I recently purchased the Sony KDS-55A2020 for my home theater and I wanted to lock it from my kids.

I've tried using the password protection scheme Sony mentions in their user guide, but it seems that it just blocks TV content.

I wanted a way to prevent the kids from turning the TV on period. When I had my Hitachi 51S700, I could set the TV to be locked, where if you attempted to turn the TV on without the password, you didn't get a picture.

Is there a way to do that with the 55A2020????
