The choices of symbols (A TV in this case) our subconscious uses to express emotions or tell us something can seem very odd sometimes. The subconscious is very childlike in a lot of ways, seeing things in a very black and white, straightforward way; probably choosing the TV as a symbol because it's one of the things it recognizes as something that is switched on and off a lot, at will. Maybe trying to tell you that you can't do the same thing with your feelings/emotions, no matter how much you try?

P.S. I'm jealous that you have a pocket PC; I want one!
