know of).

fairly decent ought to be good enough. ;) Unless the burglar is very motivated, I don't think s/he is going to spend the time and/or brain-power to analyze the flicker. Of course, if the burglar is motivated enough, nothing will stop them.
.  I'll also bet a nickel that the color of the light is not very important, ie, the TV "tube" puts out a more-or-less white (gray) color on average (most of the time).

.  hmmmmmm. How about:  At any point in time, the screen, as a whole, is probably putting out approximately equal amounts of Red, Green, and Blue light.
How non-specific!

At any specified location in the space-time continuum, the screen as a whole is likely emitting approximately equal numbers of photons at the wavelengths 650, ,510, and 475 nm.

.  Yeah. What she said.
