Try this out.
To Manually Unpair 50.0, 52.0, and 54.0 Remote Control
1. Press and hold the SAT mode button until all mode lights on the top of the remote light up.
2. Press and hold HOME and GUIDE at the same time for 5 seconds.
If successful, you will hear three descending tones.
There we go that's the code.
Thanks all, but in the meantime a strange turn of events. I went to the TV that uses the remote and used it to turn on the TV by pressing the TV button to make sure I wasn't doing anything "general". Just wanted to turn on the TV to see where things were prior to a Red Button Reboot. Once on there was a sleep screen saver was on the screen. I went to turn on the DVR itself by first pressing the SAT button, then I would press the power button. When I pressed the SAT button the remote quickly did the three tone link noise and now it's linked and working. <insert null bewilderment here>
Looks like things, the DVR, needed to sit overnight. Maybe even the "Nightly Reboot", which around here can be anytime of the day when you want to watch the thing, was what did it? That's the only thing that I had not done previously. But being "unlinked" the strange thing was that the stats for the remote were on the "Diagnostics" page. And once linked again there was no change. <insert "Twilight Zone" theme here>
When things go wonky with DISH gear the "fix" or "outcome" never surprises me. I hope by this thread anyone in the future who may encounter this problem at least gets some info, the "Delink Code" and a direction other than what I found.
Thanks all for replying and trying to help!! We did create a thread that may give someone else "Food for Thought".
