Checking internal components

To check the internal components, you must remove the side and front panels
of the ColorPASS.
Before you remove the ColorPASS's panels, be aware of the safety precautions you should
take when handling the ColorPASS. Use ESD precautions when handling printed circuit
boards and electronic components. To review the safety precautions, see "Precautions" on
page xiii.
Use the guidelines in Chapter 4, "Service Procedures." when disassembling, checking,
and reassembling the ColorPASS.
1. Shut down and open the ColorPASS (page 4-4 and page 4-5).
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 page 4-11).
Make sure no foreign materials have been dropped into the chassis.
• Look for obviously loose boards and reseat each board securely in its connector on
the motherboard.
• Look for cables that are obviously loose. Reseat each connector firmly.
• Make sure each connector is properly aligned with its mating connector. If the pins are
offset from each other, the board affected will not function properly.
4. Reassemble the ColorPASS and verify functionality (see page 4-14 and page 4-16).
