Aerial/shared TV Remote.
Yes, Video recorder & dvd player.
Disconnected both, TV changed perfectly about 5 times then I selected channel 5 the blue banner for that channel is displayed but no change, very similar to before.
Yes it is stuck.I think on channel 2, the channel 5 blue banner still displayed. but will not respond to remote for any changes.
Thank You Anthony for your help, I think I will invest in a new set, I assume the fact that it changes after being turned off for 30 mins. it allows the function board to cool down, I'm 79 years old so I don't think it wise to start going into the back of the TV. Thanks Anyway, I will leave my ratings.
