We have a Sony 14 inch colour television which has somehow had the child lock activated errorneously when we were testing all menu options. At the moment we switch on the tv and you cannot press any key/button except on/off button. How do we remove/deactivate this. How eeprom can be reseted or replaced and where is it located on the television set.
