Do you have other devices connected to your t?
Such as a router, a decoder or an apple tv? If you have, restart them and change the batteries in the remote. You may think that is a silly suggestion, but changing batteries in remotes has helped me more than once. Oh and do not forget to check all cables and connections as well as the power. This method does not always work the first time, in my experience it works. Patience and coffee.
