Maintenance and Service 9-9
7. Align the new EPROM in the socket, making sure the EPROM’s
notch matches the notch on the circuit board (Figure 9-6).
Apply pressure to the center of the chip until it snaps down
into the socket. Press firmly to make sure it is seated properly
and ensure there are no bent or unseated pins.
8. Using Figure 9-5 as a reference, reassemble the CPC:
a. If disconnected, reconnect the ribbon cable connector to the
display board.
b. Replace the front panel, threading the inlet nozzle through
the hole on the panel and positioning the top of the panel so
it is level with the CPC chassis.
c. Replace four screws with washers on the CPC front panel,
attaching the panel to the side bars.
d. Replace four corner screws on the CPC front panel,
attaching the panel to the chassis.
e. Replace the top cover on the CPC. Make sure the vented
side of the cover is opposite the CPC fan. Attach the cover
with six screws.
9. Apply power to the CPC and make sure the LEDs function.
10. If the CPC is not functioning properly, remove power and make
sure the EPROM is positioned correctly and seated, and there
are no bent pins. If the CPC still does not function properly,
contact a TSI representative for assistance.
Failures
The microprocessor in the CPC checks many of the internal
parameters for functional failures. If your CPC should encounter
any of these failures, the front panel will read “FAILURE #X” where
“X” is the code number of the failure. The following table lists the
failures and possible ways to correct them. If you cannot fix the
problem yourself, call TSI for assistance.
