So I woke in the middle of the night and saw all the lights on my Series 4 lit up. I thought "that's strange' and fell back asleep (eventually). This morning I wake up and only a solid amber light is on and there's no picture, just a "No signal "message on my TV. I am taking this to mean the hard drive is dead (it's making serious noise). I've tried cycling the power a couple of times with no luck. Is it really dead? Is there something else I can try? Thanks in advance for the help.
