Check to make sure the 'bars' on the shutter are all the way to the left and invisible. If you can see them, try pushing gently with a fingernail until they slide all the way left. This may unlock the camera.
Check the release capacitor on the bottom. If you see any green on the leads it is bad - heat one of the leads with a soldering iron - if you smell 'fish' then it is bad. If leads have leaked onto small circuit board, try cleaning with isopropoyl alcohol. If leakage is too bad, board will have to be replaced. Part is of course no longer available, as Minolta is out of business.
