Correct:

Anna likes to watch a TV program.

Explanation:

1. Please always be consistent with your verb tenses.
    Examples:  watched  -  watch (the sentence is in present tense)
                    open       -  opened(Present or Past based on your context) 
           
2.  Putting "program" after the TV is much better for it specifically shows what you watch on the TV.
