Since the streaks of light are of the same color as the tv, they are of the same light emitted by the tv.  Something in the optical path between the tv (or streetlight, etc.) and your retina(s) at the back of your eye(s) is causing some diffusion of the light.  This could be in your eye(s); on the surface of your eyes; or on your glasses, if you wear any. 

Obtain a little, bright, LED flashlight or keyfob light and in a dark room look at it from several feet away.  Do you see a point of light or a vertical line/streak of it?   Try these tests.

1. Close one eye then the other--does the effect change or go away and come back?

2. If your have glasses, hold them in front of one eye, one glass lens at a time, and rotate it.  Does the pattern rotate with the glasses or not?  Is it associated with a particular lens, or with a particular one of your eyes?  If with the glasses, the glass lens is scratched or improperly made.

3. Vertical diffusion would generally indicate that there is one or more horizontal scratches or streaks somewhere in the optical path.  Are your glasses scratched in this way?  Might you have scratched your cornea (the surface of your eye)?

4. There are also conditions within the eye (floaters, etc.) that could result in this effect, again by scattering the light on the way to the retina.

I'd suggest you have an eye doctor have a look at you, just to be safe.
