Hey there, Cheri Torres with DISH Network Customer Service here. It sounds like you are going to need to change your TV back to the proper input or channel. If the TV remote is not working to change the channels you can also use the buttons on the front of the TV. First look for a button listed as either input, TV/video, source or AUX. When you press this button it will start cycling through all the inputs available, make sure to cycle through them slowly because it make take a couple seconds for the picture to come in. If you do not find a picture on any of the inputs you are going to need to try the different channels. Normally for a TV where the receiver box is the TV should be set to channel 3 or 4. Once you have found your DISH Network picture you will want to make sure to push the SAT button on the DISH remote so that it doesn't change the TV channel again. I hope you find this information useful and if you have any further questions or concerns please let me know. Thanks. :)
