I updated KD55XG9505 to PKG6.5016.0631EUA today. There is now a completely new channel guide and I can no longer access catch-up TV which used to be on the blue button when the guide was active.
@Marty.S if the update doesn't solve that for you, try clearing the cached data or factory resetting the TV to "settle in the update" as people wholesomely refer to it. 😂
