Procedure.
1. Before you start to troubleshoot a problem, back up your instrument settings
to a preset. (See page 65, Back up your instrument settings.)
2. Check the diagnostics in the SPG8000 troubleshooting table. (See Table 15.)
The diagnostics check many of the signals that the Main board provides to
the BG board.
3. Run the slot I/O test on the Genlock/Black board. This tests many of the
signals needed by the BG board.
4. Use the Option BG troubleshooting diagram to troubleshoot the option. (See
Figure 23.)
