circuit boards and electronic components. To review the safety precautions, see

O CHECK INTERNAL COMPONENTS
1 Shut down, and then open the ColorPASS.
2 Before you touch any components inside the ColorPASS, attach a grounding strap to
your wrist and discharge any static electricity on your body by touching a metal part of the
ColorPASS.
3 Inspect the inside of the ColorPASS (see Figure 12 on page 46 ).
Make sure that no foreign materials have been dropped into the chassis.
• Make sure that the DVD and hard disk drive data cables are connected to the correct
SATA connectors on the motherboard (see Figure 13 on page 48 ):
– DVD drive power/data combination cable to motherboard connector SATA 0
– Hard disk drive data cable to motherboard connector SATA 1
• Look for obviously loose boards and reseat each board securely in its connector on
the motherboard.
• Look for obviously loose cables and reseat each cable connector firmly.
• Make sure that each connector is properly aligned with its mating connector. If the pins
are offset from each other, the affected board will not function properly.
4 Reassemble the ColorPASS and verify its functionality (see page 103 ).
