Perhaps all may not be lost, a couple of the ribbon cables can be
re-inserted in their connector.
When you first open the unit, you want to remove the upper half containg
the screen itself. Gently seperating the cover you will note two white
wires attached to the screen on one end, and a small daughter brd on the
other. They are attached to the daughter brd via a small two wire
connector. DO Not try to remove the connector, instead just gently lift
the entire daughter brd(white wires attached) off the the four pins it
is spindled on, with a small pocket type screw driver. Now you can lift
the screen cover further up. There are two small ribbon cables to the
left, near the disk drive. These cables can be removed from their
connectors by gently lifting the rectangular cable clamp securing them in
their respective connectors. If the cable you have a problem with is one
of these you may be able to re-insert the cable, and gently push the
clamp back down, resecuring the cable.
There is another daughter brd in the upper left hand corner, with a
ribbon cable also going to the screen. This cable IS NOT removeable from
its connector as the previous were. The daughter brd is secured via two
small phillips screws, and once removed, the brd can be gently lifted
unseating a couple connectors under the brd. By the way this brd does
not have to be removed to insert the 4mb memory module into the connector
directly adjacant to the disk drive.
Hope your lucky and it was one of the re-securable ribbon cables.
