Troubleshooting
WARNING. Before performing this or any other procedure in this manual, read
the General Safety Summary and Service Safety Summary found at the
beginning of this manual. Also, to prevent possible injury to service personnel or
damage to electrical components, please read Preventing ESD on page 6–2.
This section contains information and procedures designed to help you isolate
faults within the benchtop controller. The process is as follows:
1. Do Check for Common Problems on page 6–24 to eliminate easy to find
problems first.
2. Do Eliminate Other Problem Sources on page 6–26 to eliminate the benchtop
chassis and other modules as the fault(s) source next.
3. Do Troubleshoot the TLA 711 Color Benchtop Controller Module on page
6–27 to locate the failed replaceable part within the module.
If you have replaced a faulty circuit board or assembly found using these
procedures, you must perform any verification and adjustment procedures
identified in Table 6–10 on page 6–41 for the replaced assembly or replaceable
part.
Service Level
