Loss of signal, Input 2

After a recent storm we have lost signal on Input 2 of our DVR.  This only happens when tuned to channels 290 (or so) and higher on Input 1.  For example: Input 1 on 241, Input 2 has signal, Input 1 on 296, no signal on Input 2.

I have done a restart of the DVR and it didn't fix anything.

All cables are connected and tight.

2nd receiver on the same dish has no problem.
