You stated in another post regarding discretes for a Mitsubishi WD-65000 that if you hit Ch+ or Ch- that it switches the input to ANT, then you must cycle through inputs using the Input+ and Input-.

I tried this out with the 65000 but it didn't seem to work. Anytime I hit Ch+ or Ch- it would only display my current input, not switch me to ANT. My question: must there be something connected to the ANT input on the back of the TV? Or should Ch+ or Ch- always switch to ANT regardless of having something connected to the input.

Thanks.
