This is one of the problems with the Minolta electronic versions (as opposed to the SR-T and SR predecessors). Oftentimes, the electronics simply 'go'. I have found that sometimes at a camera show I will test one of the X series bodies and nothing seems to work. But, with a bit of prodding, the camera seems, eventually, to 'reboot', and then work properly.
What spiceminer indicates is a body that is simply not working. (S)he does not state whether this event is sudden or, rather, the result of not using the body for a considerable period of time. If it was being regularly used and this problem is 'sudden', my recommendation is to simply get another body (does not have to be the identical model designated). They are cheap and common. - David Lyga
