I have owned the 48"v2+ for about eight weeks now. At first I had the problem of various channels coming on and off at times it was not programed for. After cycling through the times and changing the hour as instructed sometimes multiple times it would work fine till the next time I changed the program. This time I can't get the reds and greens to go off no matter what I do. Do I have a defective unit since this is happening every time I change the program.
