I sure hope someone here has an answer or at least some info for me. Last night I unplugged my Series 3 to move it into a different room. After plugging it in, it rebooted all the way to "Almost There, just a few minutes more" and just as it's about to be done...goes to "Welcome Powering up" And it will do this forever. However if I pull out one of the cable cards so there is only one in the bottom (doesn't matter which cablecard is in there), it boots up fine and works fine with one tuner. If I try to insert a second one, I get an immediate reboot and it starts looping again. Frustrating as I'll get out since it seems you're waiting forever for these to boot up. Anyway, just didn't know if someone knew anything about what the culprit could be, or should I just use one cablecard and be done with it? Thanks a ton in advance!
