GENERAL INFORMATION
This manual contains signature analysis tables for use with the diagnostic troubleshooting Information given in the
Maintenance section of the Volume 1 service manual.
The signature analysis method of troubleshooting is most applicable to digital circuits such as the microprocessor or
trigger logic; it is not an appropriate method of finding faults in analog circuits such as the powet supply, amplifiers, or
display control. Conventional troubleshooting methods for these circuits are located in the Maintenance section of the
Volume 1 service manual.
