Press and hold the clear tv button at the top of the remote until the other clear buttons light up. The tv button should be blinking. While it is blinking, press in the code ( http://www.mydish.com/support/apps/remotecodes.... ) and then the # button. The tv button should blink off at this point. Try the power button and volume buttons to make sure that they function. Once you've verified that they do, press the SAT button to get it back in satellite mode and the functions should still work.
you can also try a scan mode on the remote (do this for each tv)
press, and hold the TV mode button until all the lights come on, then release (TV mode light will flash)
press and release the Power button (TV mode light will be on steady)
now press, and release the channel up slowly and repeatedly until TV device turns off (TV mode light will go off then back on with each push)
when the TV turns off, press and release the # button on the remote to lock in the code
