I didn't have a chance to deal with this last night. Checked my 6100 this morning. Dead. As in no lights, no nothing. Held down power button, nothing; tried removing and reinserting card, nothing. Power-cycled the receiver. Nothing.
Called Bell, spoke with a friendly and knowledgeable tech support guy (for once...). He confirmed there was a software upgrade yesterday but didn't have more details about it. He had me plug the receiver into a different outlet, remove the power bar, etc. No difference. He then called his supervisor to arrange for a replacement receiver to be shipped. While he was waiting for a supervisor, I power cycled it again and it came back to life and locked on the signal. (I should mention that I own, rather than rent, all my receivers).
The interesting thing was that he said there were a *lot* of 6100s which were completely dead after this event yesterday and that they had a lot of calls like mine (but which didn't end happily) which resulted in new receivers being sent out. Also, his wait to talk to a supervisor was going to be about 40 mins, so thankfully we aborted the procedure. I requested a credit and he applied for a credit of about $2.60 (roughly 1/30th of my bill) - technically only one of my receivers was down so he probably didn't have to do that. Although the time I spent on the phone was far more valuable than that.
I'll add this whole fiasco to my general list of rants about Bell and refrain from doing so in this thread.
