I have a 4-tuner Tablo for about three months now - it’s been working fine until three days ago when it stopped responding. The blue light was on solid. If I momentarily pressed the reset button to restart it, it would not respond. I finally just pulled the power cord then plugged it back in, then it came up and all was well, until the next night. I was watching a recorded show - when it finished I tried to delete the episode, and just then it appeared to hang again. But this time it was different. I could not access it on any of my 3 Roku’s, my iPhone, or via my.tablotv.com . However I could still ping its IP address. I also have Tablo Ripper installed and it could still access recordings on the Tablo. The other thing is that this time the blue LED was blinking in a sequence - 3 fast, 3 slow, then 3 fast blinks, followed by a slight pause. This time I was able to cleanly restart it with the reset switch. I never really paid much attention to the temperature until just now - the enclosure didn’t feel too bad but the bottom seemed fairly warm to the touch but not so hot that I couldn’t keep my fingers on it. I positioned it sideways and it’s been fine for the last couple of days and the bottom is definitely cooler. If that’s all it is then I’m fine with standing it vertically.
My main question is - what does this LED blinking 3 fast, 3 slow, then 3 fast mean? Is it related to temperature or some other potential problem? If it’s temperature I’m surprised it took this long before there was a problem.
