It is not right; the Prophet (Sallallahu Alaihi Wasallam) said:
ان ھذا الأمر دین فانظروا عمن تأخذون دینکم (مشکوۃ)
These matters are related to religion, so you should see from whom you are taking your religion. (Mishkat)
The matters of religion should be learnt from authentic and pious people.
(2) Television is a tool of entertainment and enjoyment (lahw-o-laeb). It is most widely used for unlawful and prohibited things. If lawful matters are learnt from authentic people then also it is unlawful to listen it through TV, since it includes more or less haram thing. And by using TV a person slowly starts watching other programme as well.
