we have a toshiba tv, 35 in. maybe 6 years old. anyway, we also have satellite tv. the on/off and volume controls do not work on the sat. remote although we def know it is not the remote. is is possible that the sensor of the tv. little red light onthe tv. is no long able to pick up on the remote? My husband says he never heard of such a thing, but , the fact is that the remote works when it is nin sat. mode which is to aonly change channesl. you need to be in tv mode when you turn on/off and volume and that is when we have problems. any suggestions.
