Yesterday morning sky+ box wouldn’t switch on and it sounded like the hard drive was constantly running, assumed this was the box just updating so not too worried, got home last night and hard drive still whirring away but box switched on ok. got up this morning, hard drive whirring away and box wouldn’t switch on, switched it off at wall for 5 mins then switched back on, after about 5mins box finally switched on but no Sky+ facility, couldn’t access planner, pause or rewind current program, any ideas of problem/solution or will I have to spend hours on the phone to Sky then pay £60 for an engineer to tell me I need a new box?
