Eliminate Other Problem Sources
The TLA715 Portable Mainframe is part of the Tektronix Series Logic Analyzer
Family, which comprises modules and the mainframe. If power-on diagnostics
indicate that a module test failed, troubleshoot the module using the service
manual for that module.
Troubleshoot the Portable Mainframe
Follow the procedure in this section to identify the failed part within the portable
mainframe.
Testing may be required to correct some faults. Under those circumstances, you
will need the test equipment listed in the
Performance Verification Procedures
chapter of this manual.
Follow the primary troubleshooting tree in Figure 6--22 for fault isolation. This
tree calls for you to remove any installed modules, run the diagnostics programs,
and check for BIOS errors.
If you are unable to identify any problems through the troubleshooting tree or
through the diagnostic programs refer to
Isolating System Problems beginning on
page 6--48 for further troubleshooting information.
The primary diagnostics for the portable mainframe are the power-on diagnos-
tics, the CheckIt diagnostics, and the TLA Mainframe Diagnostics. Procedures
for running these diagnostics are described below.
