I just witnessed how an Amiko Mini HD can completely lose it's time/timer memory without being unplugged. Before I tell you, promise not to laugh.
I do watch "some" of today's TV, but when I want the TV equivalent of "comfort food", my menu of TV includes MASH, Twice in a Lifetime, CBS Sunday Morning,
PBS's "History Detectives" Get Smart, Lost in Space, and, even an occasionally banked-up on hard drive, "Little House on the Prairie" (which I grew up watching in elementary school age years) with Lesea carries this last show on it's 99W feeds.
Tonight, I was setting another satellite into memory when the timer would have kicked-in for this feed. I was moving the dish via the V-box to the Birdview, searching for a signal on another bird. The timer went to kick in, and the Vizio TV went to displaying "no signal." The Amiko actually rebooted itself, and having forgotten the timer was there, I had to LOOK to see what timer it was. And, after seeing what timer it was, (Little house, this time) checked the clock time. With the reboot, the time and date were lost. This may explain why I've had trouble of late with time and timers. I've been spending much time in aligning, moving the dish, etc. I wouldn't have expected that a timer attempting to override manual use would make the box reboot, but it did!
Heads up! It may happen to you!
What happens in other boxes' firmware when manual use and timers clash? Seems odd that the unit would completely reset itself!
