The disassembly procedure in the thread referenced just above applies to the early models of the Voyagers in which the logic and LCD assemblies may be separated from the keyboard assembly.
The later models (after 1984???) utilize a much less complex configuration in which the logic and display and keyboard are all constructed on one large PCB.
This difference makes some display or keyboard repairs that are possible on one version impossible or very challenging on the other.
Most descriptions of Voyager disassembly assume that the early internal configuration is what will be found. Even this site's museum shows, AFAIK, no photos of what is likely the more common later internal configuration.
Randy's (of Fix That Calc) recommendations would carry the most authority and promise for success.
