I am having the same issue.. I have on my screen " Error Loading Page unknown error".. The other day I was watching tv and suddenly I got flipped to a different channel.. and then my buttons on my remote weren't doing anything effective.. except the mute and tv and cable buttons.. the remote lights up so I know its not the batteries.. The tv is stuck on a channel and its not one I even watch and I am missing a tv show I wanted to see right now because I cannot do anything with my tv but turn it on and off and put the mute button on. Its been 4 days now and I am on the verge of cancelling but I dont want to give up my tv.. UGH. fix this!
