Can anyone tell me what the TiVo Roamio Internal Blue Light means ? ? ? (the INSIDE one which can be seen through the top, not the "downloading" front light one) (Current suspicion is it means "start-up prevented, due to low power", since upgraded HDD is 6.5 watts more, and power brick has only a 24 watt total rating, and maybe my house VAC is on the low end to start with) Is this cause for concern? Something I should ignore? Return it? Suggestions? BACKGROUND INFO: About 50% of the time when I unplug my Roamio (3 week old, OTA model, LTS, with 3TB internal WD AVGP) then plug it back in, it does not start up or show any signs of life when I press any of the remotes buttons. It will stay completely off, with only the INTERNAL blue light turned on. It will do this, regardless of the duration I leave it unplugged or plugged in. Unplug and plug in 1 or twice more, than it starts up.
