Tv is unresponsive
Does your set have a reset button on it? It sounds like we had the same problem from the beginning. In fact, we have bought and exchanged the tv 3 times because we thought maybe we just had a lemon. The picture would freeze and no buttons would fix it. We read in the owners manual about the reset button -- a tiny hole in the top of the power button on the right side of the tv. You can use the end of a paper clip and stick it in the hole to reset the tv. The tv powered off and then the remote and all the other buttons worked. Ours is still in the warranty but for the first month, it seemed like this happened at least 5 or 6 times. Haven't decided if we want to try to exchange it again or just live with it. Other than this, we love it!
