The case is clipped together as well as screwed, and there are cables that
link the display and keyboard to the processor board.

You need to remove the 4 corner screws on the bottom (it sounds like
you've done this) and then pull the 2 parts of the case apart (fairly
hard), starting at the left hand side (the side with the BCR connector and
the modem switches). Then 'hinge' the 2 parts apart, taking care not to
damage the cables (26 way ribbon to the display, 2 bundles of wires to the
keyboard).

Display problems (assuming the rest of the machine works) tend to be
either the interconnecting cable/connectors or a loss of the -ve supply
rail. I have a technical manual (with schematics), and can look up the
fault tracing procedure for you.
