The context does not provide specific instructions for resetting the D string signal on a Parker Fly MIDI guitar with a Roland GR-55. However, general troubleshooting steps for signal issues with the GR-55 include:

1. Checking that all cables, connectors, and sockets are properly plugged in.
2. Cleaning the connectors and sockets using a contact cleaner like deOxit.
3. Trying a different cable to rule out a faulty connection.
4. Inspecting the 13-pin socket for possible dry joints.
5. Performing a factory reset on the GR-55 and reloading saved patches.

If the issue persists, the problem may be with the pickup or internal wiring of the guitar.
