Local channels freezing

is this happening on just one receiver or all of your receivers?  other channels OK?

It is happenning on more than 1 receiver.  It is not happening on other channels.

transponders(?) 18 and 28 are zero and 26 is 70.  The rest are above 90.

It is happening on all our local channels also.  The other channels are fine.  Please help.

We reset the receiver which seems to have helped.

pleas provide us with your signal readings

You'll find these readings under "Menu" -> "Setup" -> "System Setup" -> Satellite -> "View Signal Strength". Note the "+" and "-" symbols next to the "Satellite" and "Tuner" entries where you can toggle the readings between the various satellites and both DVR tuners. If you have a DVR it's important to check BOTH satellite tuners. 

Fill in your readings for each satellite and tuner on the new post you create, using the example below as a guide. (The example below is only an example and not a form that will appear in your post unless you "cut" and "paste" it.) A properly aligned dish will show 80-90s on most of the relevant transponders (although some will be low or zero):
Satellite transponders (32 total at 101º)
[Most of your standard definition channels are beamed from 101ºW]

I already provided the information. Please see reply #3 at 6:32 pm EST

I live in the Denver, CO area and I began noticing the freeze up problem today 11/07/2011 on all local channels at around 4:30 PM.  It may have started earlier in the day, but this is when I switched to the locals for the news.  It took me a while to realize that it was only local channels.  I verified my signal strength levels were all normal.  I have a HD-DVR  HR21-100.  Hope this doesn't take a week or more to fix like the same problem that was reported by many people the last week of September into the first week of October in the Detroit area.
