Parental controls -> losing TV code

These may be unrelated and just symptoms of different issues. But since we enabled parental controls, we seem to lose the remote code that controls the TV functions. This is a Samsung TV and the first code was the one that have been working for the last 4+ months. We have tried others and even when going back to the original, everything works well for a couple of hours and then it stops working.



Our last resort would be to remove parental controls, but that kind of defeats the purpose.
