Just a wild guess: Check the channel-up and channel-down buttons on your
TV. They should "click" when pressed. If the button is stuck down, or
the switch below the button is damaged, you probably won't feel that
"click", or it might have a "mushy" feel.

As I recall, years back we had a KV25XBR with a shorted channel switch
that felt just fine mechanically.

Such things do occasionally happen. And that is why I used the term:
"Probably"...
