I went to watch an R15-500 that I hadn't watched in a few days. No video signal, just a chirping about once a second from both the left and right speakers, with the Record light flashing dimly at the same cadence. No change if I reset, unplug and plug back in, etc. The chirping happens immediately when it's plugged in, I don't get the blue setup screen, etc. So I pulled down an R15-500 from another room I haven't been using lately since I upgraded that location to SWM and an HR22, but had some old programs to watch, so I haven't yanked the card yet (so it's still a live account etc.). Plugged it in (using the same analog stereo audio & svideo out). Exact same problems, except that the record light isn't flashing on this one. All other symptoms are identical (chirping, no video output, no startup screen on reset or unplug and replug, etc.) I swapped power cords, tried two different outlets (TV plugged into same outlet is fine), but both seem DOA. Power light never turns blue on either of them. This is very very very strange. Anyone else seen this? Haven't called D* yet, I came here as I thought maybe there was some April 1st bug or something that had hit a large # of users, but didn't see anything obvious from scanning recent titles. [Edit] Note these are of course not SWM, I'm running dual tuners, dual coax, two of my three HR's are running SWM but that's off the back of a cascaded 6x8 multiswitch (was set to do 6x16 but they didn't have any off the track) so the other 6x8 multiswitch is fully non-SWM and has been working totally fine, it's also fine for the third HR that's using two coax and not SWM.
