I feel your pain ktadd and Arcade. This is a DISH box problem and is in no way related to LCD back-light issues. I can tell you that even the RF remote experiences the delay in response, and sometimes even a reboot won't always fix it. The "K" can just have a bad slow remote day and we have to live with it until the next day or several hours later. The processor is probably busy or too busy doing who knows what during these times (a previous poster suggested the banner ads issue, and it sounds reasonable or other firmware issue).
I think folks have to give us credit that we know what we are talking about and have eliminated the back-light issue. In addition, the problem is DELAY in response after hitting the button ONCE, not that the signal is being blocked. Oh, the signal did reach the box alright; its just taking is sweet time to process it.
