Troubleshooting Flow - Sony BCU-100 Maintenance Manual

1-9-3. Troubleshooting Flow

The troubleshooting flow is divided into three processes.
Check the basic items (briefly check the situation)
Check the status of the front panel LED (for the errors, check the error LED list)
(Refer to Section 1-9-5.)
Check by executing the self-diagnostic function in the Diag mode (for the error description,
check the error code list) (Refer to Section 1-9-6.)
Perform the following operations according to the result of the self-diagnostic function above.
When the error seems to be in a replacement component, replace that component.
When the error seems to be in a part other than replacement components, obtain the error code
number and required information, and take appropriate measures.
When no error is detected in the above processes, the trouble may be caused by the application
software.
In this case, contact the application software provider.
This diagnostic flow is designed to detect hardware or the firmware troubles. When no error is detected
after the check performed according to this flow, the trouble is more likely to be caused by a failure of the
application software.
