Independent TV — black screen showing after every few seconds

Address:

63/2,AISHBAGH,OLD COLONY, Lucknow, Uttar Pradesh, 226004

While watching the tv i am getting continuously black screen after every few seconds and therefore unable to watch the tv. I had recently taken this connection and having this issue since then... If this connection goes like its going currently, i am afraid i need to change it sooner then. So i am looking for somebody who can resolve this issue asap.
Take it as high priority
