My 32" DYNEX TV stopped changing from one channel to another this day, when I was watching the playoff NFL game. It ended at 5:00 PM and would not go to channel 40 for the next game. 1/10/2015. It was just like that. What should I do? Oh, I did watch the game, but just going through my Directv satellite Box, by recording the game. And watching it at the same time. So, at least I have discovered how to make this TV to keep working for the time being. richard.fowler19@yahoo.com / Sacramento, CA
