CPU Troubleshooting
Communication failure to internal assemblies
Make sure that the connections to each of the internal assemblies is solid and
tight. When some assemblies are replaced others can become slightly
dislodged, causing communication errors, and assemblies to fail to be
identified. See the “Installed Board Info” section in Chapter 5, “Service and
Utility Menus,” and verify that all installed assemblies are being identified
properly.
Additional things to try:
Use Boot Service Menu to:
— Scan disks for errors, Scan all partitions for errors
— Boot in factory preset state (ignore last/user state)
— Boot in no hardware mode
Reset all instrument setting to default by pressing Utility, Power On/Preset,
Restore System Settings to Default Values, Confirm Restore Sys Settings to
Default Values
