Startup
ColorPASS does not start
up, or the Control Panel
is not backlit.
The ColorPASS is powered off.
Press the power button on the front of the ColorPASS.
Possibly one of the following:
•Power cable is not plugged into the
power connector on the ColorPASS
back panel or to the wall power
outlet
•Faulty power supply (power supply
may not be supplying power to the
motherboard)
•Faulty motherboard (motherboard
power plane may not be supplying
power to components)
•Faulty user interface board
1. Recheck all cables and connections.
2. Check power to the DVD drive.
If the LEDs are lit during startup and you are able to eject
the DVD drive tray, the drives are receiving power from
the power supply.
3. Listen for the power supply fan and feel for air at the back
of the unit where the power supply is located.
If you do not feel air from the power supply fan and the
drives are not receiving power, you may have a faulty
power supply, which you will need to replace
(see page 4-44).
4. Check the vent on the back panel to make sure air is
coming out the back of the system.
If the air is not coming out the back and the drives are not
receiving power, the motherboard is faulty and the
motherboard will need to be replaced (see page 4-22).
5. If you have verified that the power supply and the
motherboard are functioning properly, you may need to
replace the user interface board (see page 4-8).
Control Panel is lit
but discolored.
Possibly one of the following:
•User interface board cable or
connections are faulty
•User interface board is faulty
• CPU connection is loose
• CPU is faulty
•Motherboard is faulty
1. Recheck the user interface board cable and connections. If
the cable and connections are good and the problem
persists, replace the user interface board
(see page 4-8).
2. If the problem persists, verify CPU and CPU
fan connection. If the problem persists, you may need to
replace the CPU (see page 4-36).
3. If the problem persists, you may need to replace the
motherboard (see page 4-22).
Control Panel is
lit but no text appears.
User interface board is faulty.
Replace the user interface board (see page 4-8).
