Can you be a little more specific about your rescue job? Does 'new case bottom' mean the plastic only, or plastic plus hard drive, floppy drive, MLB, daughter card, cousin card and modem card? If you transferred those bits—and their various connectors—from the blue case bottom, what steps did you take against electrostatic damage? And so on, and so on.

Have you revisited your work to make sure that all connectors are properly mated? If the bottom work was a straight exchange with components already present, have you examined the components for integrity and the fit of connectors? There is just so much to speculate about without more description of the process from you.

To replace the flexible PC board (cable) to the display you needed to invade the top half of the case and the display, which must be done with care. How did you manage this?
