Description of Self-test Test Items C-15
The following dialog box appears when performing test. The system changes the
brightness of LED (white and orange) and trackball respectively and check whether
the brightness of LED on the keyboard changes accordingly. If LED brightness of the
keyboard keeps identical as configured, click “LED and Traceball is OK” to quit the
dialog box. If not, click “LED and Traceball is Bad” to quit the dialog box.
Suggestion to failure test
a) Replace the trackball if the trackball brightness does not respond.
b) Replace the control panel if LED brightness does not respond.
C.1.33 Z0701 LCD Monitor I2C Interconnection Test
Top test items
PC Module and DSP FPGA Interconnection Test
Test content
Read the display data from 12C bus, and judge whether it belongs to non 0 or non F,
and then parse LCD model, panel sequence number and LCD version number.
Analysis to test failure
The drive goes wrong if the test result appears Error.
The interconnection between DSP FPGA and LCD monitor goes wrong if the test
result is FAIL.
Suggestion to failure test
a) Restart the device and perform the self-test if the test result appears Error. It is
necessary to restore the device if Error re-appears.
b) Check whether the connecting material between LCD monitor and main unit is
fixed well, and then replace LCD EEPROM if the test result is FAIL.
C.1.34 Z0702 LCD Monitor Adjust Data Check Test
Top test items
LCD Monitor I2C Interconnection Test
Test content
The logic judges the progress status of the monitor and judges whether FLASH data
is consistent with the data on EEPROM via reading the register.
