I decided to move a HR20 from one shelf to another. That turned out to be a bad move. I have lost the signal completely. I did a menu reset and pulled the power just after the front-panel light went out, disconnected everything, reconnected everything, and was then treated to hours of no signs of life other than a dim led on the left-most button. I unplugged for a day and it eventually came up, unable to find anything. The menu has just one entry in it and the date has defaulted to 12/31. This unit had done much the same thing before, months ago, and I tried a forced download 0-2-4-6-8, which cured the issue. This time it can't see the sats to even get a download. I have tried reconfiguring, removing BBCs, replacing BBCs, etc. The other DVRs on the same switch have no issues. I have come to the point of accepting that there is no hope of ever recording on this unit again, but what would be nice is if it would let me get to the recordings for playback, but it is stuck on the "Advanced Program Guide Data" page at 0%. All I can say is its a good thing I double-record everything. Is there a back-door menu code or sone other hat trick that will get this POS off of the APGD page and let me at the 400 hours of recordings? Or is it simply "buh-bye" time for the old girl?!pusht!!pusht!!pusht!
