My 2nd Sky+ box, a V2, shows 'system fault' on screen when I press the record button. It also shows nothing in the Sky+ planner. I rang Sky, and after taliking me through the 'housekeeping' procedure (which I already knew how to do) it still didn't work. They want to charge me £65 for an engineer.... on your bike!!! I then did a forced software download which didn't work either. On the signal test screen, there's no signal to input 2. So, I switched the input 1 and 2 cables round and there's still no signal to input 2.... so I guess its not the LNB. That leaves 2 possible problems.... 1) input 2 on the receiver is broken or 2) the hard disc is broken. Would a hard disc failure cause input 2 to disappear? or does it sound more like a broken input 2? If it'll fix it, I'd rather install a new hard disc myself than have an engineer call out. can anyone help please?
