I had this remote working and something happened where i can no longer program it. I have pushed the setup button and it lights up for a split second, then I press the tv button to program it. well i don't have the codes so i do the part where you press the power button until the power turns off. The light above the tv button will blink after the first try and then on the second try it will stay lit for several seconds. Im not sure what i am doing wrong, but it just won't work. Any suggestions would be nice.
