Television or TV as it may be more commonly called these days is not at all your friend and while yes after a hard day of working it's easy to desire to sit down and just relax in front of the TV there are several reasons you really shouldn't. 

First of TV kills your brains ability to visualize and imagine as it's all right there  whereas if you were to just hear or see a description it makes your brain have to work and create the image from scratch. 

Blue light is yet another issue as it can cause you to get lost in TV and not even be ware of it.  In other words, your eyes can indeed get so focused on the flashing lights, and sounds that you basically become hypnotized by it.   The blue light also has a negative effect on your natural sleep and REM dream patterns as well.  

lastly, if you're trying to practice say telepathy without allowing your eyes, mind etc proper rest you will find connecting to a meditative state far more difficult because tv makes it that much harder for your mind to relax. 

So if you want to live a better and happier life ditch the tv and go for audio or e-books to enjoy.  You will find yourself feeling far less on edge and more intune with your enviroment. 

If you're wondering by the way just having a tv plugged in even if it's off will still have some negative effect on you. True it won't be as bad as when it is on but it is still there. So, even if you won't quite ditch the TV at the very least make sure you COMPLETELY unplug and if possible NEVER keep the tv in the same room as the one you plan to sleep in. 

If possible you want to keep your bedroom as simple and electronic free as possible. Trust me, it helps SOOOO much with resting and sleeping. it's like night and day.
