I don't have a solution for you, but I am experiencing a similar problem. So far it is one only one channel, TBS, when I bring up that channel, after about 3 seconds there is a "click" and the language changes to spanish. The commercials are all in english, the TV SETUP is set to English but this channel changes to spanish. Comcast service people tell me it's the TV, but it has happened on another TV in our house too. This problem comes from comcast and they should stop it.
