Last week someone left a nice big TV our building's garbage area with note on it saying it works great, just needs a remote. I carried it home, only to find that the power cord had been cut off. The TV had been there less than an hour. In the past year I have seen many electrical devices with the cord cut off. I always assumed that meant they didn't work.
And you can buy a new cord for your TV and have a great bargain! Someone good with electronics can install the cord, it's simple. I have done it, and I'm no expert!
Also any buildings on your property that have electricity that have been turned off to them watch them closely. In the area where I live people have been stripping the wiring out of walls of buildings to get the copper out of the wiring. Just a word of caution.
Or the TV could have belonged to a teenager who was grounded from television but insisted on having her way and her mother cut the cord off.
