Time Machine Restore After New Logic Board

Older iMac (2009) had hard drive and logic board replaced. Running latest system (10.10.2) before and after logic board replacement.

When attempting to restore from a Time Machine backup made prior to the new logic board, although the iMac sees the Time Capsule and the "Data" file, attempts to proceed with the restore are met with error message "There was a problem connecting to the server [name of Time Capsule] - contact your administrator."

Any experience with this issue? Anybody successfully perform a restore following a new logic board?

Thanks very much.
