a friend of mine has 255 and was trying to put in data and failed every time he stored them 100% but when rechecking data all changed.iknow he was doing it correctly as i was talking him thru.
finally i told him to unplug aerial then re enter codes and store ,plug in aerial and hey presto picture and sound. so are n*l doing something to the signal to screw it up ? so next time i see him i will give him e400
